TotalView options.

Specifies the path name of the executable being debugged. This can be an absolute or relative path name. The executable must be compiled with debugging symbols turned on, normally the -g compiler option. Any multiprocess programs that call fork(), vfork(), or execve() should be linked with the dbfork library.

Specifies the name of a core file. Use this argument in addition to filename when you want to examine a core file with TotalView.

Default target program arguments.

Pass all subsequent arguments (specified by args) to the program specified by filename. This option must be the last one on the command line.

Defined only on AIX, a synonym for the platform-independent -use_fast_wp, for TotalView script backward compatibility . See -use_fast_wp for more information.You must set this option on the command line; you cannot set it interactively using the CLI.

Defined only on AIX, a synonym for the platform-independent -use_fast_trap, for TotalView script backward compatibility. See -use_fast_trap for more information. You must set this option on the command line; you cannot set it interactively using the CLI.

Specifies filename as the executable to debug, with args as optional arguments to pass to your program. This option must be listed last on the command line. You can also use --args instead of -args, for compatibility with other debuggers.

Sets the general background color to color.

Same as -background.

Enables handling of user-level (M:N) thread packages on BlueGene/Q systems.

(Alpha, HP, and SGI only.) Shows variables created by the Fortran compiler, as well as those in the user’s program.

Some Fortran compilers (HP f90/f77, HP f90, SGI 7.2 compilers) output debugging information that describes variables the compiler itself has invented for purposes such as passing the length of character*(*) variables. By default, TotalView suppresses the display of these compiler-generated variables.

However, you can specify the -compiler_vars option to display these variables. This is useful when you are looking for a corruption of a run-time descriptor or are writing a compiler.

(Default) Tells TotalView that it should not show variables created by the Fortran compiler.

(Default) Tells TotalView to kills attached processes and exits.

Invokes code that sometimes allows TotalView to better manage the way it kills parallel jobs when it works with management systems. This has only been tested with SLURM. It may not work with other systems.

(Default) Enables CUDA debugging with TotalView.

Disables CUDA debugging. Any CUDA kernels launched on a GPU device are not seen by the debugger, so the debugger can only debug the host code. -nocuda is the identical command.

(Default) Catches the fork(), vfork(), and execve() system calls if your executable is linked with the dbfork library.

Tells TotalView that it should not catch fork(), vfork(), and execve() system calls even if your executable is linked with the dbfork library.

Redirects TotalView console output to a file named console_outputfile.

If consoleoutputfile is the string UNIQUE, the filename tv_dump.hostname.pid is used. If console_outputfile contains the string '$$' (note the escaping single quotes), hostname.pid is substituted. UNIQUE and '$$' are useful for separating the console output when running multiple tvdsvr processes.

All TotalView console output is written to stderr.

Specifies a set of MPI ranks to be attached to when an MPI job is created or attached to. The subset_specification is a space-separated list, the elements of which can be in one of these forms:

rank1-rank2:stride: every strideth rank between rank1 and rank2

A rank must be either a positive decimal integer or max (the last rank in the MPI job).

A subset_specification that is the empty string ("") is equivalent to 0-max.

The default_parallel_attach_subset is used to initialize the parallel_attach_subset property of an MPI starter process, which can be get or set in the CLI using:

The CLI dattach and dload -parallel_attach_subset subset_specification overrides the default_parallel_attach_subset and sets the parallel_attach_subset property of the process being attached or loaded.

Overrides the demangler and mangler TotalView uses by default. The following indicate override options.

-demangler=compaq: HP cxx on Linux (alpha)

-demangler=gnu: GNU C++ on Linux Alpha

-demangler=gnu_dot: GNU C++ on Linux x86

-demangler=gnu_v3: GNU C++ Linux x86

-demangler=kai: KAI C++

-demangler=kai3_n: KAI C++ version 3.n

-demangler=kai_4_0: KAI C++

-demangler=spro: SunPro C++ 4.0 or 4.2

-demangler=spro5: SunPro C++ 5.0 or later

-demangler=sun: Sun CFRONT C++

-demangler=xlc: IBM XLC/VAC++ compilers

Set the name of the X Windows display to displayname. For example, -display vinnie:0.0 will display TotalView on the machine named “vinnie.”

