High Quality Content by WIKIPEDIA articles! The Cray J90 series (code-named Jedi during development) was an air-cooled vector processor supercomputer first sold by Cray Research in 1994. The J90 evolved from the Cray Y-MP EL minisupercomputer, and is compatible with Y-MP software, running the same UNICOS operating system. The J90 supported up to 32 CMOS processors with a 10 ns (100 MHz) clock. It supported up to 4 GB of main memory and up to 48 GB/s of memory bandwidth, giving it considerably less performance than the contemporary Cray T90, but making it a strong competitor to other technical computers in its price range. All input/output in a J90 system was handled by an IOS (Input/Output Subsystem) called IOS Model V. The IOS-V was based around the VME64 bus and SPARC I/O processors (IOPs) running the VxWorks RTOS. The IOS was programmed to emulate the IOS Model E, used in the larger Cray Y-MP systems, in order to minimize changes in the UNICOS operating system. By using standard VME boards, a wide variety of commodity peripherals could be used.
