Subject: [OMPI users] Shared memory
From: Andrei Fokau (andrei.fokau_at_[hidden])

We use a C-program which consumes a lot of memory per process (up to few
GB), 99% of the data being the same for each process. So for us it would be
quite reasonable to put that part of data in a shared memory.

In the source code, the memory is allocated via malloc() function. What
would it require for us to change in the source code to be able to put that
repeating data in a shared memory?

The code is normally run on several nodes.