The colon-separated argument to this option tells TotalView that it should ignore files having this prefix when making a decision to ask about stopping the process when it dlopens a dynamic library. If the DLL being opened has any of the entries on this list as a prefix, the question is not asked.

The colon-separated argument to this option tells TotalView that if the library being opened has any of the entries on this list as a suffix, it should ask if it should open the library.

Allows TotalView to dump a core file of itself when an internal error occurs. This is used to help Rogue Wave Software debug problems.

Tells TotalView to immediately execute the CLI commands named within this argument. All information you enter here is sent directly to the CLI’s Tcl interpreter. For example, the following writes a string to stdout:

You can have more than one -e option on a command line.

Tells TotalView that it should only use an Enterprise license.

Tells TotalView that it should not use an Enterprise license. You may combine this with -no_team or -noteamplus.

Tells TotalView to add an environment variable to the environment variables passed to your program by the shell. If the variable already exists, it effectively replaces the previous value. You need to use this command for each variable being added; that is, you cannot add more than one variable with an env command.

Sets the general foreground color (that is, the text color) to color.

Same as -foreground.

Overrides the Fortran demangler and mangler TotalView uses by default. The following indicate override options.

-demangler=spro_f9x_4: SunPro Fortran, 4.0 or later

-demangler=xlf: IBM Fortran

(Default) Lets TotalView assume that type names are globally unique within a program and that all type definitions with the same name are identical. The C++ standard asserts that this must be true for standard-conforming code.

If this option is set, TotalView will attempt to replace an opaque type (struct foo *p;) declared in one module, with an identically named defined type in a different module.

If TotalView has read the symbols for the module containing the non-opaque type definition, then when displaying variables declared with the opaque type, TotalView will automatically display the variable by using the non-opaque type definition.

Specifies that TotalView cannot assume that type names are globally unique in a program. You should specify this option if your code has multiple different definitions of the same named type, since otherwise TotalView can use the wrong definition for an opaque type.

Tells TotalView that if a program or library has a .gnu_debug_link section, it should look for a gnu_debug_link file. If found, TotalView reads the debugging information from this file.

Do not load information from a gnu_debug_link file even if the file has a .gnu_debug_link section.

Tells TotalView that it should validate the gnu_debug_link file’s checksum against the checksum contained in the process’s .gnu_debuglink section.

Do not compare checksums. Only do this if you are absolutely certain that the debug file matches.

Directs TotalView to support IPv6 addresses.

(Default) Do not support IPv6 addresses.

(Default) Converts structure definitions output by the KCC compiler into classes that show base classes and virtual base classes in the same way as other C++ compilers. See the description of the TV::kcc_classes variable for a description of the conversions that TotalView performs.

Specifies that TotalView will not convert structure definitions output by the KCC compiler into classes. Virtual bases will show up as pointers, rather than as data.

(Default) Loads action points automatically from the filename.TVD.v3breakpoints file, providing the file exists.

Tells TotalView that it should not automatically load action points from an action points file.

Loads into TotalView the session named in session_name. If the preference “Show Startup Parameters when TotalView starts” is set, this option launches the Session Manager’s Program Session screen where you can edit the session’s properties and then launch the session; otherwise, the option immediately loads the session into TotalView, launching the Root and Process windows. Session names with spaces must be enclosed in quotes, for example, "my debug session". Sessions that attach to an existing process cannot be loaded using this option; rather, use the -pid option instead.

Sets the interface name that the server uses when it makes a callback. For example, on an IBM PS2 machine, you would set this to css0. However, you can use any legal inet interface name. (You can obtain a list of the interfaces if you use the netstat -i command.)

Enables memory debugging. By adding the following suboptions, you enable that particular feature using its the feature’s default configuration. In most cases, you will want to use one or more of the following sub-options.

Tests for memory use after memory is freed.

Surrounds allocated memory blocks with guard blocks.

Tells the Memory Debugger to hoard memory blocks instead of releasing them when a free() routine is called.

Sets the low memory threshold amount. When memory falls below this amount an event will be fired.

Turns on memory event notification.

-no_mem_notify_events turns event notification off.

Paint both allocated and deallocated blocks with a bit pattern.

Paint memory blocks with a bit pattern when they are allocated.

Paint memory blocks with a bit pattern when they are freed.

