Setting Up the Simulation Infrastructure:
1. Download the BPC kit:
bpc6421AU17.zip (~500M) and save it in your home directory.
2. Unpack the kit:
gunzip bpc6421AU17.zip cd bpc6421AU17
3. There should be four directories: sim, scripts, traces, and results
4. The sim directory contains the simulator.
cd sim make
./predictor ../traces/SHORT-INT-1.cbp4.gz
5. The scripts directory contains scripts that can help you run your predictor for all traces. Check out the doit.sh file in the scripts directory.
cd ../scripts
./doit.sh
6. We will use the AMEAN over all traces as the figure of merit. You can compute this using the getdata.pl script. Usage is as follows.
./getdata.pl -d ../results/GSHARE*
7. The traces directory contains 20 traces: 10 short traces (~30 million instructions) derived from CBP-1 and 10 long traces(~150 million instructions) derived from SPEC 2006.
Writing Your Own Branch Predictor:
In your sim directory, there are two files you can modify: predictor.cc and predictor.h
Only these two files should be submitted with your contest submission. Any changes you make to any other files will not be reflected in our simulator.
