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 17456 billion floating point operations per second (gigaflops), or 1450.1 CPU years (Pentium 90Mhz) computing time per day. For the testing of Mersenne numbers, this is equivalent to 623 Cray T916 supercomputers, or 311.5 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.)

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.

* Hourly World Test Status Summary

But when are we going to finally break that 18 Teraflop "barrier"?

lpmurray · 2005-03-15, 12:51

I predict that we will break and sustain 18 tflops within the next 30 days. We have picked up 7315 computers in the last 30 days. They are split fairly 50/50 pentium/athlon. If alot are working on 10million digit numbers, results should start coming in over the next 30 day period. Since its about a 10% increase in computers we should see about a 10% increase in tflops. Hence that 18 tflop barrier shall fall soon...

Actually if we don't loose computers we should be able to sustain 18.5 tflops in the next 30-45 days

How many floating point operations is LL test of M(p) as a function of p?

Are trial factoring and P-1 factoring counted in total floating point operations?

I guess a lot of people installed prime95 after the last prime discovery without really understanding what they were doing.

Discouraged by the long time it takes to do a single test, many uninstalled or forgot about the program.

I think you are right. That reminds us again that the server should assign DCs for every new user/machine, at least on his/her first assignment. This would serve the dual purpose of allowing the user to assess the reliability of the machine, and substantially reducing the time to obtain a first result. It would also help pushing forward the DC ranges, that are far behind the 1st timers.

kelman66 · 2005-06-19, 22:58

I think one thing that could contribute to the reduction in computers is the end of the college year in April/May.
I think there are a number of computers that go offline during the summer (at least) that way.
