Thanks for your help,

separate messages asynchronously to root.
Thanks again,

I'm not sure if you understood my question. The case is not trivial at all
or I miss something important.
Try to design this derived datatype and you will understand my point.
Thanks anyway.

index i. How can I define a datatype that spans this pair over both arrays?
The only additional constraint it the fact that the memory location of both
arrays is fixed and cannot be changed and I should avoid extra copies.
Is it possible?
Any help welcome,

Hi,
I'm developing a causality chain tracking library and need a mechanism to
attach an extra data to every MPI message, so called piggyback mechanism.
As far as I know there are a few solutions to this problem from which the
two fundamental ones are the following:
- Dynamic datatype wrapping
opted
for MRNet infrastructure (multicast/reduction network,
http://www.paradyn.org/mrnet/release-1.1/UG.html).

Hello,
In the context of my PhD research, I have been developing a run-time
performance analyzer for MPI-based applications.
My tool provides a controller process for each MPI task. In particular, when
a MPI job is started, a special wrapper script is generated that first
starts my controller proc
