Hi,
On https://www.open-mpi.org/ I read:
> Full MPI-4.1 standards conformance
But on https://docs.open-mpi.org/ I read:
> In the Open MPI v5.0.x series, all MPI-3.1 functionality is supported.
*> Some* MPI-4.0 functionality is supported.

o the non-blocking collective proposed in
MPI 3.0. Otherwise you should implement your own based on non-blocking
point-to-point communications.

Hello
I got a problem with my code, wich run some kinf of a simulator.
I get 4 worker (aka 4 mpi process ) wich process data.
These data aren't available at the same time, so i get another process
(Splitter) wich send chunk of data to each process in round robin.
This work well using MPI_Sen
on | 10 ms BLOCK |
1000 ms execution and so on.
It's always the 8th process who block the programm.
Do someone experience any similar behavior?
Thanks

Hello
You have to copy nodeX public key at the end of nodeY authorizedkeys.

Hello
I think it's solved.
It's indeed the number of tick, and i found the information with the
otfinfo command, wich give me the line :
time resolution | 2.27 Ghz
This value allow us to convert these tick values to seconds values.
THanks all.

Hello
I'm generating otf file by compiling my programm with mpicc-vt.
It works very well and i can visualize the trace with the free Vampir.
But i need to analyze the results with some mathematical tools.
with vampir , i cannot extract any usefull data.
So i try to use otfdump to extract the
Right !
that's the problem when you work on someone else code.
Thanks

I've never seen that error output before - is it coming from your program? It

Hello
I'm extending a code currently working well on a server with some
quadri-core.
But for debugging purpose i want to execute it on my local computer.
When i use the command :
mpirun -np 6 -host local ./execFile
i get an :
ERROR: too many MPI processes
i've tried other mpi programs,
