[mpich-discuss] 32-bit 64-bit at the same time with mpi: question

[Oleg Gamov]

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
