Re: [OMPI users] memory limits on remote nodes

There is an MCA param that tells the orted to set its usage limits to the hard limit: MCA opal: parameter "opal_set_max_sys_limits" (current value: <0>, data source: default value) Set to non-zero to automatically set any system-imposed limits to the ma

[OMPI users] memory limits on remote nodes

Hi, We would like to set process memory limits (vmemoryuse, in csh terms) on remote processes. Our batch system is torque/moab. The nodes of our cluster each have 24GB of physical memory, of which 4GB is taken up by the kernel and the root file system. Note that these are diskless nodes, so no

Re: [OMPI users] Shared memory

When you use MPI message passing in your application, the MPI library decides how to deliver the message. The "magic" is simply that when sender process and receiver process are on the same node (shared memory domain) the library uses shared memory to deliver the message from process to process

Re: [OMPI users] Shared memory

Currently we run a code on a cluster with distributed memory, and this code needs a lot of memory. Part of the data stored in memory is the same for each process, but it is organized as one array - we can split it if necessary. So far no magic occurred for us. What do we need to do to make the magi

[OMPI users] my leak or OpenMPI's leak?

Hi I regularly use valgrind to check for leaks, but i ignore the leaks clearly created by OpenMPI, because i think most of them happen because of efficiency (lose no time cleaning up unimportant leaks). But i want to make sure no leaks come from my own apps. In most of the cases, leaks i am respons

Re: [OMPI users] Shared memory

Open MPI will use shared memory to communicate between peers on the sane node - but that's hidden beneath the covers; it's not exposed via the MPI API. You just MPI-send and magic occurs and the receiver gets the message. Sent from my PDA. No type good. On Oct 4, 2010, at 11:13 AM, "Andrei Fo

Hi everyone, I'm trying to build hdf5 1.8.5-patch1 on RHEL5 using openmpi 1.4 and the Intel Compiler suite 11.0. I have Fortran, MPI and shared library support enabled. I get this error at linking stage: /bin/sh ../../libtool --tag=FC --mode=link mpif90 -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=
