mcv - mesh file converter SYNOPSIS
mcv [options] [imfile] [omfile] [oxfile] DESCRIPTION
The mcv program converts Scotch mesh files from and to other external file formats. File imfile is converted into mesh file omfile, with optional geometry data being put in geometry file oxfile, if it is available. When file names are not specified, data is read from standard input and written to standard output. Standard streams can also be explicitly represented by a dash '-'. When the proper libraries have been included at compile time, mcv can directly handle compressed meshes, both as input and output. A stream is treated as compressed whenever its name is postfixed with a compressed file extension, such as in 'brol.msh.bz2' or '-.gz'. The compres- sion formats which can be supported are the bzip2 format ('.bz2'), the gzip format ('.gz'), and the lzma format ('.lzma', on input only). OPTIONS
-h Display some help. -iifmt Set format of input mesh file, which can be: bnum Boeing-Harwell format. This is an elemental matrix format. Only square matrices are supported. In case the file contains sev- eral matrices, the num parameter allow the user to provide the index of the matrix to convert, starting from 0. When the num parameter is not set, it is assumed to be 0. s Scotch mesh format. -oofmt Set format of output mesh file, which can be: s Scotch mesh format. This is the only possible choice at the time being. -V Display program version and copyright. EXAMPLE

gomtst - compute statistics on sparse matrix orderings SYNOPSIS
gotst [options] [gfile] [ofile] [lfile] DESCRIPTION
The gotst program computes, in a sequential way, statistics on a sparse matrix ordering, such as fill-in, operation count, and separator tree parameters: minimum, maximum, average height and variance of its leaves. Source graph file gfile can only be a centralized graph file. File ofile represents the ordering of the symmetric sparse matrix the pattern of which is represented by gfile. The resulting statistics are stored in file lfile. When file names are not specified, data is read from standard input and written to standard output. Standard streams can also be explicitly represented by a dash '-'. When the proper libraries have been included at compile time, gtst can directly handle compressed graphs, both as input and output. A stream is treated as compressed whenever its name is postfixed with a compressed file extension, such as in 'brol.grf.bz2' or '-.gz'. The compression formats which can be supported are the bzip2 format ('.bz2'), the gzip format ('.gz'), and the lzma format ('.lzma', on input only). Since gotst performs sequentially the symbolic factorization of matrix gfile in order to compute fill-in and operation count numbers, this program can take a long time or even run out of memory, when applied to very large graphs.
