Hi Richard -- This was reported to us internally. The performance of this test
case on a P8 server indicates that disabling complete unrolling and applying
unroll-and-jam could produce about a 1.5x speedup. I am going to have our
performance team verify that this is the case using just the options that Li
Jia used; the original report modified the source to provide the results of
unroll-and-jam since the reporter didn't know how to disable cunrolli. I'll
post the results here when we have them.
