The scheduling of Pipelines across nodes in a Snaplex is done based on the following criteria:
...
memory usage, active threads, CPU, and open file descriptors.
You can utilize the Snaplex-level slot count field to control distributing the Pipelines to the nodes. The default value for slot count is 4000 slots, which correspond to active threads on a Snaplex node. For each Pipeline being prepared, SnapLogic generates an estimate of the slots required for executing the Pipeline, assuming that each Snap in the Pipeline and its child Pipelines consume a single thread. The Pipeline runtime information dialog's Extra Details tab displays the estimate of the required slot count. To illustrate, if a Pipeline has 30 Snaps, and the Snaplex node has 3980 active threads, then the execution requests are Queued because sufficient slots are not available.
