The pi(x) computation has been divided in several pieces, called chunks. Each chunk has a duration of approximately 8 hours (equivalent time on a Pentium II 350 Mhz). Several consecutive chunks define what we call a range, and can be computed together. Some ranges need a precomputation, lasting at most half an hour (part D). Several memory mode exists, so that even people with only 10 Mo of available memory can contribute to the project.

The pi(x) computation is divided in several parts, called A, B, C and D, which correspond to non negligeable parts of the computation (more information about how the computation of pi(x) is made will be soon available on this site). Each part is divided in several chunks. To avoid that people computes the same chunks, a reservation is made. You just have to choose your range so that it fits into the available range values.

Instructions to choose your range :

• Choose one range at a time
• Better choose consecutive chunks instead of choosing several ranges.
• If you have a lot of physical memory available (say more than 128 or 256 Mo), better choose your range in the C or D part, which requires more memory. The A and B parts better fit to machine with limited memory.
• To avoid abusive reservations and to optimize contributions, your reservation should correspond to a computation that you can complete in at most one week (your reservation will be cancelled after this delay).

Available ranges (the notation A-10-12 means Part A, chunks 10, 11 and 12 ) :

Free ranges for Part A : No range available

Free ranges for Part B : No range available

Free ranges for Part C : No range available

Free ranges for Part D : No range available

All chunk have been reserved. A future computation will be soon available.
