Oh, well, when I wrote the stuff I described earlier, it was before
MPI existed, o
We can always build complicated solutions, but in some cases sane and
simple solutions exists. Let me clear some of the misinformation in this
thread.
The MPI standard is clear what type of conversion is allowed and how it
should be done (for more info read Chapter 4): no type conversion is
allowe
Dear colleagues,
FWIW, years ago I was looking at this problem and developed my
own solution (for C programs) with this structure:
--Be sure your code that works with ambiguous-length types like
'long' can handle different sizes. I have replacement unambiguous
typedef names like 'si32', 'ui64'
Let me shed a different light on that.
Once in a while, I run Open MPI between x86_64 and sparcv9, and it works
quite well as far as I am concerned.
Note this is the master branch, and I never try older nor releases branches.
Note you likely need to configure Open MPI with --enable-heteroge

The MPI standard states that if you send a message, you should receive the same

Sorry for a pedantic follow up:
Is this (heterogeneous cluster support) something that is specified by
the MPI standard (perhaps as an optional component)? Do people know if
MPICH. MVAPICH, Intel MPI etc support it? (I do realize this is an
OpenMPI forum)
The reason I ask is that I have a mini Li
