Either request fewer procs for your application, or make more slots | |
available for use. | |
A "slot" is the PRRTE term for an allocatable unit where we can | |
launch a process. The number of slots available are defined by the | |
environment in which PRRTE processes are run: | |
1. Hostfile, via "slots=N" clauses (N defaults to number of | |
processor cores if not provided) | |
2. The --host command line parameter, via a ":N" suffix on the | |
hostname (N defaults to 1 if not provided) | |
3. Resource manager (e.g., SLURM, PBS/Torque, LSF, etc.) | |
4. If none of a hostfile, the --host command line parameter, or an | |
RM is present, PRRTE defaults to the number of processor cores | |
In all the above cases, if you want PRRTE to default to the number | |
of hardware threads instead of the number of processor cores, use the | |
--use-hwthread-cpus option. | |
Alternatively, you can use the --map-by :OVERSUBSCRIBE option to ignore the | |
number of available slots when deciding the number of processes to | |
launch. | |
