This log contains 11 days of activity from multiple nodes that make up the LCG (Large Hadron Collider Computing Grid). Users submit serial or parallel jobs to resource brokers. The resource brokers find suitable resources for carying out the computation, and send processes for execution on the different systems. The log is at the level of individual processes, and does not contain data about which processes may be part of the same parallel job. A side effect is that all jobs (actually processes) are recorded as having a size of 1. For more information about this installation, see the LCG website.
