mdtest-bw_scratch

mdtest filesystem metadata benchmark     Scheduling frequency: 6h , nodes=4:ppn=6:xe,walltime=00:55:00

This test will plot the file read and removal ops/sec from a 4 node (24 rank ) mdtest with 2000 files per rank (48kfiles ).  It runs in a couple minutes and gives a sanity check on the health and performance of the lustre metadata servers for scratch.  Each test does a fresh git pull of the code and builds it--also doing a quick basic test of the default programming environment.

Tests: lustre meta data service, scratch, default PrgEnv-cray with MPI
