Enable task affinity in slurm.conf

[sjpb]

Currently there is no task launch plugin configured, which means srun's --cpu-bind option does not work.

See guidance under TaskPlugin on the slurm.conf manpage:

NOTE: It is recommended to stack task/affinity,task/cgroup together when configuring TaskPlugin, and setting TaskAffinity=no and ConstrainCores=yes in cgroup.conf. This setup uses the task/affinity plugin for setting the affinity of the tasks (which is better and different than task/cgroup) and uses the task/cgroup plugin to fence tasks into the specified resources, thus combining the best of both pieces.

The task launch plugin is configured:
slurm.conf : "TaskPlugin=task/affinity,task/cgroup",
cgroup.conf : "TaskAffinity=no ConstrainCores=yes"
but srun's --cpu-bind option does not work, and the job runs with only one CPU core。

info:
srun --cpu-bind=socket mpiexec -n 6 -genv I_MPI_DEBUG=4 /home/bt-mz.C.x

Has anyone ever encountered a similar problem, or what is the cause of this problem？
