(I hope the above translates into "Excuse me please, I don't speak French") [English] I've been thinking about the ICFP'98 programming contest which will be judged on a "four-processor 150MHz Pentium-Pro box with 128 mbytes of memory running Linux SMP". I'm wondering if anyone can tell me: 1) Do I need to do anything in particular or organize my program in a certain way for me to take advantage of the multiple processors? Do I need to seperate my program into multiple threads or processes? Are there any special calls I must invoke or libraries I must utilize. 2) Beyond that, what do I need to do to take advantage of parallelism. Here is a quote from the web site : http://www.ai.mit.edu/extra/icfp-contest/ >On Thursday, August 27, 1998, a challenge task will be posted >on the Internet. Teams will have 72 hours to implement a >program to perform this task and submit this program to the >contest judges. The judges will perform a competition among >the submitted programs on a four-processor 150MHz Pentium-Pro > box with 128 mbytes of memory running Linux SMP. >Although the precise task chosen will not be revealed until >the contest begins, performance matters. Algorithm >cleverness matters. We have specifically chosen a parallel >machine for the contest so that programs may exploit >parallelism. Programming languages that help programmers >to rapidly construct complex systems may allow contestants >to attempt particularly sophisticated implementations in >the 72 hours allotted for programming.
