BoilerGrid Overview

BoilerGrid was a large, high-throughput, distributed computing system operated by ITaP, and used the HTCondor system developed by the HTCondor Project at the University of Wisconsin. BoilerGrid provided a way for you to run programs on large numbers of otherwise idle computers in various locations, including any temporarily under-utilized high-performance cluster resources as well as some desktop machines not currently in use.

Whenever a local user or scheduled job needs a machine back, HTCondor stopped its job and sent it to another HTCondor node as soon as possible. Because this model limits the ability to do parallel processing and communications, BoilerGrid was only appropriate for relatively quick serial jobs.

BoilerGrid scavenged cycles from many ITaP research systems. BoilerGrid also used idle time of machines around the Purdue West Lafayette campus. Whenever the primary scheduling system on any of these machines needed a compute node back or a user sat down and started to use a desktop computer, HTCondor would stop its job and, if possible, checkpointed its work. HTCondor then immediately tried to restart this job on some other available compute node in BoilerGrid.

BoilerGrid used HTCondor 7.8.7.
