Hi again.
I am using /etc/modprobe.d/mofed.conf, otherwise I get:
WARNING: Deprecated config file /etc/modprobe.conf, all config files belong
into /etc/modprobe.d/
But I am still getting the memory errors after making the changes and rebooting:
$ cat /etc/modprobe.d/mofed.conf
options mlx4_co
You can also set these parameters in /etc/modprobe.conf:
options mlx4_core log_num_mtt=24 log_mtts_per_seg=1

Greetings Ladies and gentlemen,
There is one alternative approach and this a psuedo-cloud based MPI. The
idea is that MPI node list is adjusted via the cloud similar to the way
Xgrid's Bonjour used to do it for Xgrid.
In this case, it is applying an MPI notion to the OpenCL codelets. There
are o

Add these to /etc/modprobe.d/mofed.conf:
options mlx4_core log_num_mtt=24
options mlx4_core log_mtts_per_seg=1
And then restart the driver.
You need to do it on all the machines.

Hi YK:
Yes, I have those installed but they are newer versions:
# rpm -qa | grep rdma
librdmacm-1.0.15-1.x86_64
librdmacm-utils-1.0.15-1.x86_64
librdmacm-devel-1.0.15-1.x86_64
# locate librdmacm.la
#
Here are the RPMs the Mellanox build created for kernel:
2.6.32-279.14.1.el6.x86_64
# ls *rdm
Joseph,

Hi All.
In compiling a simple Hello world with OpenMPI 1.6.3 and mpirun the hello

All,
I have a Fortran code that works quite well with OpenMPI 1.4.3 where I create
a handle using:
call MPI_TYPE_CREATE_F90_INTEGER(9, COMM_INT4, ierror)
and then do a reduction with:
call MPI_ALLREDUCE(send_buffer, buffer, count, COMM_INT4, MPI_SUM,
communicator,
ierror)

Ah, thanks - I was curious as Greenplum is about to release the full port of
Hadoop to OpenMPI so it can be run anywhere and support MPI as well. I'm at
least a little familiar with this one, but didn't realize it had been
distributed.

No problem! Glad to help.
I added you to the ticket about not being able to turn off the C++ compiler
checks (https://svn.open-mpi.org/trac/ompi/ticket/2999), in case that ever gets
fixed. It's somewhat of a low priority.

Thanks Jeff,
Of course you were right. I had thought the lost function was
something internal to y'alls build. It is pretty scary that they have
been building and porting for weeks (while I was running around SC and
the holidays) and it takes an old fortran guy to notice they don't have

Hi Ralph,
