perftest-1.3a/0000777000115300004540000000000007666706563007141 5perftest-1.3a/README0000664000115300004540000001245307564504035007727 This directory contains programs that are part of the mpptest performance test suite. By default, they generate output for the C.It graphics program; the -gnuplot option will generate data for Gnuplot. Because of limitations of Gnuplot, the full generality of these commands is not supported when gnuplot output is selected. To build the programs, use configure. In many cases, all you need to do is invoke configure. If that doesn't work, use the following: MPICH: ./configure --with-mpich SGI MPI: ./configure --with-sgimpi IBM MPI ./configure --with-ibmmpi Others (assuming that your shell is csh or tcsh): setenv CC name-of-C-compiler for MPI programs setenv F77 name-of-Fortran-compiler for MPI programs setenv MPILIB name-of-mpi-library ./configure If you are cross-compiling, but you can run programs locally using a different compiler, add the following environment variables setenv TESTCC name-of-C-compiler-for-local-programs setenv TESTF77 name-of-Fortran-compiler-for-local-programs The programs that you want to run are mpptest and goptest. You can run these as you would any MPI program, or you can use the following scripts that will generate data automatically. To use these, you will also need to create a script that runs an MPI program with some arguments; samples are provided for IBM's MPI in mpirun.ibm . For MPICH, you may use the mpirun provided by MPICH. For a quick overview of the performance of your system, try mpirun -np 2 mpptest -logscale mpirun -np 16 mpptest -bisect -logscale (the latter assumes that you have 16 processors). Several scripts have been provided to generate data. The following two run mpptest and goptest with common options. runmpptest - point-to-point tests and collective as a function of data length rungoptest - collective as a function of the number of processes To get an idea about your system, do (assuming a 32 processor system) ./runmpptest -short -pair -blocking -givedy -gnuplot -fname pt2pt.mpl ./runmpptest -np 32 -bisect -short -blocking -gnuplot -fname bisect.mpl ./rungoptest -maxnp 32 -add -bcast -gnuplot -fname bcast.mpl (use -mpirunpgm ./mpirun.ibm to select an alternate mpirun program (mpirun.ibm in this case) ) Then gnuplot pt2pt.mpl gnuplot bisect.mpl gnuplot bcast.mpl will generate plots of the performance of MPI_Send/MPI_Recv, (point to point and bisection bandwidth) and MPI_Bcast. These routines may be used for additional testing. For example, ./runmpptest -long -pair -nonblocking -givedy -gnuplot -fname nbpt2pt.mpl will give the performance of the nonblocking MPI routines with long messages. The script basetest can be used to get common information about your system for both point-to-point and collective calls. It In addition, mpptest and goptest may be used alone. Both take -help and give a summary of options. For example, ./mpptest -sz 2 -cachesize 1000000 causes the messages to be taken from a buffer of size 1000000, reducing the reuse of memory locations. The copytest program gives a rough estimate of how fast memcpy works in a single address space. To use mpirun -np 1 copytest This copies data from one place to another three times; the first copy may take longer because of the need to page in (and possibly initialize to zero) data. If the data cache is large enough, the second and third copies may be faster than expected. (You need to use mpirun because copytest uses MPI_Wtime to get times) Finally, the program buflimit is a simple program that estimates the size of message that you can send with an MPI_Send without having a matching receive. Just run mpirun -np 2 buflimit The following uses of runmpptest and rungoptest will produce a basic survey of your system. This script can be placed in a file and executed. -- cut here -- #! /bin/sh ./runmpptest -short -pair -blocking -givedy -gnuplot -fname pt2ptshort.mpl ./runmpptest -long -pair -blocking -givedy -gnuplot -fname pt2ptlong.mpl ./runmpptest -long -pair -nonblocking -givedy -gnuplot -fname nbpt2ptlong.mpl ./runmpptest -np 32 -bisect -short -blocking -gnuplot -fname bisectshort.mpl ./runmpptest -np 32 -bisect -long -blocking -gnuplot -fname bisectlong.mpl ./rungoptest -maxnp 32 -add -bcast -gnuplot -fname bcast.mpl temp=`which $gnuplot | head -1` if [ ! -x "$temp" ] ; then echo "Creating tar file of plot data" tar cf data.tar *.mpl *.??? else for file in *.mpl ; do filebase=`basename $file` # Use set terminal postscript eps # to get encapsulated Postscript for including in documents gnuplot <>${filebase}.ps set terminal postscript load $file EOF echo "Created file ${filebase}.ps" end fi -- cut here -- If you have access to the graphics program C.It (very few of you will), you can get slightly nicer output, as well as more easily getting "rate" graphs. To do this, do the following: Use -cit instead of -gnuplot as the option to mpptest. Add the -rate option to mpptest. For example, the basic performance plots for latency and bandwidth, using C.It output form, can be generated with mpirun -np 2 mpptest -cit -auto -autodx 4 > short.cit mpirun -np 2 mpptest -cit -rate -size 16000 1600000 16000 > long.cit Nonblocking versions are mpirun -np 2 mpptest -cit -async -auto -autodx 4 > short.cit mpirun -np 2 mpptest -cit -async -rate -size 16000 1600000 16000 > long.cit perftest-1.3a/stamp-h.in0000664000115300004540000000001207666706557010754 timestamp perftest-1.3a/Makefile.am0000664000115300004540000000257607353711272011107 # Process this file with automake to generate a Makefile.in # Automake controls AUTOMAKE_OPTIONS = foreign no-installinfo no-texinfo.tex ACLOCAL_AMFLAGS = -I config/confdb # Use AM_xFLAGS to modify compiler behavior AM_CFLAGS=${COPTIONS} # Package Description start here bin_PROGRAMS = mpptest goptest buflimit EXTRA_PROGRAMS = tunepkt pktuse copytest vectest stress ctest cluster tcomm EXTRA_SCRIPTS = rungoptest runmpptest runsample noinst_HEADERS = mpptest.h getopts.h extra_SOURCES = gopf.c grph.c ovlap.c pair.c pattern.c getopts.c \ rate.c mpe_seq.c copy.c mpptest_SOURCES = mpptest.c $(extra_SOURCES) halo.c goptest_SOURCES = goptest.c $(extra_SOURCES) vectest_SOURCES = vectest.f stress_SOURCES = stress.c daytime.c getopts.c tcomm_SOURCES = tcomm.c mpe_seq.c getopts.c copytest_SOURCES = copytest.c duff.c # Distribution modifications EXTRA_DIST = config ${EXTRA_SCRIPTS} # # Autoconf/make oftens find the wrong versions of autoconf/make/header/local dist-hook: -find ${distdir} -name CVS -print | sed 's/^/rm -rf /g' | sh cd ${distdir} ; sed -e 's/^AUTOMAKE.*/AUTOMAKE = true/g' \ -e 's/^AUTOCONF *=.*/AUTOCONF = true/g' \ -e 's/^AUTOHEADER *=.*/AUTOHEADER = true/g' \ -e 's/^ACLOCAL *=.*/ACLOCAL = true/g' Makefile.in > .tmp ; \ rm -f Makefile.in ; \ mv .tmp Makefile.in distclean-local: rm -f config.system clean-local: rm -f ${EXTRA_PROGRAMS} rm -f work.pc work.pcl perftest-1.3a/Makefile.in0000664000115300004540000003571307666706563011135 # Makefile.in generated automatically by automake 1.4 from Makefile.am # Copyright (C) 1994, 1995-8, 1999 Free Software Foundation, Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. # Process this file with automake to generate a Makefile.in # Automake controls SHELL = @SHELL@ srcdir = @srcdir@ top_srcdir = @top_srcdir@ VPATH = @srcdir@ prefix = @prefix@ exec_prefix = @exec_prefix@ bindir = @bindir@ sbindir = @sbindir@ libexecdir = @libexecdir@ datadir = @datadir@ sysconfdir = @sysconfdir@ sharedstatedir = @sharedstatedir@ localstatedir = @localstatedir@ libdir = @libdir@ infodir = @infodir@ mandir = @mandir@ includedir = @includedir@ oldincludedir = /usr/include DESTDIR = pkgdatadir = $(datadir)/@PACKAGE@ pkglibdir = $(libdir)/@PACKAGE@ pkgincludedir = $(includedir)/@PACKAGE@ top_builddir = .

