Linux Cog VM crash
by Guillermo Polito 10 Feb '11

10 Feb '11

Hi! Yesterday I downloaded the Linux Cog Vm in http://www.mirandabanda.org/files/Cog/VM/VM.r2361. So far so good until this morning. When I wanted to commit to monticello, the vm and image get closed with no log and no error :(. Any help will be appreciated, Thanks! Guille

Clarification of license statement for SqueakSource VMMaker repository
by David T. Lewis 09 Feb '11

09 Feb '11

Folks, The project overview text for the VMMaker project on SqueakSource was written a number of years ago prior to the full Squeak relicensing and is now misleading with respect to license, which I believe to be fully MIT for all code in the VMMaker repository itself. For this reason, I would like to change the overview to include clarification of license status as follows: "This package incorporates the Smalltalk source code (Slang) for the virtual machine, as well as the code generator and toolset for creating the Squeak VM portions not handwritten in C (or whatever). The platform support code is maintained in a separate repository (currently Subversion at www.squeakvm.org). You will need to use a SVN tool to acquire the platform support code. See the Wiki page (tab above) for more info. License for VMMaker project is MIT. All code contained in this package is authored by signers of the Squeak license agreement and/or by persons contributing directly to this repository under MIT license terms. All new contributions to this project are required to be MIT licensed." Are there any objections or issues with making this change? If no objections I will do the update approximately two weeks from today. Thanks, Dave

Squeak vs Python "smack down"
by Göran Krampe 09 Feb '11

09 Feb '11

Hi folks! Since we are on the verge of 4.2, and we have a brand new Cog VM to play with I felt like dusting off my old Pystone port to Squeak - Sqystone, which I wrote back in 2004. At that time Squeak was around 5 times faster than CPython. How do we stack up today? Yeah, I know - hardly a good benchmark, they all lie etc etc. :) I am using Ubuntu 10.10 on a corei7, so this is running on a 64 bit CPU. Cog! ==== Squeak 4.2-10966 (soon to be released) + latest Cog r2361 (binary download): Pystone(1.1) time for 50000 passes = 0.06 This machine benchmarks at 833333.3 pystones/second NOTE: AFAICT running with more passes does not improve it. Also, not sure if I could get more out of this if I built from source on my box. Regular Squeak ============== Squeak 4.2-10966 (soon to be released) + regular Squeak VM 4.4.7-2357 (built from src): Pystone(1.1) time for 50000 passes = 0.503 This machine benchmarks at 99403.6 pystones/second Regular CPython =============== CPython 3.1.2 (newest in Ubuntu Meerkat, minimal): gokr@quigon:/usr/lib/python3.1/test$ python3.1 pystone.py Pystone(1.1) time for 50000 passes = 0.57 This machine benchmarks at 87719.3 pystones/second NOTE: 3.2 is reportedly a teeny bit faster. Also not built from source. Pypy 1.4 ======== wget http://pypy.org/download/pypy-1.4.1-linux64.tar.bz2 gokr@quigon:~/python/pypy-1.4.1-linux64$ ./bin/pypy ./lib-python/2.5.2/test/pystone.py Pystone(1.1) time for 50000 passes = 0.15 This machine benchmarks at 333333 pystones/second gokr@quigon:~/python/pypy-1.4.1-linux64$ ./bin/pypy ./lib-python/2.5.2/test/pystone.py 5000000 Pystone(1.1) time for 5000000 passes = 4.8 This machine benchmarks at 1.04167e+06 pystones/second NOTE: Also not built from source. Here we run pystone a second time with 100x more loops and get a substantially better number. Shedskin 0.7 ============ sudo apt-get install g++ libpcre3-dev libgc-dev python-dev sudo dpkg -i shedskin_0.7_all.deb wget http://shedskin.googlecode.com/files/shedskin-examples-0.7.tgz shedskin pystone.py gokr@quigon:~/python/shedskin-examples-0.7$ make g++ -O2 -march=native -fomit-frame-pointer -Wno-deprecated -I. -I/usr/share/shedskin/lib /usr/share/shedskin/lib/builtin.cpp pystone.cpp /usr/share/shedskin/lib/time.cpp /usr/share/shedskin/lib/re.cpp -lgc -lpcre -o pystone gokr@quigon:~/python/gokr@quigon:~/python/shedskin-examples-0.7$ ls -la pystone* -rwxr-xr-x 1 gokr gokr 297329 2011-02-07 23:01 pystone -rw-r--r-- 1 gokr gokr 9193 2011-02-07 23:00 pystone.cpp -rw-r--r-- 1 gokr gokr 1893 2011-02-07 23:00 pystone.hpp -rw-r--r-- 1 gokr gokr 5774 2010-12-11 11:40 pystone.py gokr@quigon:~/python/shedskin-examples-0.7$ ./pystone This machine benchmarks at 2500000.000000 pystones/second NOTE: I am wondering a bit about this. It tells the same whatever loops I give it... But ok, perhaps it is all fine. Summary ======= - The regular Squeak VM has not been overrun by CPython in these 6 years time. When I wrote Sqystone Squeak was 5x faster IIRC (can't find the post anymore). Now they are equal more or less, Squeak still a teeny bit faster. - Cog is brutally fast on this one. Compared to CPython and regular Squeak almost 10x faster. - Pypy is about 20% faster than Cog if given enough time to actually start jitting. Cool for the Pypy project! And cool that they aren't that much faster than Cog. :) - Shedskin is the "state of the art" of statically compiling Python via C++ using type inferencing etc etc - so I hear. It is said to be faster than Cython and Psyco. It ends up beating Cog, but "only" by a factor of 3x. I say "only" because that seems pretty good to me given that Cog is a JIT and still pretty young and that Shedskin can only run a subset of Python. regards, Göran

Hi, does anybody has the alien plugin compiled for linux (plain squeak or exuperi or cog, is the same)? Cheers, Esteban
