Your best option is to distill this down to a short example program which shows

I don't believe we ever got anywhere with this due to lack of response. If you
get some info on what happened to tm_init, please pass it along.
Best guess: something changed in a recent PBS Pro release. Since none of us

Hi,
I am using Open MPI to do data transfer from master node to worker nodes.
But, the worker node can the data which is not what it should get.
I have checked destination node rank, taskTag, datatype, all of them are
correct.
I do an experiment.
Node 0 sends data to node 1 , 2 ,3.
Only nod
Thank you very much, Ralph.
Heck, it had to be something stupid like this.
Sorry for taking your time.
Yes, switching from "slots" to "slot" fixes the rankfile problem,
and both cases work.
I must have been carried along by the hostfile syntax,
where the "slots" reign, but when it comes to bindi
I normally hide my eyes when rankfiles appear, but since you provide so much
help on this list yourself... :-)
I believe the problem is that you have the keyword "slots" wrong - it is
supposed to be "slot":
rank 1=host1 slot=1:0,1
rank 0=host2 slot=0:*
rank 2=host4 slot=1-2
rank
Dear Open MPI pros
I am having trouble to get the mpiexec rankfile option right.
I would appreciate any help to solve the problem.
Also is there a way to tell Open MPI to print out its own numbering
of the "slots", and perhaps how they're mapped to the socket:core pair?
I am using Open MPI 1.4.

Understood - just pointing out that this is an error, even though w

I can successfully run the MPI testcode via OpenMPI 1.3.3 on less than 87 slots
w/both the btl_tcp_if_exclude and btl_tcp_if_include switches
passed to mpirun.
SGE always allocates the qsub jobs from the 24 slot nodes first -- up to the 96

I'm having a problem using OpenMPI under PBS Pro 10.4. I tried both 1.4.3 and
1.5.3, both behave the same. I'm able to run just fine if I don't use PBS and
go direct to the nodes. Also, if I run under PBS and use only 1 node, it works
fine, but as soon as I span nodes, I get the following:

A few thoughts:
* including both btl_tcp_if_include and btl_tcp_if_exclude is problematic as
they are mutually exclusive options. I'm not sure which one will take
precedence. I would suggest only using one of them.
* the default mapping algorithm is byslot - i.e., OMPI will place procs on each
Please help me resolve the following problems with a 306 node Rocks cluster
