Re: [OMPI users] valgrind slaves in singleton mode

Actually, silly me. I didn't fully grok your note to see that you wanted to run valgrind on slaves generated via comm_spawn. That's a tad trickier, but not too hard to do. There actually is a "fork agent" you can define that will do what you want. If you do this: mpirun -mca orte_fork_agent

[OMPI users] MPI_Irecv does not receive all sends?

What I am trying to acheive in this simplified code is: - 2 types of processes (root, and children, ids/rank = 10 and 0-9 respectively) - init: - root will listen to children "completed" - children will listen to root notification when all has completed - while there is no

[OMPI users] valgrind slaves in singleton mode

Hi all - I'm using openmpi to spawn child processes in singleton mode. If I use mpirun, I can just run > mpirun valgrind myprog With spawn, it is expected that the spawned process will call mpi_init(_thread). If I want to run valgrind on my processes, what steps should be taken? I'm currently

Re: [OMPI users] MPI_Alltoallv performance regression 1.6.0 to 1.6.1

Hi, Simon, The pairwise algorithm passes messages in a synchronised ring-like fashion with increasing stride, so it works best when independent communication paths could be established between several ports of the network switch/router. Some 1 Gbps Ethernet equipment is not capable of doing so,
