return to main page??? What is Dhrystone ??? ;-)) Dhrystone speed test
Feb 18, 2015
Robert Garner and Luca Severini were "shooting the breeze"
Robert said
"Yes, this is the Dhrystone version I was thinking of (which includes a table of results).
(This viewing caused &^%$#^ flashbacks -- I haven't seen this code listing since 1986!)
Good to hear it looks possible to run on our 1401.
(but no cheating. ;-)) "
Luca came back with
"Of course no cheating. Only tricks to make the code generated by the compiler smaller and faster... ;-) "
/***** hpda:net.sources / homxb!gemini / 1:58 am Apr 1, 1986*/ /* EVERBODY: Please read "APOLOGY" below. -rick 01/06/85 * See introduction in net.arch, or net.micro * * "DHRYSTONE" Benchmark Program * * Version: C/1.1, 12/01/84 * * Date: PROGRAM updated 01/06/86, RESULTS updated 03/31/86 * * Author: Reinhold P. Weicker, CACM Vol 27, No 10, 10/84 pg. 1013 * Translated from ADA by Rick Richardson * Every method to preserve ADA-likeness has been used, * at the expense of C-ness. * * Compile: cc -O dry.c -o drynr : No registers * cc -O -DREG=register dry.c -o dryr : Registers * * Defines: Defines are provided for old C compiler's * which don't have enums, and can't assign structures. * The time(2) function is library dependant; Most * return the time in seconds, but beware of some, like * Aztec C, which return other units. * The LOOPS define is initially set for 50000 loops. * If you have a machine with large integers and is * very fast, please change this number to 500000 to * get better accuracy. Please select the way to * measure the execution time using the TIME define. * For single user machines, time(2) is adequate. For * multi-user machines where you cannot get single-user * access, use the times(2) function. If you have * neither, use a stopwatch in the dead of night. * Use a "printf" at the point marked "start timer" * to begin your timings. DO NOT use the UNIX "time(1)" * command, as this will measure the total time to * run this program, which will (erroneously) include * the time to malloc(3) storage and to compute the * time it takes to do nothing. * * Run: drynr; dryr * * Results: If you get any new machine/OS results, please send to: * * ihnp4!castor!pcrat!rick * * and thanks to all that do. Space prevents listing * the names of those who have provided some of these * results. I'll be forwarding these results to * Rheinhold Weicker. * * Note: I order the list in increasing performance of the * "with registers" benchmark. If the compiler doesn't * provide register variables, then the benchmark * is the same for both REG and NOREG. * * PLEASE: Send complete information about the machine type, * clock speed, OS and C manufacturer/version. If * the machine is modified, tell me what was done. * On UNIX, execute uname -a and cc -V to get this info. * * 80x8x NOTE: 80x8x benchers: please try to do all memory models * for a particular compiler. * * APOLOGY (1/30/86): * Well, I goofed things up! As pointed out by Haakon Bugge, * the line of code marked "GOOF" below was missing from the * Dhrystone distribution for the last several months. It * *WAS* in a backup copy I made last winter, so no doubt it * was victimized by sleepy fingers operating vi! * * The effect of the line missing is that the reported benchmarks * are 15% too fast (at least on a 80286). Now, this creates * a dilema - do I throw out ALL the data so far collected * and use only results from this (corrected) version, or * do I just keep collecting data for the old version? * * Since the data collected so far *is* valid as long as it * is compared with like data, I have decided to keep * TWO lists- one for the old benchmark, and one for the * new. This also gives me an opportunity to correct one * other error I made in the instructions for this benchmark. * My experience with C compilers has been mostly with * UNIX 'pcc' derived compilers, where the 'optimizer' simply * fixes sloppy code generation (peephole optimization). * But today, there exist C compiler optimizers that will actually * perform optimization in the Computer Science sense of the word, * by removing, for example, assignments to a variable whose * value is never used. Dhrystone, unfortunately, provides * lots of opportunities for this sort of optimization. * * I request that benchmarkers re-run this new, corrected * version of Dhrystone, turning off or bypassing optimizers * which perform more than peephole optimization. Please * indicate the version of Dhrystone used when reporting the * results to me. * * RESULTS BEGIN HERE * *----------------DHRYSTONE VERSION 1.1 RESULTS BEGIN-------------------------- * * MACHINE MICROPROCESSOR OPERATING COMPILER DHRYSTONES/SEC. * TYPE SYSTEM NO REG REGS * -------------------------- ------------ ----------- --------------- * Apple IIe 65C02-1.02Mhz DOS 3.3 Aztec CII v1.05i 37 37 * - Z80-2.5Mhz CPM-80 v2.2 Aztec CII v1.05g 91 91 * - 8086-8Mhz RMX86 V6 Intel C-86 V2.0 197 203LM?? * IBM PC/XT 8088-4.77Mhz COHERENT 2.3.43 Mark Wiiliams 259 275 * - 8086-8Mhz RMX86 V6 Intel C-86 V2.0 287 304 ?? * Fortune 32:16 68000-6Mhz V7+sys3+4.1BSD cc 360 346 * PDP-11/34A w/FP-11C UNIX V7m cc 406 449 * Macintosh512 68000-7.7Mhz Mac ROM O/S DeSmet(C ware) 625 625 * VAX-11/750 w/FPA UNIX 4.2BSD cc 831 852 * DataMedia 932 68000-10Mhz UNIX sysV cc 837 888 * Plexus P35 68000-12.5Mhz UNIX sysIII cc 835 894 * ATT PC7300 68010-10Mhz UNIX 5.0.3 cc 973 1034 * Compaq II 80286-8Mhz MSDOS 3.1 MS C 3.0 1086 1140 LM * IBM PC/AT 80286-7.5Mhz Venix/286 SVR2 cc 1159 1254 *15 * Compaq II 80286-8Mhz MSDOS 3.1 MS C 3.0 1190 1282 MM * MicroVAX II - Mach/4.3 cc 1361 1385 * DEC uVAX II - Ultrix-32m v1.1 cc 1385 1399 * Compaq II 80286-8Mhz MSDOS 3.1 MS C 3.0 1351 1428 * VAX 11/780 - UNIX 4.2BSD cc 1417 1441 * VAX-780/MA780 Mach/4.3 cc 1428 1470 * VAX 11/780 - UNIX 5.0.1 cc 4.1.1.31 1650 1640 * Ridge 32C V1 - ROS 3.3 Ridge C (older) 1628 1695 * Gould PN6005 - UTX 1.1c+ (4.2) cc 1732 1884 * Gould PN9080 custom ECL UTX-32 1.1C cc 4745 4992 * VAX-784 - Mach/4.3 cc 5263 5555 &4 * VAX 8600 - 4.3 BSD cc 6329 6423 * Amdahl 5860 - UTS sysV cc 1.22 28735 28846 * IBM3090/200 - ? ? 31250 31250 * * *----------------DHRYSTONE VERSION 1.0 RESULTS BEGIN-------------------------- * * MACHINE MICROPROCESSOR OPERATING COMPILER DHRYSTONES/SEC. * TYPE SYSTEM NO REG REGS * -------------------------- ------------ ----------- --------------- * Commodore 64 6510-1MHz C64 ROM C Power 2.8 36 36 * HP-110 8086-5.33Mhz MSDOS 2.11 Lattice 2.14 284 284 * IBM PC/XT 8088-4.77Mhz PC/IX cc 271 294 * CCC 3205 - Xelos(SVR2) cc 558 592 * Perq-II 2901 bitslice Accent S5c cc (CMU) 301 301 * IBM PC/XT 8088-4.77Mhz COHERENT 2.3.43 MarkWilliams cc 296 317 * Cosmos 68000-8Mhz UniSoft cc 305 322 * IBM PC/XT 8088-4.77Mhz Venix/86 2.0 cc 297 324 * DEC PRO 350 11/23 Venix/PRO SVR2 cc 299 325 * IBM PC 8088-4.77Mhz MSDOS 2.0 b16cc 2.0 310 340 * PDP11/23 11/23 Venix (V7) cc 320 358 * Commodore Amiga ?
