Problem

You have looked for linear algebra libraries BLAS and ScaLAPACK among the modules provided by the Cray Programming Environment without success.

Solution

BLAS and ScaLAPACK functions are provided by the cray-libsci module, that is loaded by default on Cray systems.

The following commands will give you some information on the module cray-libsci :

module show cray-libsci

module help cray-libsci

Please note that the Cray wrappers will automatically adjust the include and library path when cray-libsci  is loaded.

If you use the flag -craype-verbose when compiling with the wrapper, you will see a verbose list of all the include and library paths called by the compiler driver:

-craype-verbose
