Re: [OMPI users] debugging with mpirun

Hi I see that XMPI will do all that I need, but it says, it works with LAM/MPI up to versions 6.3.2 & 6.5.9, I am not sure if trying that with open/mpi will work or not, Thanks again, Manal On Fri, 2006-07-07 at 12:27 +1000, Manal Helal wrote: > thing that can show me varia

Re: [OMPI users] debugging with mpirun

or, if there is openMPI under Windows, where I can do some visual debugging, I appreciate any hints, because my application is getting too big, that printf are not doing any good, thanks, Manal On Fri, 2006-07-07 at 14:10 +1000, Manal Helal wrote: > Hi > > I see that XMPI will do all that I

Re: [OMPI users] MPI_Recv, is it possible to switch on/off aggresive mode during runtime?

Although it will add some overhead, have you tried using MPI_Probe before calling MPI_Recv. I am curious to know if the Probe is less CPU intensive than a direct call to MPI_Recv. An example of how I use it: MPI_Probe(MPI_ANY_SOURCE,MPI_ANY_TAG,MPI_COMM_WORLD,);

[OMPI users] readline and mpirun

When I run my MPI enabled application via mpirun, my application command-prompt looses its readline editing capability. I was wondering if there is workaround. Thanks. Saadat.

[OMPI users] Client Server

Hello All, I would like to know if anyone has tested Client server model using OpenMPI. Is there a place where i can get some simple example of this type of system. Thanks Abhinav

Re: [OMPI users] Dynamic COMM_WORLD

Hello, I have done some work on this using MPICH which is very similar to OpenMPI usage. The i think this is working as soon as you spawn a process it creates a intercommunicator and you can comunicate with the corresponding working using that intercommunicator. If you want to communicate
