More documentation at http://gem5.org/Simpoints

Steps to profile, generate, and use SimPoints with gem5:

1. To profile workload and generate SimPoint BBV file, use the
following option:

--simpoint-profile --simpoint-interval <interval length>

Requires single Atomic CPU and fastmem.
<interval length> is in number of instructions.

2. Generate SimPoint analysis using SimPoint 3.2 from UCSD.
(SimPoint 3.2 not included with this flow.)

3. To take gem5 checkpoints based on SimPoint analysis, use the
following option:

--take-simpoint-checkpoint=<simpoint file path>,<weight file
path>,<interval length>,<warmup length>

<simpoint file> and <weight file> is generated by SimPoint analysis
tool from UCSD. SimPoint 3.2 format expected. <interval length> and
<warmup length> are in number of instructions.

4. To resume from gem5 SimPoint checkpoints, use the following option:

--restore-simpoint-checkpoint -r <N> --checkpoint-dir <simpoint
checkpoint path>

<N> is (SimPoint index + 1). E.g., "-r 1" will resume from SimPoint
#0.
