BBV Research
I've developed some tools for generating Basic Block Vectors as used
by the SimPoint analysis tool.
My paper that appears
in HiPEAC 2008 describes this work. The results
are validated against hardware performance counters on x86
Linux.
We are currently working on getting cross-platform SimPoints working for a
variety of platforms. The table below is a summary of our progress.
| Target Arch | Collected On | Tool Used | Benchmarks | Validated | Paper |
|---|
| x86 | x86 | Pin, Qemu, Valgrind | SPEC2k, SPEC2k6 | Y | HiPEAC08 |
| MIPS | x86 | Qemu | SPEC2k | N | |
| PPC | PPC | Valgrind | SPEC2k | N | |
| SPARC | x86 | Qemu | SPEC2k,SPEC2k6 | N | Summary |
Here are links to the various tools:
- PinPoints - this utility was not made by us, it
comes with
Pin
- valsim - generate BBVs using
valgrind
- qemusim - generate BBVs using
qemu
- dynsim - I worked on a
dyninst method of
doing this. It was way too resource intensive, but the code
is available in case you are curious.
Here are slowdown numbers for the various
tools

CPI Phase behavior plots for SPEC CPU benchmarks.
