Seit März 2019 rechnet ein Intel-NUC mit Intel(R) Core(TM) i7-8559U CPU an den Primzahlen, allerdings gedrosselt, da sonst der Stromverbrauch zu hoch ist. Dadurch erreiche ich nochmal knapp 50% weniger Stromverbrauch bei in etwa gleicher Rechenleistung gegenüber dem vorhergehenden PC. Folgende ältere Rechner haben bisher beigetragen:
Insgesamt rechne ich beim GIMPS-Projekt seit Juni 1999 mit. Schliesslich
bot die EFF (Electronic Frontier Foundation) ein Preisgeld von 100 000 US$ für denjenigen,
der die erste Primzahl mit mehr als 10 Mio. Stellen berechnet.
Der Preis wurde an das Mathematics Department der University of California, Los Angeles (UCLA) vergeben.
Dort wurde in 2008 mit Hilfe der GIMPS-Software eine Primzahl mit mehr als 12 Millionen Stellen gefunden (siehe auch
http://www.eff.org/press/archives/2009/10/14-0). Es sind neue Preise ausgeschrieben worden:
$150,000 to the first individual or group who discovers a prime with at least 100 million digits, and $250,000 for a prime with at least a billion digits.
Aktuelle Computer haben die Rechenleistung, um z.B. die P-1 Berechnung an 11-Mio-Exponenten in zwei bis drei Wochen durchzuführen, der CERT- Check dauert nur wenige Stunden.
Für viele Jahre wurden im GIMPS-Projekt Lucas-Lehmer-Tests ausgefürt, wobei zunächst geprüft wurde, ob es Faktoren
gibt, die kleiner als 2^68 sind. Manchmal wurden welche gefunden, diese sind in der nachfolgenden Liste mit dabei. Ebenfalls angegeben sind Exponenten, die doppelt überprüft worden sind (double-check). Diese wurden früher auf einem anderen Rechner ein zweites Mal per Lucas-Lehmer-Test gerechnet, um sicher zu sein, dass kein Berechnungsfehler vorliegt.
Neuerdings hat sich aufgrund eines mathematischen Durchbruchs die Methodik geändert. Im ersten Schritt (P-1) wird ein Test ausgeführt, bei dem ein Prüf-File mitgeschrieben wird (PRP proof). Im zweiten Schritt wird anhand von Zertifikaten überprüft, ob die Berechnung in P-1 einwandfrei war mit einem Bruchteil der Rechenzeit (completed CERT check).
Die folgenden 475 Exponenten haben meine Rechner bisher getestet (das M steht für Mersenne-Exponent):
