7.2 BLA Library Dependency

Select which Basic Linear Algebra (BLA) library to use, which is required by the Math Module. Note: Intel MKL and Sun SPL are performance-enhanced libraries for their respective platforms.

When creating your buildspec in RCB, you choose the Basic Linear Algebra (BLA) library your applications will use:

• the SourcePro C++ BLA library -- Windows and UNIX

• the Intel Math Kernel Library (MKL) -- Intel's MKL library on Linux, and Windows

• the Sun Performance Library (SPL) -- Solaris only

When configuring your build, which BLA libraries are available for selection depends on the chosen platform.

On Windows, you have the choice of using the SourcePro C++ BLA library or the MKL BLA library.

If you select the SourcePro C++ BLA library when defining the buildspec, the BLA library is in the buildspace lib directory, with a name such as bla8s.lib. When you build your applications, be sure to link in this BLA library.

If you select the MKL library when defining the buildspec, you must specify the libraries to be used by the compiler.

SourcePro C++ supplies the MKL libraries with the Essential Math Module distribution. RCB takes care of making the MKL libraries available when it builds the Essential Math Module library.

When building your applications, the MKL libraries must be accessible. There are two ways you can ensure accessibility:

• Move the libraries to a known location, such as the Windows system directory.

• Edit your PATH variable to include the location of the MKL libraries.

The libraries below indicate the MKL libraries that are required for different environment choices. One of these options must in your link line.

Windows - Static Linking 32-bit

Libraries are located in buildspace\3rdparty\mkl\mkl7.2\winos\ia32\lib. The buildspace is the directory where the product is installed.

• mkl_c.lib mkl_lapack.lib mkl_p3.lib
  Cdecl interface for 32-bit porcessor static linking, LAPACK and BLAS libraries, Pentium III processor kernel.

• mkl_c.lib mkl_lapack.lib mkl_p4.lib
  Cdecl interface for 32-bit processor static linking, LAPACK and BLAS libraries, Pentium 4 kernel.

• mkl_c.lib mkl_lapack.lib mkl_def.lib
  Cdecl interface for 32-bit processor static linking, LAPACK and BLAS libraries, default processor kernel. Pentium, Pentium Pro, Pentium II processors.

Windows - Dynamic Linking 32-bit

Libraries are located in buildspace\3rdparty\mkl\mkl7.2\winos\ia32\lib and DLLs are located in buildspace\3rdparty\mkl\mkl7.2\winos\ia32\bin (PATH variable must contain this path). The buildspace is the directory where the product is installed.

• mkl_c_dll.lib
  Cdecl interface for 32-bit processor dynamic linking. The DLL dispatcher loads the appropriate .dll for the processor dynamic kernel.

Excluding Solaris and Linux, you must use the SourcePro C++ BLA library on UNIX platforms.

When you build your applications, you must link in the SourcePro C++ BLA library located in the buildspace lib directory, with a name such as bla8s.lib.

You have the choice of using the SourcePro C++ BLA library or the MKL BLA library on a Linux platform.

The libraries below indicate the MKL libraries that must appear in your link line, depending on your environment choices.

Linux - Static Linking 32-bit

Libraries are located in buildspace/3rdparty/mkl/mkl7.2/linux/lib/32. The buildspace is the directory where the product is installed.

• libmkl_lapack.a libmkl_p3.a
  32-bit processor static linking, LAPACK library, Pentium III processor kernel.

• libmkl_lapack.a libmkl_p4.a
  32-bit processor static linking, LAPACK library, Pentium 4 processor kernel.

Linux - Dynamic Linking 32-bit

Libraries are located in buildspace/3rdparty/mkl/mkl7.2/linux/lib/32. The buildspace is the directory where the product is installed.

• libmkl.so -lguide -lpthread
  32-bit processor dynamic linking. DLL dispatcher loads the appropriate .so for the processor dynamic kernel.

You have the choice of using the SourcePro C++ BLA library or the Sun Performance Library, SPL on a Solaris platform.

You must install SPL before you can select it. You must get the compiler from the Sun web site, www.sun.com.

With SPL, you do not need to provide the names of the libraries, but you do need to add the following flags to your compile and link lines:

• -xlic_lib=sunperf at the end of the lines

• -lmtsk anywhere on the lines, for multithreaded builds
