Or you could just do:
mpirun --slot-list 0-3 -np 4 hostname
That will put the four procs on the cpu numbers 0-3, which should all be on the
first socket

Agreed. "physical id : 0" on each of CPUs 0-3 from your /proc/cpuinfo output
confirms this.

in the "old" 1.4.x and 1.5.x, I achieved this by using rankfiles (see
FAQ), and it worked very well. With these versions, --byslot etc. didn't
work for me, I always needed the rankfiles. I haven't tried the
overhauled "convenience wrappers" in 1.6 that you are using for this
feature yet, but I
There are 2 physical processors, each with 4 cores (no hyperthreading).
I want to instruct openmpi to run only on the first processor, using 4 cores.
[hammond@node48 ~]$ cat /proc/cpuinfo
processor : 0
vendor_id : AuthenticAMD
cpu family : 16
model : 4
model name
Anne,
output from "cat /proc/cpuinfo" on your node "hostname" may help those trying
to answer.

I gather there are two sockets on this node? So the second cmd line is
equivalent to leaving "num-sockets" off of the cmd line?
I haven't tried what you are doing, so it is quite possible this is a bug.

Thanks!
Built the latest snapshot. Still getting an error when trying to run on only
one socket (see below): Is there a workaround?
[hammond@node65 bin]$ ./mpirun -np 4 --num-sockets 1 --npersocket 4 hostname

Jeff is at the MPI Forum this week, so his answers will be delayed. Last I
heard, it was close, but no specific date has been set.

When is the expected date for the official 1.6.1 (or 1.6.2 ?) to be
available ?

Hi,
For benchmarking, we would like to use openmpi with
--num-sockets 1
This fails in 1.6, but Bug Report #3119 indicates it is changed in
1.6.1.
Is 1.6.1 or 1.6.2 available in tar.gz form?
Thanks!
Anne
