+Description:  Benchmarks a disk with multithreaded I/O.
+
+Usage:  diskbench.sh path=<path> data=<8g> passes=<2> threads=<>
+
+Parameters:
+path=           Location to read and write.
+data=8g         Number of bytes to process per pass.
+threads=        Number of threads to use.  By default, all logical threads.
+                In RW mode the number of active threads is doubled.
+mode=rw         I/O mode:
+                   r:  Test read speed only.
+                   w:  Test write speed only.
+                   rw: Test read and write speed simultaneously.
+
+Processing parameters:
+None yet!
+
+Java Parameters:
+-Xmx            This will set Java's memory usage, overriding autodetection.
+                -Xmx20g will specify 20 gigs of RAM, and -Xmx200m will
+                specify 200 megs. The max is typically 85% of physical memory.
+-eoom           This flag will cause the process to exit if an out-of-memory
+                exception occurs.  Requires Java 8u92+.
+-da             Disable assertions.
+
+Please contact Brian Bushnell at bbushnell@lbl.gov if you encounter any problems.
