Sorry, there was a miscommunications between Ethan and I. The "*"
nomenclature never worked in OMPI, it is the specification of "n:*" that
works and we believe still works.

It looks like the rankfile "*" syntax was broke between version r22761
and r23214. So, it looks like a regression to me. Ethan is looking
into trying to narrow this down more.

I would have to look at the code, but I suspect it doesn't handle "*". Could be
upgraded to do so, but that would depend on the relevant developer to do so :-)

Thanks a lot, it works fine for me.
But going back to my problems - is it some bug in open-mpi or I should
use "slot=*" option in some other way?

I would recommend using the sequential mapper instead:
mpirun -mca rmaps seq
You can then just list your hosts in your hostfile, and we will put the ranks
sequentially on those hosts. So you get something like this
host01 <= rank0
host01 <= rank1
host02 <= rank2
host03 <= rank3
host01 <= r
In my previous mail I said that slot=0-3 would be a solution.
Unfortunately it gives me exactly the same segfault as in case with
*:*

Hi,
I'd like mpirun to run tasks with specific ranks on specific hosts,
but I don't want to provide any particular sockets/slots/cores.
The following example uses just one host, but generally I'll use more.
In my hostfile I just have:
root@host01 slots=4
I was playing with my rankfile to achieve
