The Cray XD1 was an entry-level supercomputer range, made by Cray Inc. The XD1 uses AMD Opteron 64-bit CPUs, and utilizes the Direct Connect Architecture over HyperTransport to remove the bottleneck at the PCI and contention at the memory. The MPI latency is ¼ that of Infiniband, and 1/30 that of Gigabit Ethernet. The XD1 was originally designed by OctigaBay Systems Corp. of Vancouver, British Columbia, Canada as the OctigaBay 12K system. The company was acquired by Cray Inc. in February 2004.

| - The Cray XD1 was an entry-level supercomputer range, made by Cray Inc. The XD1 uses AMD Opteron 64-bit CPUs, and utilizes the Direct Connect Architecture over HyperTransport to remove the bottleneck at the PCI and contention at the memory. The MPI latency is ¼ that of Infiniband, and 1/30 that of Gigabit Ethernet. The XD1 was originally designed by OctigaBay Systems Corp. of Vancouver, British Columbia, Canada as the OctigaBay 12K system. The company was acquired by Cray Inc. in February 2004. Announced on 4 October 2004, the Cray XD1 range incorporate Xilinx FPGAs for application acceleration. With 12 CPUs in a chassis, and up to 12 chassis installable in a rack, XD1 systems may hold several 144-CPU multiples in multirack configurations. The operating system used on the XD1 is a customized version of Linux, and the machine's load balancing / resource management system is an enhanced version of Sun Microsystems' Sun Grid Engine. (en)

La compagnia venne acquisita dalla Cray Inc. nel febbraio 2004. Presentato il 4 ottobre 2004 il Cray XD1 includeva una FPGA Xilinx Virtex-II per accelerare le applicazioni. Uno chassis poteva contenere 12 processori e 12 chassis potevano venir ospitati in un rack. Un sistema XD1 poteva accogliere più rack per espandere le prestazioni del sistema. Il sistema operativo dell'XD1 era una versione personalizzata di Linux e un gestore/bilanciatore di carico basato sul Sun Microsystems Grid Engine. (it)
