On 2 Feb 2012, 21:30:55 UTC, PrimeGrid’s The Riesel Problem project eliminated k=162941 by finding the prime: 162941*2^993718-1 The prime is 299,145 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 1536th overall. This prime was found while exploring a suspected gap in a previously searched range. This is PrimeGrid's 8th elimination. 56 k's now remain. The discovery was made by Dmitry Domanov (unconnected) of Russia using an Intel Xeon @ 3.60GHz with 2 GB RAM running Windows Server 2003 Enterprise x86. This computer took just over 1 hour 5 minutes to complete the primality test using LLR. Dmitry is a member of Team Russia. For more details, please see the official announcement.

It turns out that some of the WUs cannot download the input files (they were missing); these files have been created now.

Due to a disk failure on one of the servers, the database and the replicated copy of it got corrupted. A restore was done from a known working backup of yesterday. Some WUs which were send out in the mean time might have been lost due to this. Currently the project runs on just one of the servers, later this week the second server will be put to action again. Sorry about that!

With the new server software release installed in the end of January we experienced that many more workunits are sent to the hosts as usual. We are currently investigating this, seems that the project contiguration settings are differently interpreted by the new software. To avoid total overload of hosts by SIMAP results, we have reduced the daily maximum number of results per host to 300. We will check and adapt this limit during the next days continuously.

Come join us in laid-back competition in tribute to the number 2...the first prime and the only even prime. The prizes are simple colored jerseys .
