Hi all,
I have been tracking down a problem with resuming a few benchmarks which
include (fma3d, ammp, apsi, mgrid, and others) at certain checkpoints.
The culprit appears to be a sqrtt (FloatSqrt) operation that gets stuck
at the head of the queue and stalls the detailed model (O3CPU). If I run
the benchmark in AtomicSimpleCPU there is no problem. I have confirmed
that sqrtt is at the head of the queue in four samples (two in ammp and
two in apsi). The simulation ends with ("Exiting @ cycle
9223372036854775807 because simulate() limit reached.") . The same
symptoms are seen in other benchmarks suffering a similar phenomena and
I guess that sqrtt may also be the culprit. If anyone has some insight
on what might be happening, it would be appreciated.
