LUSTRE HELPS POWER THIRD FASTEST SUPERCOMPUTER
The third fastest supercomputer in the world according to the 21st Top500 supercomputing list at Lawrence Livermore National Laboratory (LLNL) has been in General Availability Production since Oct. 1.
The 1,152 node, 11.2 teraflops peak, Multiprogrammatic Capability Cluster (MCR) integrates LLNL's Cluster High Availability Operating System (CHAOS) and Cluster File Systems Inc's Lustre File System to provide a powerful research platform, with some 20 million files and 115.2 trillion bytes (terabytes) of aggregate storage across 64 object storage targets, that has already made significant contributions to LLNL research in the fields of laser research, fluid dynamics, materials behavior and seismology. MCR achieves 7.643 teraflops per second sustained as measured by the Linpack benchmark and with 90 percent efficiency for capacity production jobs is considered the fastest Linux-based supercomputer in the world.
Deployed with CHAOS, the Lustre File System has achieved I/O performance in excess of 4 Gigabytes per second.
"We started science runs several months ago to leverage MCR's power not only for the science but also to achieve levels of system and I/O performance that we have never before been able to offer," said Brian Carnes, division leader of Services and Development. "The science run opportunity achieves results for our users and early return on investment by stabilizing the hardware, perfecting CHAOS and Lustre and optimizing scheduling and operation of the cluster."
"In CHAOS we add to or modify tools and capabilities that allow Linux to achieve this high level of performance, reliability and robustness for our scientific applications," said Robin Goldstone, group leader of production at Linux, LLNL.
"Our work with the LLNL team led by Terry Heidelberg (Deputy Leader of High-Performance Systems) has significantly accelerated the completeness and maturity of Lustre as a high-performance and highly scalable solution," said Dr. Peter J. Braam, president and chief technology officer of Cluster File Systems Inc. "We look forward to pushing the performance envelope even further to meet the demanding performance and scalability requirements that are key to achieving LLNL's mission today and into the future."
