[Bug 231062] Re: Segmentation fault while sending large arrays

[Emmanuel FARHI]

One possible solution is to split arrays in small bits, e.g. only 1000 or 10000 elements being sent/received, and catenate messages to rebuild original array. 
I attach example implementations for Reduce, Send and Recv calls (file: mpi_split-blocks.txt).
