At present, the BRL Super Computing Facility includes two High Speed Processors: a Cray X-MP4/8 operating in unclassi- fied mode and a Cray-2 operating in classified. Both sys- tems utilize the UNICOS 6.1.12 operating system and imple- ment Cray's Network Queing System (NQS) for batch processing and Data Migration (DM) software. The Cray X-MP/48 has four processors with an 8.5 nanosecond clock rate, 8 Million 64-bit words of main memory, and a 128 Million 64-bit word Solid State Disk (SSD) available to all through logical device caching and swap space. The clock rate enables the machine to operate in the range of 250 MFLOPS. There are approximately 40 Gigabytes of on-line mass storage, and interfaces to IBM 3480 and IBM 3420 mag- netic tape devices. Available applications software include: DISSPLA; DISSPOP; IMSL; MPGS; BRLCAD; PICSURE; ABAQUS; LINDO; MSC/NASTRAN; MSC/DYNA; MSC/PISCES; and LQGALPH. Available compilers include: CFT; CF77; Pascal; and C. The Cray X-MP/48 is available 24 hours per day, 365 days per year; however, it is not attended during evening or mid- night shifts on weekends or holidays. The Cray-2 has four processors operating with a 4.1 nanosecond clock rate. This machine has 256 Million 64-bit _________________________ The information in this section is provided in accor- dance with the copyright notice appearing at the front of this guide.

There are approximately 60 Gigabytes of on-line mass storage, and an interface to IBM 3480 magnetic tape and to a MASSTOR M860 robotic tape device. Available applications software include: DISPPLA; DISSPOP; IMSL; MPGS; BRLCAD; PICSURE; CAD- PAC; and GAMESS. Available compilers include: CFT; CF77; Pascal; SIMSCRIPT; and C. The Cray-2 is available and attended 24 hours a day, 7 days a week. _N_e_t_w_o_r_k _A_c_c_e_s_s The Cray X-MP is accessible via the Internet, and has dial- up accessibility. The Cray-2 occupies a node on the Defense Secure Network (DSNET), and has dial-up accessibility via Secure Telephone Units (STU-III). _W_h_o _C_a_n _U_s_e _B_R_L _R_e_s_o_u_r_c_e_s BRL resources are available to DOD Agencies and qualified Government Contractors. _M_i_s_c_e_l_l_a_n_e_o_u_s Further information about the Cray X-MP/48 is available by writing: Director US Army Ballistic Research Lab ATTN: SLCBR-SE-A (Denice Brown) Aberdeen Proving Ground, MD 21005-5066 or Phoning (410) 278-6269, or sending electronic mail to sys-admin-xmp.brl.mil (Internet) Further information about the Cray-2 is available by writ- ing: Director, US Army Ballistic Research Lab ATTN: SLCBR-SE-A (Mark Williams) Aberdeen Proving Ground, MD 21005-5066 or Phoning (410) 278-6664, or sending electronic mail to sys-admin-cray2.brl.mil (Internet) August 19, 1992 NNSC Section 1.11, Page 2
