- * "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.

- * NOTE
- * * Crystal changed from 'stock' to listed value.
- * + This Macintosh was upgraded from 128K to 512K in such a way that
- * the new 384K of memory is not slowed down by video generator accesses.
- * % Single processor; MC == MASSCOMP
- * NM A version 7 C compiler written at New Mexico Tech.
- * @ vanilla Lattice compiler used with MicroPro standard library
- * S Shorts used instead of ints
- * T with Chris Torek's patches (whatever they are).
- * ~ For WICAT Systems: MB=MultiBus, PB=Proprietary Bus

- * CT1 Convergent Technologies MegaFrame, 1 processor.
- * MN Using Mike Newtons 'optimizer' (see net.sources).
- * G1 This Gould machine has 2 processors and was able to run 2 dhrystone
- * Benchmarks in parallel with no slowdown.
- * FH FHC == Frank Hogg Labs (Hazelwood Uniquad 2 in an FHL box).
- * FX The Alliant FX/8 is a system consisting of 1-8 CEs (computation
- * engines) and 1-12 IPs (interactive processors). Note N8 applies.
- * RT This is one of the RT's that CMU has been using for awhile. I'm
- * not sure that this is identical to the machine that IBM is selling
- * to the public.
- * i1 Normally, the 386/20 starter kit has a 16k direct mapped cache
- * which inserts 2 or 3 wait states on a write thru. These results
- * were obtained by disabling the write-thru, or essentially turning
- * the cache into 0 wait state memory.
- * Nnn This machine has multiple processors, allowing "nn" copies of the
- * benchmark to run in the same time as 1 copy.
- * &nn This machine has "nn" processors, and the benchmark results were
- * obtained by having all "nn" processors working on 1 copy of dhrystone.
- * (Note, this is different than Nnn. Salesmen like this measure).
- * ? I don't trust results marked with '?'. These were sent to me with
- * either incomplete info, or with times that just don't make sense.
- * ?? means I think the performance is too poor, ?! means too good.
- * If anybody can confirm these figures, please respond.

- *--------------------------------RESULTS END----------------------------------
- *
- * The following program contains statements of a high-level programming
- * language (C) in a distribution considered representative:
- *
- * assignments 53%
- * control statements 32%
- * procedure, function calls 15%
- *
- * 100 statements are dynamically executed. The program is balanced with
- * respect to the three aspects:
- * - statement type
- * - operand type (for simple data types)
- * - operand access
- * operand global, local, parameter, or constant.
- *
- * The combination of these three aspects is balanced only approximately.
- *
- * The program does not compute anything meaningfull, but it is
- * syntactically and semantically correct.
