[mpich-discuss] MPICH2 & Large data

[Hisham Adel]

The problem is in the count number not in the data type.

Thanks  a lot

Send, using different MPI data types. For example MPI_INT instead of
MPI_CHAR, so element number will be 4 time smaller. The other way is to
split data to several messages.

Hi,

        

I am trying to send large data (2.5GB) using MPICH2. When the other
node is going to receive the data it can not cause in MPI_RECV (void *
buffer, Int count, .......) the count number will be very large than
the integer range.

        

how can I make it receive large data ?

Is there any solution for this problem ?

        

Thanks alot

        

Regards,

Hisham Adel
