[mpich-discuss] Using MPICH2 windows binary with PETSc

[Jayesh Krishna]

 Hi,

>> I am not sure MPICH2 for Windows supports Fortran. Did you check?
	MPICH2 on windows supports fortran. You must use the right fortran
library (See the windows developer's guide for details - available at
http://www.mcs.anl.gov/research/projects/mpich2/) to link your programs.

>> Even if it does, since you installed binaries, it may not support ifort.
	MPICH2 supports the Intel fortran compiler. You must link your
application (PETSc) with fmpich2.lib (available at MPICH2\lib) for fortran
support.

   What is the error that you get when you compile PETSc+MPICH2 ?
   Are you able to compile the sample application fpi.f available in the
MPICH2\examples directory ?

(PS: I will also check with the PETSc developers regarding this issue.)

Regards,
Jayesh

Subject: [mpich-discuss] Using MPICH2 windows binary with PETSc

Hi,

I'm trying to compile PETSc with MPICH2 in windows cygwin environment. 
May I know if it's possible?

I was initially using MPICH1 mpich.nt.1.2.5 and there's no problem. 
However I can't get it to work with MPICH2. I emailed the developers at
PETSc and they asked:

1) I am not sure MPICH2 for Windows supports Fortran. Did you check?

2) Even if it does, since you installed binaries, it may not support ifort.

Can you help to answer these questions?

Hope you can help.

Thank you very much.

Regards.
