Grand Unified Python Benchmarks evaluation
Hello,
This is Catalin from the Server Scripting Languages Optimization Team at Intel Corporation. I tried doing an initial evaluation of FatPython's current performance on the Grand Unified Python Benchmarks (located at https://hg.python.org/benchmarks/). I encountered the following issues:
- I had to patch fatoptimizer because it failed when running any benchmark (I'm attaching the patch, the error was that callsite doesn't have a member called starargs or kwargs in some cases : fatoptimizer_gupb_compat.patch.zip)
- I had to patch perf.py from the benchmarks repository because not all benchmarks will work (currently 37/43, patch is also attached : gupb_fatpython_compat.patch.zip).
- Benchmarks not working:
- 2to3
- chameleon_v2
- tornado_http
- django_v3
- normal_startup
- startup_nosite
Revisions
- GUPB: 9923b81a1d34 + patch
- Baseline CPython 3: 0f46c9a5735f
Hardware and OS Configuration
- Platform: Intel XEON (Haswell-EP) 18 Cores
- BIOS settings:
- Intel Turbo Boost Technology: false
- Hyper-Threading: false
- OS: CentOS 7.1.1503
- OS configuration:
- Address Space Layout Randomization (ASLR) disabled to reduce run to run variation by
echo 0 > /proc/sys/kernel/randomize_va_space - CPU frequency set fixed at 2.3GHz
- Address Space Layout Randomization (ASLR) disabled to reduce run to run variation by
- GCC version: 4.8.3
Running GUBP
The command used for running GUBP was:
python perf.py /path/to/baseline/python /path/to/fatpython/fatpython -b all -r --csv outfile.csv --affinity 6
fatpython is a shell script that contains the following two lines:
#!/bin/bash
/absolute/path/to/fatpython/python -X fat "$@"