Turn on testing for Red Zones overruns.

Defines the memory allocations ranges for which Red Zones are in effect. Ranges can be specified as follows: x:y allocations from x to y.

:y allocations from 1 to y

x: allocations of x and higher

x allocation of x

Turn on testing for Red Zones underruns.

(Default) Enables the display of MPI message queues when debugging an MPI program.

Same as -message_queue.

Disables the display of MPI message queues when you are debugging an MPI program. This might be useful if something is overwriting the message queues and causing TotalView to become confused.

Same as -no_message_queue.

Names the MPI that your program requires. The list of starter names that you enter are those that appear in the Parallel system pull down list contained within the New Program’s Parallel tab. If the starter name has more than one word (for example, Open MPI), enclose the name in quotes. For example:

Specifies the number of nodes upon which the MPI job will run.

Tells TotalView not to reference any initialization files during startup. Note that this negates all settings in all initialization files. Aliases are -nostartupscripts and -nss.

By default, the cursor in the source pane of the process window turns into a hand cursor when hovering over an element you can dive on (a red box is also drawn around the applicable code). Specify this option to override this behavior and retain the usual arrow cursor.

Specifies how many tasks that TotalView should launch for the job. This argument usually follows a -mpi command-line option.

Tells TotalView that your application is using NPTL threads. You only need use this option if default cannot determine that you are using this threads package.

Tells TotalView that you are not using the NPTL threads package. Use this option if TotalView thinks your application is using it and it isn’t.

Displays the Root Window used in versions prior to TotalView 8.15.0. Using ‑oldroot or ‑newroot overrides the TV::GUI::old_root_window value.

(Default) Enables handling of parallel program run-time libraries such as MPI, PE, and UPC.

Disables handling of parallel program run-time libraries such as MPI, PE, and UPC. This is useful for debugging parallel programs as if they were single-process programs.

Sets the action that TotalView takes when starting a parallel program. Possible options are:

yes (default) Attaches to all processes in a parallel program, unless the process being launched or attached to has a non-empty parallel_attach_subset property. In this case, only the subset of processes specified in the parallel_attach_subset are attached.

no: Attaches to no processes in a parallel program.

ask Asks which processes to attach to by posting the subset attach dialog box if the debugger GUI is open.

This option works in concert with the parallel_attach_subset property (see default_parallel_attach_subset) of an MPI starter process, which specifies a set of MPI tasks to attach to when the debugger launches or attaches to an MPI job.

Modifying this setting does not affect the parallel_attach_subset property itself.

Allocates the patch space dynamically at address. See “Allocating Patch Space for Compiled Expressions” in the TotalView User Guide.

Sets the length of the dynamically allocated patch space to this length. See “Allocating Patch Space for Compiled Expressions” in the TotalView Users Guide.

Tells TotalView to attach to process pid for executable filename when TotalView starts executing.

Specifies how many tasks that TotalView should launch for the job. This argument usually follows a -mpi command-line option.

Specifies that TotalView display the Processes/Ranks Tab in the Process Window. Note that enabling this tab can significantly affect performance, particularly for large, massively parallel applications.

Debugs an executable that is not running on the same machine as TotalView. For hostname, you can specify a TCP/IP host name (such as vinnie) or a TCP/IP address (such as 128.89.0.16). Optionally, you can specify a TCP/IP port number for portnumber, such as :4174. When you specify a port number, you disable the autolaunch feature. For more information on the autolaunch feature, see “Setting Single Process Server Launch” in the TotalView Users Guide.

Same as -remote.

Tells TotalView that it should enable the ReplayEngine when TotalView begins. This command-line option is ignored if you do not have a license for ReplayEngine.

Specifies the path name of a startup file that will be loaded and executed. This path name can be either an absolute or relative name.

You can add more than one -s option on a command line.

Debugs an executable that is not running on the same machine as TotalView. For device, specify the device name of a serial line, such as /dev/com1. Currently, the only option you are allowed to specify is the baud rate, which defaults to 38400. For more information on debugging over a serial line, see “Debugging Over a Serial Line” in Chapter 4 of the TotalView Users Guide.

Specify a colon-separated list of directories that TotalView will search when it looks for source files. For example:

totalview -search_path proj/bin:proj/util

Modifies the way in which TotalView handles signals. You must enclose the action_list string in quotation marks to protect it from the shell.

