Is Scalapack compatable with AMD Opeteron 64-bit processors?

[postaquestion]

I have installed the Cluster Toolkit 3.0 on my AMD Opteron 64-bit processor. On the website http://www.intel.com/cd/software/products/asmo-na/eng/266861.htm it says that the Scalapack is tuned for Intel processors.

Is Scalapack tuned/compatible to AMD Opteron Processors also?

Iam asking because when I tried to test the Scalapack in /intel/3.0/cmkl/9.0/tests/scalapack...the error I am getting is:

mpiifort -c -w -u -O0 psludriver.f
ERROR: LD_LIBRARY_PATH set up wrong for driver: mpiifort
(could not find expected library in LD_LIBRARY_PATH)

Isa configuration problem or compatibility problem?

mpiifort requires that the ifort and Intel MPIenvironment variables be set. ifortvars and mpivars scripts will do it. This is not done automatically for any brand of CPU. In addition, you would have to set the library paths for Scalapack. You must choose compatible versions of each script (e.g. all 64-bit versions, or all 32-bit). 64-bit ifort is normally installed under fce, and 64-bit Intel MPI environment script would install in a /bin64 directory. Some of my colleagues have requested a consistent form for the install paths.

MKL runs on competitive processors well. The problems you have noted arise from your environment for the compiler, as Tim noted. --Bruce
