[mpich-discuss] mpich2 MPI_TEST errors

[Samir Khanal]

Hi all

I was trying to get a library compiled using mpich2, 
it works ok - compiles and executes with mpich 1.2.7 ch3_p4 channel and 1.2.5 but i have problem running it with mpich2.
Isn't mpich2 backward compatible with mpich 1.2.7 ? I assume that there should not be specific rewrites to work with mpich2... 
I compiled mpich2  with 
--with-device=ch3:nemesis

and all other 3 options 
sock
ssm
shm

what should be the channel to be compatible with ch3_p4 as in mpich-1.2.7

The error i receive is 

mpiexec -n 1 ./test
Fatal error in MPI_Test: Invalid MPI_Request, error stack:
MPI_Test(152): MPI_Test(request=0x869e1dc, flag=0xbfa134f8, status=0xbfa134d0) failed

i am using correct mpicxx and mpicc and mpi.h versions in includes 
infact i use 
include "mpi.h" so that appropriate version header gets pulled in automatically

I also have another question

I want to compile mpich2 for another cluster with 6 pcs with intel core2quad processors, what appropriate channels should  be used?

Thanks
