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 31313 billion floating point operations per second (gigaflops), or 2601.2 CPU years (Pentium 90Mhz) computing time per day. For the testing of Mersenne numbers, this is equivalent to 1118 Cray T916 supercomputers, or 559 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, the PrimeNet Statistics or the PrimeNet Project Credits.

Current Internet PrimeNet 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.
