70 -- UPDATE VIA TRADE-IN FROM AN INTEL IPSC/860 COMPUTER TO A MASSIVELY PARALLEL PROCESSOR (MPP) Point of Contact is Captain Jeffery S. Dilbert, ASC/PKWRS, (513) 257-4522, or Michael W. Kachur, Contracting Officer, (513)257-4872. Wright Laboratory, located at Wright-Patterson Air Force Base OH, intends to purchase the following upgrade via trade-in from an Intel iPSC/860 computer to a massively parallel procesor (MPP) Paragon XP/E Supercomputer from the Intel Corporation, Scalable Systems Division, 131 National Business Parkway, Suite 200, Annapolis Junction, MD 20701. 1. HARDWARE REQUIRED: An MPP with mesh parallel architecture supporting 600 MFLOPS Peak 64 bit performance with 4.0 GBytes RAID mass storage and 8 16 MB GP compute nodes with 8 16MB daughterboards (256MBytes memory); one 16MB GP SCSI I/O node with 16MB daughterboard; one 16MB GP combination Ethernet and service node with 16MB daughterboard; one 4mm DAT backup tape drive and an external diagnostic station. The MPP must support the following operating system software: OSF/1 operating system, TCP/IP support, network file system, MACS resource control system and network queuing system (NQS). Also the MPP must support an optimized C compiler, an interactive parallel debugger, performance analysis tools, basic math library (BLAS 1.2.3 & FFT's), an assembler, linker, loader and object management tools. The MPP will support the Virtual Reality Laboratory housed within WL/MLPJ, building 651 in area B. The MPP is to serve as the numerical computation component of a heterogeneously hosted, virtual-reality based, real-time molecular docking facility. The MPP must be fully compatible with an optimized for the following software applications: GROMOS, CHARMm, AMBER and WESTDYN. The MPP must be capable of performing three types of computational updates; reactive force computation and control of a force-feedback system; high-resolution steroscopic image generation; and numeric computations of molecular force fields, energies, positions, and momenta of many thousands of atoms under computer simulation. The MPP must generate enough updates to the human operator of the force feedback arm to create the perception of smooth forces, namely of at least 20 updates per second (ups). Actual rates depend on the characteristics of the forces being probed, with rates exceeding 80 ups required to adequately simulate sharp onset forces. Perception of continous visual imagery requires a minimum of 24 frames (still images) per second (fps) which leads to a requirement of 48 fps for stereoscopic vision simulation. Molecular dynamics simulation imposes an additional 20-100 ups. 2. REQUIRED QUALIFICATIONS: Prospective sources must demonstrate hardware compatibility with GROMOS, CHARMm, AMBER and WESTDYN; the hardware must generate at a minimum 80 ups and be of a mesh parallel architecture; the hardware must exhibit complete hardware compatibility with the Intel iPCS/860, etc. Interested Sources may submit pricing and techical data. All responses received from responsible sources on or before 15 days from this publication will be fully considered. As a result of analyzing this synopsis of intent, the contracting officer may determine that a solicitation will be issued to the intended vendor and all firms that respond to this synopsis of intent or otherwise request a copy of the solicitation.
