Hi,
I have one more problem with process bindings (both machines use
Solaris 10 with Sparc processors).
tyr hello_1 149 which mpicc
/usr/local/openmpi-1.7.4_64_cc/bin/mpicc
tyr hello_1 150 mpicc environ_mpi.c
tyr hello_1 151 mpiexec -np 2 --host rs1 a.out
tyr hello_1 152
Do you have any ideas

That would mean that a hostfile has nothing to do with the underlying
hardware and that it wo
As I said, in the absence of a hostfile, -host assigns ONE slot for each time a
host is named. So the equivalent hostfile would have "slots=1" to create the
same pattern as your -host cmd line.

Hi,
I thought that "slot" is the smallest manageable entity so that I
must set "slot=4" for a dual-processor dual-core machine with one
hardware-thread per core. Today I learned about the new keyword
"sockets" for a hostfile (I didn't find it in "man orte_hosts").
How would I specify a system with

Hi,
I recognized another problem with procecss bindings. The command
works, if I use "-host" and it breaks, if I use "-hostfile" with
the same machines.
tyr fd1026 178 mpiexec -report-bindings -host sunpc0,sunpc1 -np 4 \
-cpus-per-proc 2 -bind-to-core hostname
sunpc1
