Steps to Reproduce:
(You may need a beaker machine.)
1 yum install -y kernel-kernel-infiniband-stream

2 cd /mnt/tests/kernel/infiniband/stream

3 make (after the stream_c.exe build, kill make. We only need stream_c.exe, it is unnecessary to wait make exit.)

STREAM version $Revision: 5.9 $

This system uses 8 bytes per DOUBLE PRECISION word.
-------------------------------------------------------------
Array size = 200000000, Offset = 0
Total memory required = 4577.6 MB.
Each test is run 10 times, but only
the *best* time for each is used.
-------------------------------------------------------------
Printing one line per active thread....
-------------------------------------------------------------
Your clock granularity/precision appears to be 1 microseconds.
Each test below will take on the order of 304234 microseconds.
   (= 304234 clock ticks)
Increase the size of the arrays if this shows that
you are not getting at least 20 clock ticks per test.
-------------------------------------------------------------
WARNING -- The above is only a rough guideline.
For best results, please be sure you know the
precision of your system timer.
