Scalapack with 8-byte integers

I'm compiling a package (Molcas/GA) which I want to run in parallel, using the ScaLAPACK library.

On the Xeon machines, I use the libraries distributed with MKL (libmkl_blacs_openmpi_ilp64.a and libmkl_scalapack_ilp64.a).

We recently acquired machines with 4 Opteron 6276 processors and now I would like to run my program there.

As ACML doesn't seem to include ScaLAPACK, I compiled that myself. However, there does not seem to be an easy

way to get a version with 8-byte integers, and the package I use can't be linked to the standard 4-byte integer version.


Would anyone know how to get an 8-byte integer version of the ScaLAPACK library which is optimized for the Opteron 6200 series?


kind regards,
