Sunnyvale, California-based MasPar Computer Corp, preparing to announce its MP-2 machine, has souped up the input-output performance of the MP-1 family of massively parallel processor systems. The new product, SuperStripe I/O, consists of a new high-speed input-output channel, a 1Gb solid state store and a new high-performance disk array. The new subsystem is capable of up to 1G-byte per second of throughput to the processor array, achieved by extending the concept of disk striping to the input-output system. Data striping starts with the new 42 Series disk array, extends through the 200M-byte per second channel to the solid state store, which stripes data between multiple memory modules and any of the 16,384 processors in the MP-1. The 1Gb semiconductor store can be used to overlap compute and input-output operations, as a global shared memory for the processor array, or as a solid state disk alternative with standard Unix file structure. The input-output system transparently performs data manipulation to ensure that the proper data arrives at the right processor in the right format and the maximum speed of the input-output system. The Channel I/O Controller is $34,000, memory modules for it start at $35,000 for 32Mb, $72,000 for 128Mb. The new 42 Series MasPar Parallel Disk Array announced today supports the Network File System protocol and provides a Unix-compat ible file system that can be accessed directly from the MP-1 or from other systems on the network via Ethernet or FDDI. It comes in capacities up to 132Gb and through put speeds up to 72M-bytes per second. It starts at $185,000 with 11Gb and arrives later this quarter.
