TheCray J90series (code-namedJediduring development) was an air-cooledvector processorsupercomputerfirst sold byCray Researchin 1994. The J90 evolved from theCray Y-MP ELminisupercomputer, and is compatible with Y-MP software, running the sameUNICOSoperating system. The J90 supported up to 32CMOSprocessors with a 10 ns (100 MHz) clock. It supported up to 4 GB of mainmemoryand up to 48 GB/s of memory bandwidth, giving it considerably less performance than the contemporaryCray 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 on theVME64bus andSPARCI/O processors (IOPs) running theVxWorksRTOS. The IOS was programmed to emulate the IOS Model E, used in the largerCray Y-MPsystems, in order to minimize changes in the UNICOS operating system. By using standard VME boards, a wide variety of commodity peripherals could be used.
The J90 was available in three basic configurations, theJ98with up to eight processors, theJ916with up to 16 processors, and theJ932with up to 32 processors.
Each J90 processor was composed of two chips - one for the scalar portion of the processor, and the other for the vector portion. The scalar chip was also notable for including a small (128 word)data cacheto enhance scalar performance. (Cray machines have always had instruction caching.)
In 1997 theJ90se(Scalar Enhanced) series became available, which doubled the scalar speed of the processors to 200 MHz; the vector chip remained at 100 MHz. Support was also added for the GigaRing I/O system found on theCray T3EandCray SV1, replacing IOS-V. Later,SV1processors could be installed in a J90 or J90se, further increasing performance within the same frame.
