SPEC has determined that this result was not in compliance with the SPEC
MPI2007 run and reporting rules. Specifically, the result did not meet the
requirement for baseline optimization flags to not use assertion flags (the
flag -fno-alias is a violation of this rule). The result was found to be
performance neutral compared to runs without -fno-alias. Replacement
results could not be produced because of system access limitations.
