Workshops/JobParallelism

@@ -6 +6 @@
 Job parallelism refers to jobs for which 2 or more processing units (or processors or cores) execute the given job's code instructions simultaneously - rather than sequentially.
 
-Your job may need more than one processor to finish in a timely manner - or possibly to finish at all.
+== Why is Job Parallelism important? ==
+Your job may need more than one processor to run more quickly - or in a timely manner - or possibly to finish at all in the allowed execution time limit. For time limits, see [wiki:cypress/about#SLURMresourcemanager SLURM (resource manager)].
