Note in the case of execution on a JVM, a single process will be spawned with P places. In the case of native execution, each place will be executed in a separate process. The nodes on which the processes are spawned is determined by the hosts file.
Also setting the number of initial threads in a place is important. When using mpirun, please use the -x option to set the X10_NTHREADS variable, thus: mpirunx10 -x X10_NTHREADS=<n> -np <p> --hostfile <hostfilename> <x10executable> <program args> Igor Peshansky wrote: > Kshitij Mehta <kvm1...@gmail.com> wrote on 11/10/2009 01:08:14 PM: > > >> Hello >> Is there a way to set the no. of places in the Linux environment? >> Looks like the default value is 4, which was set by the x10 runtime >> during installation.
