Did you try using the Apple compiler too ?

Hi,
So you have 4 nodes each one with 2 processors, each processor 4-core
- quad-core.
So you have capacity for 32 process in parallel.
I think that only using the hostfile is enough is how I use. If you to
specify a specific host or a different sequence, the mpirun will obey
the host sequ
Ok, after all the considerations, I'll try Boost, today, make some
experiments and see if I can use it or if I'll avoid it yet.
But as said by Raimond I think, the problem is been dependent of a
rich-incredible-amazing-toolset but still implementing only
MPI-1, and do not implement all
Hi Raymond, thanks for your answer

I've used Boost MPI before and it really isn't that bad and
shouldn't be seen as "just another library". Many parts of Boost
are on their way to being part of the standard and are discussed and
debated on. And
serialization transparently and has some great natural
extensions to the MPI C interface for C++, e.g.
bool global = all_reduce(comm, local, logical_and());
This sets "global" to "local_0 && local_1 && ... && local_N-1"

Thank you very much John, the explanation of &v[0], was the kind of

This kind of approach solves my problems.

Hi,
So, after some explanation I start to use the bindings of C inside my C
++ code, then comme my new doubt:
How to send a object through Send and Recv of MPI ? Because the types
are CHAR, int, double, long double, you got.
Someone have any suggestion ?
Thanks.

There is a proposal that has passed one vote so far to deprecate the
C++ bindings in MPI-2.2 (meaning: still have them, but advise
against using them). This opens the door for potentially removing
the C++ bindings in MPI-3.0.
As h
st is working like a giant wrapper for many non-
OO things to C++, and it seems to use boost I have to install a lot of
additional things.
Thanks.
