Online Data Challenge 2013 Log
From GlueXWiki
Here is a record of the Hall-D Online Data Challenge Exercise done in the Hall-D Counting House August 26-29.
August 26, 2013
- Today was spent finalizing some setup including a number of scripts to start and stop processes on multiple systems
- We also finished getting Sean registered and issued a badge so that he has access to the counting house un-escorted

Executing run plan:
1. Start/stop scripts verified and are now in routine use. We noticed that ET systems can often leave system in a state that makes it hard to restart properly. The speculation is that the et system file is not actually being deleted and restarting tries to use this (unsuccessfully). Start/stop scripts updated to remove et system file just before starting system.
2. 100Hz ran fine. CPU on all nodes maxed out because of JANA spinning when starved for events rather than sleeping.
