ware in Python. The serial Python version performs com-parably to the baseline Perl. With the described algorithm the total execution time for the most costly particle was still brought down to 78.8 seconds, or about a 6.5x speedup over the original Perl code. This brings the computation down into the realm of acceptability.

This results in a loop that never ends. Such a loop is called an infinite loop. An infinite loop might be useful in client/server programming where the server needs to run continuously so that client programs can communicate with it as and when required. #!/usr/bin/python var = 1 while var == 1 : # This constructs an infinite loop
