Hi,
I am having a problem in running mpirun over multiple nodes.
To run a job over two 8-core processors, I generated a hostfile as follows:
yethiraj30 slots=8 max_slots=8
yethiraj31 slots=8 max_slots=8
These two machines are intra-connected and I have installed openmpi 1.3.3.
Then If I try

When I run 10 copies on the same node with btl tcp,self (no sm or openib),
valgrind reports the following to me (using ompi-1.4 branch HEAD):
==23753== Invalid write of size 1
==23753==at 0x4C6EA31: non_overlap_copy_content_same_ddt (dt_copy.h:170)

I'm afraid that we won't have an answer until our Windows guy comes back from
vacation. Sorry! :-(

This looks like your installation is busted somehow. Can you send all the
information listed here:

I've tried on my home Ubuntu 10.04, 64 bit version. It crashes with number
of ranks 5-7, 9 and greater. I simply downloaded 1.4.3 version (

Andrew,
I have a 8 octo-core nodes running under Caos NSA release 1.0.29 (Cato)
2009.11.13, connected with IB. I run your test one process per core, with
different distributions and all gave the same result.

Not exactly. I have 16 core nodes. Even if I run all 9 ranks on the same
node it fails (with --mca btl sm,self). I also tried running on different
nodes (3 nodes, 3 ranks each on each node) with openib and tcp - the same
effect. Also as I wrote in another message I could see this effect on vbox
Hi George,
Thanks a lot for your attempt! Possibly this is something OS specific? I'm
using CentOS release 5.4 x86_64 on the cluster. I also tried it on my
virtual box with CentOS 5.3 x86_64 (ompi 1.4.3). The same effect. On what OS
did you try? If it helps I can upload the virtual box image on

Andrew,
I tried with a freshly installed 1.4.3 but I can't reproduce your issue. I
tried with the 1.5 and the trunk and all complete your code without errors. Not
even valgrind found anything to complain about ...

Which version of OpenMPI are you using? There is no such
Hello list,
I have an application which uses MPI_Allgather with derived types. It works
correctly with mpich2 and mvapich2. However it crashes periodically with
openmpi2. After investigation I found that the crash takes place when I use
derived datatypes with MPI_AllGather and number of ranks
