<font face="Times New Roman, Times, serif">Hi, I've tested the
following</font> configurations:<br>
<br>
1)compiled as 64-bit : The application starts but while a
send/receive operation it stops. Maybe for the different mpi version<br>
<br>
2)compiled as 32-bit: on both systems: it works<br>
<br>
Thanks a lot<br>

<pre wrap="">Hi,
MPICH2 does not currently support heterogeneous systems (you cannot run an MPI job with a mix of 32-bit and 64-bit programs). Please compile myapp as a 32-bit exe on the 64-bit machine and let us know if it works for you.
Regards,
Jayesh

Hi Valerio,
I suppose you must have the same MPICH versions for both the PCs. Consequently, the applications must be 32-bit only.
Best ,
Oleg

Subject: [mpich-discuss] 32-bit 64-bit at the same time with mpi: question
Hi guys.
I have a question regarding this situation.
I have two machines, PC32 and PC64.
PC32 is a machine with a 32-bit OS installed , whereas PC64 has a 64-bit OS.
My script is
mpiexec -hosts 2 PC32 PC64 myapp.exe
myapp.exe is the my application compiled for 32-bit on the first machine and for 64 bit on the second one.
Is it possible to launch correctly the application? Or on the second machine the application must be compiled for 32-bit as well.
Thanks,
Valerio
