I've processed much bigger files in Python without issues. –robert Nov 26 '10 at 12:14 1 What is your script trying to do? It looks to me like you want to calculate the average value of every fourth column in each of the input files. Is that right? –Tim Pietzcker Nov 26 '10 at 12:51 I have noticed significant performance differences in regard to Memory when running the same Python application on Windows (XP) and OS X/Linux. The performance on the Windows side tends to be the worst. –SW_user2953243 Jan 18 '15 at 1:41 add a comment| 5 Answers 5 active oldest votes up vote 15 down vote accepted This is my third answer because

You'd hit the same limits with 1gb of physical RAM, as long as you had a large enough swap file. There are two limits on an individual application, the amount of swap space, and the amount of address space. Swap space management depends on which "windows 32 OS" you're running, and how you have it configured. I will have to assume you mean one of Windows XP, Windows Vista, or Windows 7. And that swap space is shared among all the applications currently

When I give a large number(600851475143) as input, python memory error MemoryError pops up. Below is the code: def fact(a): factors = [] for i in range(1,a+1): if a%i == 0: factors.append(i) return factors num = raw_input(">> ") #600851475143 a = b = [] a = fact(long(num)) for i in range(0,len(a)): b = fact(a[i]) if len(b) <= 2: print a[i] From browsing I came to know that Python makes use of Computer memory - RAM. I am using Python in Unbuntu without changing its configuration. Should I change anythig to work on 64-bit machine. Or should I use any additional function(s) to get around this error python memory error-messages share|improve this question asked Jan 13 '15 at 18:47 Gdek 313 4 Your basic issue is that your algorithm is likely using too much memory. If you are using python 2, then range(1, a+1) is attempting to create a list with 600851475143 elements. This is probably not what you want as each element will be an integer and each integer takes 4 bytes. (Also, this question isn't appropriate for Programmers as you really need a code review and to understand in particular how python works.) –Steven

You can use this to customize the options that are passed to the JVM. The maximum heap size should be given by -Xmx750m There is a list of memory options in this blog post share|improve this answer answered May 25 '15 at 11:19 pyrocrasty 984614 add a comment| up vote 0 down vote Rather than manually searching for the right files, you can (at least in PyCharm 5) now just search for or navigate to "Edit Custom VM Options" and it will create and open a default vmoptions file for you, as described in https://www.jetbrains.com/pycharm/help/tuning-pycharm.html. Then, To increase PyCharm heap size, ... modify the -Xmx setting. EDIT: I don't know why, but this process created a pycharm64.vmoptions file for me and that didn't actually change the heap size (as indicated in the bottom right "Show memory indicator"). I actually had to rename that file to pycharm.vmoptions for it to work. share|improve this answer edited Jan 20 at 20:55 answered Jan 20 at 18:2
