Hello,

I tried the following to place LAM-MPI tasks on an SMP system.

lamboot -v -ssi rpi usysv ./hostfile

with cat ./hostfile
toto cpu=16

Then I tried to launch an application
mpirun c8-15 ./a.out

But it did not work, LAM-MPI tasks were not running on cpus 8-15.

Did I do something wrong?
Does LMA-MPI placement work on SMP system?

I am using lam-7.1.2

Charles
