Description
The Parallel ROOT Facility, PROOF, enables a physicist to analyze and
understand very large data sets on an interactive time scale. It makes use
of the inherent parallelism in event data and implements an architecture
that optimizes I/O and CPU utilization in heterogeneous clusters with
distributed storage. Scaling to many hundreds of servers is essential
to process tens or hundreds of gigabytes of data interactively. This is
supported by the industry trend to pack more CPU's into single systems and
to create bigger clusters by increasing the number of systems per rack. We
will describe the latest developments in PROOF and the development of a
standardized benchmark for PROOF clusters. The benchmark is self contained
and measures the network, the I/O and the processing characteristics of
a cluster. We will present the comprehensive results of the benchmark for
several clusters, demonstrating the performance and scalability of PROOF
on very large clusters.
