Berkley Shands The following is a floating point benchmark used by our group to rate CPU speed on a standard problem set in molecular modeling. The data set is the Angiotensin Converter Enzyme Inhibitors. The application is an in-house conformational search package written in C. The Rotatable bond scan factor is 4 degrees. Runtime summary of Constrained Search (CSR) V4.2 from The Center For Molecular Modeling, Washington University - St. Louis, Mo. Optimization level as indicated, single precision floating point when available. Micro-VAX-II runs VMS 5.3-2, all others are running some flavor of BSD or SYSV Unix. Single stream execution on multiprocessors. The SPARC machines used an aproximate square-root. All others used the standard system call. This is equivalent to a 20% speedup on SPARC machines. ******************************************************************************* CPU Secs X uVAXII CPU ======== ======== ========================= 289 35.98 33Mhz R3000 SGI 4d/380 -O2 378 27.51 24Mhz R3000 DECstation-5000/200 -O3 410 25.36 24Mhz R3000 ESV -O3 457 22.75 IBM R6000-320 Xcl -O (not fully optimized) 504 20.63 20Mhz R3000 Personal Iris -O3 592 17.56 16Mhz R3000 4d/80s Iris -O3 717 14.50 4/380 Sun Sparc -O4 857 12.13 12Mhz R2000 Personal Iris -O3 1017 10.22 Sun Sparcstation SLC -O4 1054 9.86 4/280 Sun Sparc -O4 2308 4.50 VAXStation 3520 10400 1.00 Micro-VAX-II *******************************************************************************
