Hi Ralph,
The Fortran code snippet is as follow...
<<<
...
write(*,*) "calling blacs_pinfo()..."
CALL BLACS_PINFO(IAM, NPROCS)
write(*,*), "after blacs_pinfo()..."
write(*,*), "IAM=", IAM
write(*,*), "NPROCS=", NPROCS
...
>>>
As you can notice, below-mentioned crash is happening in call to BLACS_PINFO().
I am using following environment:
OS: Windows 7 64-bit
Compilers: Visual Studio 2008 32bit and Intel ifort 32bit
OpenMPI: OpenMPI-1.5.3 pre-built libraries and also with
OpenMPI-1.5.2. locally built libraries
BLACS: pre-built libraries taken from
http://icl.cs.utk.edu/lapack-for-windows/scalapack/index.html#librairies
Thank you.
-Hiral
