[mpich-discuss] mpich2-1.2.1 on Cygwin/Vista

[Sherry Frese]

Thanks,

Unfortunately my applications are  both C and Fortran.  But so far 
I've been able to compile and link (using the MPICH2 libraries) 
on  my windows 7 machine.  I just can't run under mpiexec. (I've 
tried executables built on  the windows 7 machine  & older 
executables built under XP with the same results).

I'll wait to hear from you.
