Hi
Do you have any details about the performance of mxm, e.g. for real

Thanks

This is a question I raised before but for OpenMPI over IB.
I have build the app with the Portland compiler and OpenMPI 1.2.3 for
Myrinet and InfiniBand. Now I wish to run this on some nodes that have
no fast interconnect. We use GridEngine, this is the script:

I have built the release candidate for ga-4.1 with OpenMPI 1.2.3 and
portland compilers 7.0.2 for Myrinet mx.
Running the test.x for 3 Myrinet nodes each with 4 cores I get the
following error messages:
warning:regcache incompatible with malloc

I tried building Global Arrays with OpenMPI 1.2.3 and the portland
compilers 7.0.2. It gives an error message about an undefined symbol

I have OpenMPI-1.2.5 configured with myrinet and infiniband:
OMPI_MCA_btl=openib,self,sm
The job runs with the "error" message
"Error in mx_init (error MX driver not loaded.)"
which makes sense in itself as there is no myrinet card on the node.
Is it correct to assume that the ib

Hi
OpenMPI does not pick up the infiniband component on our nodes with
Mellanox cards:
ompi_info --param btl openib
returns
MCA btl: parameter "btl_base_debug" (current value: "0")
If btl_base_debug is 1 standard debug is output, if > 1 verbose
debug is output
MCA btl: parameter "btl"

Hi
I want to use SGE to run jobs on a cluster with mx and infiniband nodes.
By dividing the nodes into two host groups SGE will submit to either
interconnect.
The interconnect can be specified in the mpirun command with the --mca
btl parameter. However users would then have to decide at runtime
Is it possible to get information about the usage of hca ports similar
to the result of the mx_endpoint_info command for Myrinet boards?
The ibstat command gives information like this:
Port 1:
State: Active
Physical state: LinkUp
but does not say whether a job is actually using an infiniband

I am using OpenMPI 1.2.3 with SGE 6.0u7 over InfiniBand (OFED 1.2),
following the recommendation in the OpenMPI FAQ
http://www.open-mpi.org/faq/?category=running#run-n1ge-or-sge
The job runs but when the user wants to delete the job with the qdel
command, this fails. Does the mpirun command

Hello
I have compiled openmpi-1.2.3 with the --with-mx=
configuration and gcc compiler. On testing with 4-8 slots I get an error
message, the mx ports are busy:
