Cross-post from python-ideas: Compressing the stack on the fly
by Ram Rachum 28 Jul '14

28 Jul '14

Hi guys, I made a post on the Python-ideas mailing list that I was told might be relevant to Pypy. I've reproduced the original email below. Here is the thread on Python-ideas with all the discussion.<https://groups.google.com/forum/?fromgroups#!topic/python-ideas/hteGSNTyC_4> -------------- Hi everybody, Here's an idea I had a while ago. Now, I'm an ignoramus when it comes to how programming languages are implemented, so this idea will most likely be either (a) completely impossible or (b) trivial knowledge. I was thinking about the implementation of the factorial in Python. I was comparing in my mind 2 different solutions: The recursive one, and the one that uses a loop. Here are example implementations for them: def factorial_recursive(n): if n == 1: return 1 return n * factorial_recursive(n - 1) def factorial_loop(n): result = 1 for i in range(1, n + 1): result *= i return result I know that the recursive one is problematic, because it's putting a lot of items on the stack. In fact it's using the stack as if it was a loop variable. The stack wasn't meant to be used like that. Then the question came to me, why? Maybe the stack could be built to handle this kind of (ab)use? I read about tail-call optimization on Wikipedia. If I understand correctly, the gist of it is that the interpreter tries to recognize, on a frame-by-frame basis, which frames could be completely eliminated, and then it eliminates those. Then I read Guido's blog post explaining why he doesn't want it in Python. In that post he outlined 4 different reasons why TCO shouldn't be implemented in Python. But then I thought, maybe you could do something smarter than eliminating individual stack frames. Maybe we could create something that is to the current implementation of the stack what `xrange` is to the old-style `range`. A smart object that allows access to any of a long list of items in it, without actually having to store those items. This would solve the first argument that Guido raises in his post, which I found to be the most substantial one. What I'm saying is: Imagine the stack of the interpreter when it runs the factorial example above for n=1000. It has around 1000 items in it and it's just about to explode. But then, if you'd look at the contents of that stack, you'd see it's embarrassingly regular, a compression algorithm's wet dream. It's just the same code location over and over again, with a different value for `n`. So what I'm suggesting is an algorithm to compress that stack on the fly. An algorithm that would detect regularities in the stack and instead of saving each individual frame, save just the pattern. Then, there wouldn't be any problem with showing informative stack trace: Despite not storing every individual frame, each individual frame could still be accessed, similarly to how `xrange` allow access to each individual member without having to store each of them. Then, the stack could store a lot more items, and tasks that currently require recursion (like pickling using the standard library) will be able to handle much deeper recursions. What do you think?

Python vs pypy: interesting performance difference [dict.setdefault]
by David Naylor 10 Mar '14

10 Mar '14

Hi, I needed to create a cache of date and time objects and I wondered what was the best way to handle the cache. For comparison I put together the following test: <file="iforkey.py"> import datetime import random import timeit ranges = [datetime.datetime(2011,01, random.randint(1, 31)) for i in xrange(1000)] def ifdict(): cache = {} b = [] for i in ranges: key = i.day if key in cache: b.append(cache[key]) else: date = i.date() cache[key] = date b.append(date) def keydict(): cache = {} b = [] for i in ranges: key = i.day try: b.append(cache[key]) except KeyError: date = i.date() cache[key] = date b.append(date) def defaultdict(): cache = {} b= [] for i in ranges: b.append(cache.setdefault(i, i.date())) print "ifdict:", timeit.repeat("ifdict()", "from __main__ import ifdict", number=10000) print "keydict:", timeit.repeat("keydict()", "from __main__ import keydict", number=10000) print "defaultdict:", timeit.repeat("defaultdict()", "from __main__ import defaultdict", number=10000) </file> # python iforfile.py ifdict: [2.432887077331543, 2.4002890586853027, 2.397233009338379] keydict: [2.3483030796051025, 2.358638048171997, 2.314802885055542] defaultdict: [3.5384328365325928, 3.5329859256744385, 3.5728111267089844] # pypy iforfile.py (pypy 1.5) ifdict: [0.8129069805145264, 0.74648118019104, 0.7432689666748047] keydict: [0.5187451839447021, 0.4662129878997803, 0.4504108428955078] defaultdict: [37.98510789871216, 37.859113931655884, 37.92770600318909] Pypy displays significant slowdown in the defaultdict function, otherwise displays its usual speedup. To check what is the cause I replaced i.date() with i.day and found no major difference in times. It appears dict.setdefault (or it's interaction with jit) is causing a slow down. Regards

numpy fails trigonometry with complex numbers, what to do?
by Matti Picus 22 Dec '13

22 Dec '13

I am trying to complete complex numbers in numpypy. Progress is good, I picked up from previous work on the numpypy-complex2 branch. Complex numbers come with extensive tests, it seems all the corner cases are covered. In porting the tests to numpypy, I came across a problem: numpy returns different results than cmath. Some of the differences are due to the fact that numpy does not raise a ValueError for dividing by 0 or other silly input values, but other differences are inexplicable (note the sign of the imaginary part): >>> numpy.arccos(complex(0.,-0.)) (1.5707963267948966-0j) >>> cmath.acos(complex(0.,-0.)) (1.5707963267948966+0j) >>> or this one: >>> cmath.acos(complex(float('inf'),2.3)) -infj >>> numpy.arccos(complex(float('inf'),2.3)) (0.78539816339744828-inf*j) Should I ignore the inconsistencies, or fix the 700 out of 2300 test instance failures? What should pypy's numpypy do - be consistent with numpy or with cmath? cmath is easier and probably faster (no need to mangle results or input args), so I would prefer cmath to trying to understand the logic behind numpy.

