Re: [OMPI users] Directed to Undirected Graph

You need to use 2 calls. One option is an Allgather followed by an Allgatherv. Allgather() with one integer, which is the number of nodes the rank is linked to Allgatherv() with a variable size array of integers where each entry is a connected to node On 06/05/2012 08:39 AM, Mudassar Maje

This looks like a missing check in the sctp configure.m4. I am working on a patch. --td On 6/5/2012 10:10 AM, Siegmar Gross wrote: Hello, I compiled "openmpi-1.6" on "Solaris 10 sparc" and "Solaris 10 x86" with "gcc-4.6.2" and "Sun C 5.12". Today I searched my log-files for "WARNING" and fou

Re: [OMPI users] seg fault with intel compiler

First of all, thanks to everyone who took the trouble to offer suggests. The solution seems to be to upgrade the Intel compilers. However, I'm not the cluster admin, so other crucial changes may have been implemented. For example, I know that ssh was reconfigured over the weekend (but that shouldn

[OMPI users] Directed to Undirected Graph

Dear people,    Let say there are N MPI processes. Each MPI process has to communicate with some T processes, where T < N. This information is a directed graph (and every process knows only about its own). I need to convert it to undirected graph, so that each process will
