Running Jobs with Task Geometry
Specifying task geometry allows you to group tasks of a
parallel job step to run together on the same node. Task geometry
allows for flexibility in how tasks are grouped for execution on system
nodes. You cannot specify the particular nodes that these groups run
on; the scheduler decides which nodes run the specified groupings.
Enforcing Resource Usage Limits for Parallel Tasks
A typical Platform LSF parallel job launches its tasks
across multiple hosts. By default you can enforce limits on the total
resources used by all the tasks in the job.