PyPy doesn't make code written in C faster
by Armin Rigo 18 Jul '13

18 Jul '13

Hi all, Some people learn about PyPy, and the first program they try to measure speed with is something like this: def factorial(n): res = 1 for i in range(1, n + 1): res *= i return res print factorial(25000) It may not be completely obvious a priori, but this is as bogus as it gets. This is by now only 50% slower in PyPy than in CPython thanks to efforts from various people. The issue is of course that it's an algo which, in CPython or in PyPy, spends most of its time in C code computing with rather large "long" objects. (No, PyPy doesn't contain magic to speed up C code 10 times.) In fact, this program spends more than 2/3rd of its time in the final repr() of the result! Converting a long to base 10 is a quadratic operation. Does it still make sense to add programs like this to our benchmarks? So far, our benchmarks are "real-life" examples. The benchmarks like above are completely missing the point of PyPy, as they don't stress at all the Python interpreter part. There are also other cases where PyPy's performance is very bad, like cpyext on an extension module with lots of small C API calls. I believe that it would still make sense to list such cases in the official benchmark, and have the descriptions of the benchmarks explain what's wrong with them. A bientôt, Armin.

For what it's worth, the time for str(long) / time for recursive algorithm does decrease steadily for increasing input lengths. But it's not n^2 / n log n. Perhaps we need to implement a faster divmod? Can I assume that bit_length() is O(1)? I checked Knuth last night, he doesn't have anything to say in the main text, but he says in exercises: (II.4.4) 14. [M27] (A. Schonhage.) The text's method of converting multiple-precision integers requires an execution time of order n^2 to convert an n-place integer, when n is large. Show that it is possible to convert n-digit decimal integers into binary notation in O(M(n)logn) steps, where M(n) is an upper bound on the number of steps needed to multiply n-bit binary numbers that satisfies the “smoothness condition” M(2n) >= 2M(n). 15. [M47] Can the upper bound on the time to convert large integers, given in exercise 14, be substantially lowered? which fits my intuition. I'm fairly sure that my (and bokr's) algorithm is O(M(n)logn). It also suggests I'm wrong about a linear time algorithm (though the question doesn't state either way, but given it's M47 hardness, I'm probably not going to be able to whip this up tonight :) Lloyd Allison observed that changing any bit can affect any digits, which makes beating n log n less likely. One of the main reasons I use python is because it lets me concentrate on the higher level algorithms (like haskell), but it is pragmatic about the way we tend to write programs (unlike haskell :). I doubt I could have written that algorithm in C before breakfast (as I did for the python version). But to the main point: is it fair for people to compare code which doesn't get the benefit of pypy? Yes it is. Because the majority of code out there today is going to have C calls. Sure, pypy will lose on those, but that provides incentive to fix the problem - for example, implementing a better long to string. People are going to write silly benchmarks and they are going to solve problems in silly ways. We should be honest about this in the benchmarks. Don't worry, pypy will do just fine.

RPython
by Dirk Hünniger 28 May '13

Hello, I am working on a compiler for MediaWiki to LaTeX. Currently it is written in Haskell and Python3. I feel very insecure about the Python part and I would feel much safer if I had static typechecking in the Python part. Still I want the Python part to be able to run with normal Python interpreter. So it seems to me that converting the code to RPython might solve this issue for. Everything else is Ok, in particular speed is not an issue. What do you think. Yours Dirk PS: link to my repository http://sourceforge.net/p/wb2pdf/code/HEAD/tree/trunk/src/

Cross-post from python-ideas: Compressing the stack on the fly
by Bart Wiegmans 28 May '13

28 May '13

Hi Ram, That is a daring idea, really. But since you asked it, I will tell you what I think. I think it is a bad idea. First of all, the complexity of implementation. I see two 'obvious' implementations of your idea, which is a): an 'on-line' stack compressor, which will slow down functions calls farther than they are already (in CPython, anyway), or b): a 'just-in-time' stack compressor that is initiated when the 1000th stack frame is reached. I can imagine this happening in-place, but it won't be efficient. Now consider what happens when an exception is raised from the bottom to the top.Or worse, from the bottom to somewhere-in-the-middle. The second point concerns the possible gains. Suppose your recursive factorial stack is compressed. At the very least, any compression algorithm must store the decreasing integer that is multiplied. (You might get away with detecting the pattern, but don't count on it). At best, you might run your recursive algorithm a bit longer, but it will overflow eventually. In other words, on a machine with a finite stack size, the algorithm is *wrong*. The correct recursive implementation looks like this: def factorial(x): def recursive(x, c): if x <= 1: return c return recursive(x-1, x * c) return recursive(x, 1) Which doesn't need to store the decreasing x on any stack, and is thus a prime candidate for TCO. The third point concerns the reason why python does not have TCO in the first place. I've read Guido's blog as well, and in my opinion, he's wrong to make such a distinction between what are essentially nearly identical processes: jumping to new code locations. As it is, however, he's dictator. In python, you're simply not /supposed/ to use deep recursive algorithms. It is considered un-pythonic. Nevertheless, I like the style of your idea :-).
