Great Internet Mersenne Prime Search
PrimeNet is a
world-wide, distributed Internet research computing system
created in 1997 for the Great Internet Mersenne
Prime Search (GIMPS). For further information, please email primenet@mersenne.org.
The virtual machine's sustained throughput*
is currently 31061 billion floating point operations per second
(gigaflops), or 2580.3 CPU years (Pentium 90Mhz) computing time per
day. For the testing of Mersenne numbers, this is equivalent to 1109
Cray T916 supercomputers, or 554.5 of Cray's most powerful T932 supercomputers,
at peak power. As such, PrimeNet ranks among the most powerful computers in the world.
(*Measured in calibrated P5 90Mhz, 32.98 MFLOP units: 25658999 FPO / 0.778s using 256k
FFT.)
For more information, please see the GIMPS
home page,

Server World Test Status
All Times are in Coordinated Universal Time (UTC)
These reports indicate the virtual supercomputer's
operating status, automatically updated by the server every hour, on the hour. A
complete table of the GIMPS overall project
status is also available.
They consist of three sections: (1) system performance
information and active exponent test ranges, (2) current assignments issued to GIMPS test
clients, (3) exponents that have been eliminated as Mersenne prime candidates since the
last master database synchronization. Section (1) does not include exponents in progress
received from clients outside active IPS test ranges.
- Hourly World Test Status Summary
All Times are in Coordinated Universal Time
(UTC)
This summary
includes only section (1), and counts for sections (2) and (3).

This full length report includes section (1)
and the entire section (2) list of Mersenne test exponents in progress for all accounts.
When an exponent's Mersenne number is found composite, the exponent moves from this report
to the Cleared Exponents Report.

This full length report includes section
(3), exponents eliminated as Mersenne prime candidates since the last master database
synchronization. It very nicely reflects the expected operating trend that many more
factors should be found for exponents well ahead of the Lucas-Lehmer tests, which can be
seen as the diagonal distribution pattern from lower left to upper right in the Test
Distribution Map.
