| Collaborative Computing Projects | ||||||||
|
If you have got free computer time or if you think your computer is fast enough than join these collaborative computing projects and make your system useful and you could win prizes also. "A busy computer is a Happy Computer." I have done some analysis and found out the following specs for the type of processor you have.
You can run multiple projects at the same time on your system, because only your idle processor time is utilized so your normal work does not suffer. And don't forget to join the SoftWhere Teams on these projects. |
| SETI@Home 1.06 | ||||||||||

Do you think we are alone in the universe ? SETI@home is a scientific experiment that harnesses the power of hundreds of thousands of Internet - connected computers in the Search for Extraterrestrial Intelligence (SETI). You can participate by running a program that downloads and analyzes radio telescope data. Once every few days, you download a packet of information from the internet containing data from a large satellite. Your computer spends the next few days interpreting the results, either as a screensaver or an always - running program. Once you are finished, it will submit it's results and download a new packet. There's a small but captivating possibility that your computer will detect the faint murmur of a civilization beyond Earth. Well whatever you think here is your chance to prove it. If you believe that we are alone, participate so that this project may fail. And if you think we are not alone participate, because this project may succeed.

| Distributed.net | ||||||||||
|
As a "loosely knit" group of computer users from all over the world, they take up challenges which require a lot of computing power. They solve these by distributing the cpu power needed over the computers of their members. That's why called "distributed.net" This client is capable of working on two of distributed.net's ongoing projects: The brute-force decryption of a RC5-64 message, and the brute force decryption of a DES message. The RC5-64 contest is a long-term contest, which may take a couple of years to solve. The DES contests, run twice a year, are short, and should take less than a month to solve. As a result, this client will work on DES during DES contests, and switch back to RC5-64 when no DES contest is going on. No user intervention is required for this switchover. (You could win up to US$ 1,000 if you join this project. Read the documentation and visit web site.)

| PrimeNet | ||||||||||

With this software you could discover one of the most coveted finds in all of Mathematics - a new Mersenne prime number. What are Mersenne Prime Numbers ? Mersenne numbers are named after the French monk Marin Mersenne, who stares at you from the background. These numbers are of the form 2P-1. A small percentage of these numbers are prime. The Electronic Frontier Foundation is offering a $100,000 prize to the first person to discover a ten million digit prime number. And this project is sure to find one because they have discovered four Mersenne primes so far. On June 1st 1999, Nayan Hajratwala found the current world record prime, 26972593-1. On January 27th 1998, Roland Clarkson found the current world record prime, 23021377-1. On August 24th 1997, Gordon Spence found the previous world record, 22976221-1. In November 1996, Joel Armengaud found the prime 21398269-1. Could you be next?

| PiHex 6.0 | ||||||||||

PiHex is both the overall project and the program you download, which is, strictly speaking, the PiHex client. PiHex (the project) is a distributed computing project using idle time slices on computers scattered around the world to calculate specific bits of Pi without computing all the previous bits. In this way, PiHex is ideally suited to highly parallel systems (such as the internet) where each computer only has a very limited amount of memory -- with about 100K of memory, PiHex can compute the five trillionth bit of Pi, whereas 'classical' algorithms for computing Pi, which compute all the bits up to a certain point would need over a terabyte of memory, which is out of reach for all but the world's most powerful supercomputers. PiHex uses Bellard's formula, essentially a refinement of the BBP formula which expresses Pi as an infinite sum. To calculate the five trillionth bit, we need to add up the five trillionth bits of seven trillion terms. I assign ranges of terms (eg, first two hundred billion terms) for each computer to add up, and then author add all the results together at the end. Since PiHex only uses idle time slices, it should not interfere with any other programs you are running. Thus, you can leave it running all the time. PiHex subdivides the assigned range into smaller sub-ranges, and writes the sum of each subrange to the output file when it completes, so if your computer crashes at some point, PiHex might lose half an hour of work, but it should be able to restart without any problems. PiHex is designed to use all the available CPUs: It spawns a separate thread for each CPU to do that CPU's calculations. Therefore, if you have a multi-processor machine, you only need to have one copy of PiHex running. For this reason, PiHex will not allow you to have two copies running at once.
