Re: [bgl-discuss] ScaLapack or PESSL

[Satish Balay <balay@xxxxxxxxxxx>]

I have these packages installed as part of PETSc build. This version
is modified to to not have any internal blas/lapack symbols [so
external blas/lapack package needs to be used]

You might want to use the following [with mpicc.ibm-8.0, mpif90.ibm-9.1]

BLACS : 
  -L/soft/tools/petsc/petsc-2.3.1-p13/externalpackages/blacs-dev/bgl-ibm-opt -lblacs
SCALAPACK:
  -L/soft/tools/petsc/petsc-2.3.1-p13/externalpackages/SCALAPACK/bgl-ibm-opt -lscalapack
BLAS/LAPACK:
  -L/soft/tools/lapack440 -llapack440 -lblas440

There is ESSL at /soft/tools/essl-rev1/libessln.a - but I don't know about PESSL

Susan.

Is there a '440d' version of blas/lapack? Is this somethig obtained
from IBM or something we compiled from source? [if from sources, I
could easily build a 440d version myself]

thanks,
Satish
