Deadline for TreeThreader
We adjusted the deadline several times for TreeThreader upon requests from volunteers. But due to the specific setup on the frontend server of TreeThreader which generate and submit jobs to CAS@home, this application needs a tighter deadline. The frontend server allows maximum 300 batches (9600 jobs) to run on CAS@home in parallel, so if the deadline is too loose, some batches do not get return in time and it will prevent the frontend server from submitting new jobs to CAS@home server. This leaves the fast voluteer hosts in a starving situation. To resolve this paradox, we examine the running time of all finished jobs of TreeThreader, and reach a conclusion that 98% jobs require less than 4.16hours on an average host and the longest running time job is 26.1hours on an exremely slow host (0.7GFLOS/s). Based on above analysis, we reset the TreeThreader job deadline to be 36hours. Please leave your feedback here if any exceptions happen on your host. Thanks!
