TEG does not use the BTLs; thats why you got no errors.

The reason why I cannot do what you suggest below is because the

Hi Jeff,
Here are last night's reults of the following command on my 15 node
cluster. One node is down from 16.
mpirun --mca pml teg --mca btl_tcp_if_include eth1,eth0 --hostfile aa
-np 15 ./xhpl
No errors were spewed out to stdout as per my previous post when using
btl tcp and btl_tcp_if_inc

If there are 2 Ethernet cards it's better if you can point to the one you
want to use. For that you can modify the .openmpi/mca-params.conf fil

Dear Jeff, I reorganized my cluster and ran the following test with 15

Allan,
If there are 2 Ethernet cards it's better if you can point to the one you
want to use. For that you can modify the .openmpi/mca-params.conf file in
your home directory. All of the options can go in this file so you will
not have to specify them on the mpirun command every time.

Dear Jeff, Sorry I could not test the cluster earlier but I am having
problems with one compute node.(I will have to replace it!). So I will
have to repeat this test with 15 nodes. Yes I had 4 NIC cards on the
head node and it was only eth3 that was the gigabit NIC which was
communicating to ot
