[OMPI users] mpi daemon

2007-08-02 Thread Francesco Pietra
I compiled successfully the MD suite Amber9 on openmpi-1.2.3, installed om Debian Linux amd64 etch. Although all tests for parallel amber9 passed successfully, when I run ps -aux I don't see any daemon referring to mpi. How is that daemon identified, or how should it be started? Thanks france

The daemon's name is "orted" - one will be launched on each remote node as the application is started, but they only live for as long as the application is executing. Then they go away. On 8/2/07 12:47 PM, "Reuti" wrote: > Am 02.08.2007 um 18:32 schrieb Francesco Pietra: > >> I compiled succes

[OMPI users] values of mca parameters whilst running program

2007-08-02 Thread Glenn Carver
Hopefully an easy question to answer... is it possible to get at the values of mca parameters whilst a program is running? What I had in mind was either an open-mpi function to call which would print the current values of mca parameters or a function to call for specific mca parameters. I don

Jelena, George, Thanks for your replies. it is possible that the problem is not in MPI - I've seen similar problem on some of our workstations some time ago. Juan, are you sure you can allocate more than 2x 4GB memory of data in non-mpi program on your system? Yes, I did a small program that

Allocating memory is one thing. Being able to use it it's a completely different story. Once you allocate the 8GB array can you fill it with some random values ? This will force the kernel to really give you the 8GB of memory. If this segfault, then that's the problem. If not ... the proble
