Hi,
I am trying to sort 500.000.000 numbers which are stored in a file. The file is approximately 5 GB in size. Initially, I read the numbers into an array and then perform merge sort. However, the memory is not enough to do the calculations and comparisons and after some time the program gives "Out of memory" error and dies.
Could you help me about this problem? Thank you.
Specifications:
OS: Debian 6
RAM: 2 GB
Swap: 2.6 GB

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
