I used to be able to set this to specify the number of Parallel Tasks.
I still can with 1.20.
With 1.22, it says that this is an illegal lvalue. And the documentation
agrees saying I can only query this variable.
What is the mechanism to force the maximum parallelism achievable on a
given machine please? I went fishing in the documentation and cannot find
anything.
I do notice now that serial now only ever uses 100% of a CPU so I no
longer need to use this to single single CPU mode.
I want this to be able to test code on say an N-core machine with say
N/4 cores
N/2 cores
N cores
active in my Chapel task.
