Setting Up ORNL PVM Debugging

Totalview® User Guide : Part IV: Advanced Tools, Configuration, and Customization : Setting Up Parallel Debugging Sessions : Debugging PVM (Parallel Virtual Machine) Applications : Setting Up ORNL PVM Debugging

To enable PVM, create a symbolic link from the PVM bin directory (which is usually $HOME/pvm3/bin/$PVM_ARCH/tvdsvr) to the TotalView Server (tvdsvr). With this link in place, TotalView invokes pvm_spawn() to spawn the tvdsvr tasks.

For example, if tvdsvr is installed in the /opt/totalview/bin directory, enter the following command:

ln -s /opt/totalview/bin/tvdsvr \

$HOME/pvm3/bin/$PVM_ARCH/tvdsvr

If the symbolic link doesn’t exist, TotalView can’t spawn tvdsvr, displaying the following error:

Error spawning TotalView Debugger Server: No such file
