The general characteristics are: 55 ns clock 64-bit architecture 64 or 128 MB memory 80 ns DRAM 576 MB/s bandwidth 4 memory ports (2 read, 1 write, 1 i/o) VME I/O subsystem 36 MFLOPS peak (100x100 is 9, 1000x1000 is 34) >Ditto for the YMP/EL. The YMP/EL has not, as of yet, been officially announced, but here are some specs which have been provided in the past: 30 ns clock 64-bit vector, Y-MP campatable 256 to 1024 MB memory 1 GB/sec bandwidth per CPU 1 to 4 CPUs 4 memory ports The rest will be available at time of announcement > >Thanks! > You're welcome! -- ******************************************************************************* * Dennis Ellis (dre@sequoia.cray.com) * * * Cray Research, Inc. * * * Eagan, MN 55121 * All the normal stuff about opinions.. *
