GrB-mxm-timer

A very simple timer for GrB_mxm that emulates a "k-hop" sequence of operations as in the TigerGraph Graph Database Benchmark.

Usage

Usage: GrB-mxm-timer [OPTION]...

Times the iteration of B = A*B

  -h, --help               Print help and exit
  -V, --version            Print version and exit
  -s, --scale=INT          Scale (log2 # vertices in A)  (default=`20')
  -e, --edgefactor=INT     Edge factor, so # edges = ef * 2^scale
                             (default=`8')
  -A, --A=FLOAT            R-MAT upper left quadrant probability
                             (default=`0.55')
  -B, --B=FLOAT            R-MAT upper right & lower left quadrant probability
                             (default=`0.1')
  -N, --noisefact=FLOAT    Noise factor on each recursion  (default=`0.1')

  -c, --b-ncols=INT        Number of columns in B  (default=`16')
  -C, --b-used-ncols=INT   Number of columns actually used in the initial B
                             (default=`1')
  -E, --b-nents-col=INT    Number of entries per column in the initial B
                             (default=`1')

  -k, --khops=STRING       Number of iterations / hops (can be a space-delim
                             list)  (default=`4')

      --NE-chunk-size=INT  Number of edges to generate in a chunk.
                             (default=`3000')
      --verbose[=INT]      Provide status updates via stdout.  (default=`1')

Building

This should build out of the box on a generic host system.

To run on the stationary core but call LucataGraphBLAS via the SC/GC interface, override LDLIBS and possibly LDFLAGS to point to your build.

To build completely as a MWX for the Gossamer cores, add similar overrides (as well as the compiler), and call make TARGET_MWX=1.