The problem is dnl that the cache is read dnl without any check for whether it makes any sense to read it. dnl A common problem is a build on a shared file system; connecting to dnl a different computer and then building within the same directory will dnl lead to at best error messages from configure and at worse a build that dnl is wrong but fails only at run time (e.g., wrong datatype sizes used). dnl Later versions of autoconf do include some checks for changes in the dnl environment that impact the choices, but still misses problems with dnl multiple different systems. dnl dnl This fixes that by requiring the user to explicitly enable caching dnl before the cache file will be loaded. dnl dnl To use this version of 'AC_CACHE_LOAD', you need to include dnl 'aclocal_cache.m4' in your 'aclocal.m4' file. The sowing 'aclocal.m4' dnl file includes this file. dnl dnl If no --enable-cache or --disable-cache option is selected, the dnl command causes configure to keep track of the system being configured dnl in a config.system file; if the current system matches the value stored dnl in that file (or there is neither a config.cache nor config.system file), dnl configure will enable caching. In order to ensure that the configure dnl tests make sense, the values of CC, F77, F90, and CXX are also included dnl in the config.system file. dnl dnl Bugs: dnl This does not work with the Cygnus configure because the enable arguments dnl are processed *after* AC_CACHE_LOAD (!).

Only round trip available. Note that even blocking operations may have effective overlap, since all "blocking" refers to is the state of the buffer, not whether the message has been delivered. Modeling of the overlap This is much more difficult that modeling the send and receive, in part because two operations can be taking place at the same time. The easiest model assumes that the computation takes place only when the communication would be waiting. In this case, the computation is free until it uses up the idle time, when it switches to the "usual" cost of a floating point computation. This model, for fixed message length n, has constant time for m < Mcrit, and slope given by the floating point speed for the operation. for m > Mcrit. A more realistic model assumes that both operations impact the other, without requiring that the sum of the times have any particular relationship. For example, the loads and stores of the two operations may take place in each others memory-miss cycles, possible causing both to slow down a little. In this model, there are two positive slopes for the time, with a change at m == Mcrit (that is, at a time when the floating point operation has not finished by the time that the message has been completely sent). *****************************************************************************/ void SetupOverlap( int, OverlapData *), OverlapComputation( int, OverlapData *); void *OverlapInit( int proc1, int proc2, int size ) { OverlapData *new; new = (OverlapData *)malloc(sizeof(OverlapData)); if (!new) return 0;; new->proc1 = proc1; new->proc2 = proc2; new->MsgSize = size; new->Overlap1 = 0; new->Overlap2 = 0; new->OverlapSize = 0; new->OverlapLen = 0; new->OverlapPos = 0; return new; } /* Compute floating point lengths adaptively */ void OverlapSizes( int msgsize, int svals[3], void *vctx ) { double time_msg, time_float, tmp; int float_len; int saved_msgsize; OverlapData *ctx = (OverlapData *)vctx; if (msgsize < 0) { return; } saved_msgsize = ctx->MsgSize; ctx->MsgSize = msgsize; /* First, estimate the time to send a message */ time_msg = round_trip_b_overlap(100,0,ctx) / 100.0; MPI_Allreduce(&time_msg, &tmp, 1, MPI_DOUBLE,MPI_MAX,MPI_COMM_WORLD ); memcpy(&time_msg,&tmp,(1)*sizeof(double));; /* printf( "Time_msg is %f\n", time_msg ); */ float_len = msgsize; if (float_len <= 0) float_len = 32; /* Include the time of the message in the test... */ do { float_len *= 2; time_float = round_trip_b_overlap(100,float_len,ctx) / 100.0; MPI_Allreduce(&time_float, &tmp, 1, MPI_DOUBLE,MPI_MAX,MPI_COMM_WORLD ); memcpy(&time_float,&tmp,(1)*sizeof(double));; /* printf( "Time_float(%d) is %f\n", float_len, time_float ); */ } while (time_float < 2 * time_msg); svals[1] = float_len; svals[2] = (float_len - svals[0]) / 64; ctx->MsgSize = saved_msgsize; } /* Nonblocking round trip with overlap.