An action_list consists of a list of signal_action descriptions separated by spaces:

signal_action[ signal_action] ...

A signal action description consists of an action, an equal sign (=), and a list of signals:

action=signal_list

An action can be one of the following: Error, Stop, Resend, or Discard, For more information on the meaning of each action, see Chapter 3 of the TotalView User Guide.

A signal_specifier can be a signal name (such as SIGSEGV), a signal number (such as 11), or a star (*), which specifies all signals. We recommend that you use the signal name rather than the number because number assignments vary across UNIX sessions.

The following rules apply when you are specifying an action_list:

(1) If you specify an action for a signal in an action_list, TotalView changes the default action for that signal.

(2) If you do not specify a signal in the action_list, TotalView does not change its default action for the signal.

(3) If you specify a signal that does not exist for the platform, TotalView ignores it.

(4) If you specify an action for a signal more than once, TotalView uses the last action specified.

If you need to revert the settings for signal handling to built-in defaults, use the Defaults button in the File > Signals dialog box.

For example, here’s how to set the default action for the SIGTERM signal to resend:

Here’s how to set the action for SIGSEGV and SIGBUS to error, the action for SIGHUP to resend, and all remaining signals to stop:

Same as -signal_handling_mode.

Tells TotalView to pass arguments to the starter program. You can omit the quotation marks if arguments is just one string without any embedded spaces.

Names the file to which TotalView writes the target program’s stderr information while executing within TotalView. If the file exists, TotalView overwrites it. If the file does not exist, TotalView creates it.

Tells TotalView to append the target program’s stderr information to the file named in the -stderr command, specified in the GUI, or in the TotalView TV::default_stderr_filename variable. If the file does not exist, TotalView creates it.

Tells TotalView to redirect the target program’s stderr to stdout.

Names the file from which the target program reads information while executing within TotalView.

Names the file to which TotalView writes the target program’s stdout information while executing within TotalView. If the file exists, TotalView overwrites it. If the file does not exist, TotalView creates it.

Tells TotalView to append the target program’s stdout information to the file named in the -stdout command, specified in the GUI, or in the TotalView TV::default_stdout_filename variable. If the file does not exist, TotalView creates it.

Specifies how many tasks that TotalView should launch for the job. This argument usually follows a -mpi command-line option.

Tells TotalView that it should only use a Team license.

Tells TotalView that it should not use an Enterprise license. You may combine this with -no_ent or -noteamplus.

Tells TotalView that it should only use a Team Plus license.

Tells TotalView that it should not use a Team PLus license. You may combine this with -no_ent or -noteam.

The directory from which TotalView reads preferences and other related information and the directory to which it writes this information.

Controls TotalView’s use of the target operating system’s support of the fast trap mechanism for compiled conditional breakpoints, also known as EVAL points. As of TotalView 8.7, when this was introduced, only AIX supported the fast trap mechanism for breakpoints, but we anticipate other operating systems adding support. You must set this option on the command line; you cannot set it interactively using the CLI.

Your operating system may not be configured correctly to support this option. See the TotalView Release Notes on our web site for more information.

Controls TotalView’s use of the target operating system’s support of the fast trap mechanism for compiled conditional watchpoints, also known as CDWP points. As of TotalView 8.7, when this was introduced, only AIX supported the fast trap mechanism for watchpoints, but we anticipate other operating systems adding support. You must set this option on the command line; you cannot set it interactively using the CLI.

Your operating system may not be configured correctly to support this option. See the TotalView Release Notes on our web site for more information.

(Default) Enables handling of user-level (M:N) thread packages on systems where two-level (kernel and user) thread scheduling is supported. (Note: This option does not apply to BlueGene/Q systems; instead, see -bluegene_q_user_threads.)

Disables handling of user-level (M:N) thread packages. This option may be useful in situations where you need to debug kernel-level threads, but in most cases, this option is of little use on systems where two-level thread scheduling is used.

Sets the verbosity level of TotalView messages to level, which may be one of silent, error, warning, or info.

Sets the name of the program used when TotalView needs to create a the CLI. If you do not use this command or have not set the TV::xterm_name variable, TotalView will attempt to create an xterm window.
