Cplant Release 0.4 Notes

Cplant Release 0.4

November 22, 1999

This release of Cplant software adds support for the Portable Batch System (PBS) queueing system, and also includes support for extending the parallel I/O capabilities of a cluster. PBS has been integrated into the Cplant runtime environment to provide a queueing system that can be used to submit and monitor batch jobs. The parallel I/O capabilities have been extended to include an I/O proxy mechanism that uses a third party vendor cluster filesystem (current SGI's CXFS on Alaska). We have also upgraded the Cplant software to support version 2.2.10 of the Linux kernel. This upgrade was required to support the FY99 Cplant hardware, Compaq XP1000 workstations. 580 of these workstations running Cplant software achieved 247.6 GFLOPS on MPLINPACK, which is #40 on the November 1999 list of the Top 500 supercomputers in the world. More information and documentation on these features will be available at the following Cplant web site.
