+h3(#InstanceTypes). InstanceTypes: Avoid submitting jobs with unsatisfiable resource constraints
+
+LSF does not provide feedback when a submitted job's RAM, CPU, or disk space constraints cannot be satisfied by any node: the job will wait in the queue indefinitely with "pending" status, reported by Arvados as "queued".
+
+As a workaround, you can configure @InstanceTypes@ with your LSF cluster's compute node sizes. Arvados will use these sizes to determine when a container is impossible to run, and cancel it instead of submitting an LSF job.
+
+Apart from detecting non-runnable containers, the configured instance types will not have any effect on scheduling.
