nefit, you will be able to use the mpool instead of malloc, which should moderate the overhead of creating the intermediate buffer. I will have a look at that. Thomas Aurelien Le 8 janv. 09 à 05:13, Thomas Ropars a écrit : Hi, I submit again this old question because I didn't get any a

Hi, I've tried to use ompi-server to connect 2 processes belonging to different jobs but running on the same computer. It works when the computer has a network interface up. But if the only active network interface is the local loop, it doesn't work. According to what I understood reading the co

Hello, I don't have a common file system for all cluster nodes. I've tried to run the application again with VT_UNIFY=no and to call vtunify manually. It works well. I managed to get the .otf file. Thank you. Thomas Ropars Andreas Knüpfer wrote: Hello Thomas, sorry for the

Hi all, I'm trying to use VampirTrace. I'm working with r19234 of svn trunk. When I try to run a simple application with 4 processes on the same computer, it works well. But if try to use the same application with the 4 processes executed on 4 different computers, I never get the .otf file.

Re: [OMPI users] MPI piggyback mechanism

Sorry for my late reply. And thank you all for your answers and comments. Oleg, Same question as Aurélien. You mentionned that you have implemented some piggyback mechanisms in Open MPI. Are these mechanisms available ? Would it be possible to use it ? Regards. Thomas Ropars Aurélien

Hi, I'm currently working on optimistic message logging and I would like to implement an optimistic message logging protocol in OpenMPI. Optimistic message logging protocols piggyback information about dependencies between processes on the application messages to be able to find a consistent
