Directive to run once on every node? #5

Closed dylex closed 7 years ago

To prepare an environment, for example.

You might also imagine a per-node barrier, to allow such a thing to run before other tasks on that node, but not block other nodes.

DISBATCH PERNODE submits a task to run once on each node, but which otherwise acts like a normal (repeat) task. No node barrier (yet).
