The mpqcrun program simplifies running MPQC.

Description

The mpqcrun program simplifies the task of running MPQC on multiple input files. Although it was primarily designed to run the validation suite, mpqcrun, is general enough to be useful in other situations. If multiple nodes or processors are present, it can be used to manage multiple invocations of MPQC.

Running mpqcrun

mpqcrun takes the following command line options:

–mpqc path

The mpqc executable to use.

–objdir

Run the mpqc executable in the compile directory, rather than the install directory.

–small

Skip big runs in verification suite.

–nnodeperjob n

Run with n nodes per job. If this is nnode, use all available nodes.

–nprocpernode n

Run with n processes per node.

–nprocperjob n

Run with n processes per job. The default is to use all available processors.

–nthreadperproc n

Use n threads per process.

–threadgrp grp

Use the given threading layer.

grp=none

Use MPQC's default.

grp=proc

Do a single threaded run.

grp=posix

Use POSIX threads.

–messagegrp grp

Use the given communication layer.

grp=none

Use MPQC's default.

grp=proc

Does a single processor run.

grp=mpi

Use MPI.

–memorygrp grp

Use the given remote memory communication layer.

grp=none

Use MPQC's default.

grp=proc

Does a single processor run.

grp=mtmpi

Use multi-threaded MPI.

grp=armci

Use ARMCI.

–memorysize s

Use at most the specified amount of memory. Examples of valid values: 0 (=unlimited), 32000000, 32000KB 32MB, 0.032GB, 0.000032TB. The default is to assume an unlimited amount of memory.

–diskpath s

The location for temporary high-speed storage. Directory name should end in "/", for example: –diskpath="/scratch/evaleev/". By default temporary files will be written to the current working directory, i.e. ./ .

–disksize s

Use at most the specified amount of disk storage. See also –memorysize. The default is to assume an unlimited amount ofdisk storage.

–launch cmd

Use the given command to launch jobs. See below.

–nodefile file

Specifies a file listing nodes to use. Duplicated nodes are removed.

–nodes nodes

Specifies list of machines to use. A range of nodes can be given with two integers separated by a dash. Groups of nodes can be separated by a comma.

–nodename fmt

This is a format string that converts the node number to its name.

–seq regex

Run inputs matching reqex sequentially. This is useful when one input requires that another be run first, and more than one job is run at a time.

–exclude regex

Exclude files matching regex.

–readdir dir

Run mpqc on all files matching dir/*.in.

–inputprefix prefix

Prepend prefix to all input file names.

–outputprefix prefix

Prepend prefix to all output file names.

–count

Print the number of input files that would be run.

–printfiles

Print the list of input files that would be run.

–rerun

Overwrite output file, even if up-to-date.

–onlynew

Do not overwrite output file, even if not up-to-date.

–simpout

Do not append extra info like nnode to filename.

–uniqout

Generate unique output filenames.

–autoout

Generate output filenames by replacing the suffix with "out".

–verbose

Print out what action is to be taken on each file.

–debug

Don't actually run mpqc.

–help

Print the documentation.

The cmd given with the –launch option can contain special strings that will be substituted:

%MPQCRUNPROC%

Script to runs MPQC with the environment set up correctly.

%INPUT%

The input filename.

%OUTPUT%

The output filename.

%NPROC%

The number of processes to start.

%NODEFILE%

The name of a file containing the node names.

%CONFIGFILE%

The name of a file having lines of the form: node: command.

%IFHNFILE%

The name of a file having lines of the form: node ifhn=value.

%NODELIST%

A comma separated list of node names.

%MPQC%

The MPQC executable.

For these last two, if they are contained within square brackets and a substitution is not available, then everything within the the brackets is removed.

This argument will launch MPI jobs giving mpirun a nodefile.

  --launch "mpirun [-hf %NODEFILE%] -n %NPROC% %MPQC% -o %OUTPUT% %INPUT%"

This argument will launch MPI jobs giving mpirun list of hosts on the command line.

  --launch "mpirun [-H %NODELIST%] -n %NPROC% %MPQC% -o %OUTPUT% %INPUT%"
