Hello,
I assume this question has been already discussed many times, but I can not

It is about buffer size limit of MPI_Send and MPI_Recv with heterogeneous
system (32 bit laptop / 64 bit cluster).
My configuration is :
open mpi 1.4, configured with: --wi

I will test it soon (takes some time to install the new version on each
node) . It would be perfect if it fixes it.
I will tell you the result asap
I have done the test with v1.4.2 and indeed it fixes the problem.
Thanks Nysal.
Thank you also Terry for your help. With the fix I do not need anymore to
