-# Make.sys for Cray xt4, using ACML & ScaLAPACK & MPI+OPENMP
-# Courtesy of Filippo Spiga, 02/2010 . Remarks:
-# - use environment MPI "xt-mpt/3.5.1" (latest available Cray release )
-# - do not use xt-libsci: "module unload xt-libsci"
-# - PGI 8.x or PGI 9.x compiler
-# - ACML 4.2.0 or 4.3.0. Should be statically linked. If you run into trouble,
-#   unload them: "module unload acml" 
-# - hand-compiled ScaLAPACK+ BLACS
-# - "ulimit -s unlimited" and "export OMP_STACKSIZE=500M" when submitting
-#   (maybe one can try with les than 500Mbytes)
