Building PyPy for Win 64
by a sh Aug. 7, 2016

Aug. 7, 2016

Hi all, I'm a Java developer, testing the possibility of embedding PyPy in my code using JNI. In order to do so I need to build PyPy for Win 64. I am aware that it is not currently supported, but I figured I'd give it a shot, So I've tried building pypy2-v5.3.1-src on a Win 64 bit machine. (with Python 2.7 installed). Followed the instructions here http://doc.pypy.org/en/latest/windows.html and even managed to create a cygffi-6.dll However, attempting to build PyPy itself failed with … [View More]

NumPyPy vs NumPy
by Papa, Florin Aug. 5, 2016

Aug. 5, 2016

Hi, This is Florin Papa from the Dynamic Scripting Languages Optimizations Team at Intel Corporation. I have been working with NumPyPy to evaluate its performance and it seems significantly slower compared to CPython NumPy or even PyPy NumPy (installed with pip). The results were gathered after running microbenchmarks inspired from here: http://www.labri.fr/perso/nrougier/teaching/numpy.100/ These benchmarks perform basic tasks, such as matrix multiplication, generate Cauchy matrix, generate … [View More]

how to extend VTUNE support from pypy for application hot spot analysis
by Wang, Peter Xihong Aug. 4, 2016

Aug. 4, 2016

Hi, Armin created a minimum working version incorporating VTUNE to a branch at: https://bitbucket.org/pypy/pypy/branch/vtune This works in a sense such that statistically meaningful micro-architecture data could be collected. However, for hot spot analysis, we'd like to trace back to the Python application source code. We know the VTUNE hook point, but don't know how or where to start from the rpython source code. I ran gdb against pypy binary and found it really hard to get to the entry … [View More]

PGO Optimized PyPy Built
by Singh, Yashwardhan Aug. 2, 2016

Aug. 2, 2016

Hi Everyone, I was wondering if someone has tried to build pypy using PGO ( Profile Guided Optimization) and LTO (Link Time Optimization). CPython has an option of building the binary using PGO and LTO, which gives performance speedup upto 26% on some of the GUPB benchmarks, with average gain of 10% over the whole benchmark suite. http://bugs.python.org/issue24915 Regards Yash
