Lustre Bottlenecks
When you upgrade new processors into a Lustre environment of petabytes of storage, the Beowulf roars with indigestion.
Today’s scientific applications demand that high-performance I/O be part of their operating environment. These applications access datasets of many gigabytes or terabytes, checkpoint frequently, and create large volumes of visualization data. Such applications are hamstrung by bottlenecks anywhere in the I/O path, including the storage hardware, file system, low-level I/O middleware, application-level interface, and in some cases the mechanism used for Grid I/O access.
