[mpich-discuss] MPICH2

[Jayesh Krishna]

Hi,
 I have seen this issue before on my Windows machine when its domain changed and the permission for Cygwin files were messed up.
 You can try debugging the permission issue in your machine or try using sysv shared memory when building MPICH2 (./configure ... --with-shared-memory=sysv). You can find some background info about this issue at https://trac.mcs.anl.gov/projects/mpich2/ticket/837 .

Regards,
Jayesh

Hi, 
thank you for your answer , 
Actually, when I run the program with a single processor " mpiexec -n 1 . / a.out " it works and when I put " mpiexec -n 2 . / a.out " it gives me the error : Fatal error in MPI_Init: Other MPI error, error stack: ...... 

I have " Intel ( R ) Core ( TM ) 2 Duo CPU "

Hi, 
If you have installed MPICH2 on versions of Windows post-Vista (Vista, Windows 7, long horn etc), try running the cygwin bash shell from an administrative command prompt (Right-click on command prompt icon and select "Run as administrator" . From within this command prompt type "bash" to run the cygwin bash shell.) and let us know if it works. 

Regards, 
Jayesh
