+This package includes five tools:
+sgpdd-survey:
+A test of the 'bare metal' performance, bypassing as much of the kernel as we can. Uses the sgp_dd utility.
+
+obdfilter-survey
+This survey can be run in 3 modes to test disk I/O including the filesystem,
+network I/O, and disk I/O via the network. The script does sequential I/O
+with varying numbers of threads and objects (files) by using lctl::test_brw
+to drive the echo_client connected to local or remote obdfilter instances,
+or remote obdecho instances.
+
+ost-survey
+This survey tests the client-to-disk performance of individual OSTs, and
+ranks then for comparison.
+
+stats-collect
+This script will collect IO stats on a defined set of nodes.
+
+ior-survey:
+A script to run the IOR benchmark. The latest version can be downloaded from http://www.llnl.gov/asci/purple/benchmarks/limited/ior/
