GCW - Snark Hunt - 21-28 November

Announced is a seven day challenge at the GCW (Generalized Cullen/Woodall Prime Search) from the 21st until the 28th of November. I suggest we start at 12:00 UTC and end at 12:00 UTC.

Lewis Carroll was an English writer, mathematician, logician, Anglican deacon, and photographer. His most famous writings are Alice's Adventures in Wonderland, its sequel Through the Looking-Glass, which includes the poem Jabberwocky, and the poem The Hunting of the Snark. He is noted for his facility at word play, logic, and fantasy. There are societies in many parts of the world dedicated to the enjoyment and promotion of his works and the investigation of his life.
The Hunting of the Snark follows a crew of ten trying to hunt the Snark, an animal which may turn out to be a highly dangerous Boojum. The only one of the crew to find the Snark quickly vanishes, leading the narrator to explain that it was a Boojum after all.

The objective of the GCW prime search will be to discover primes on bases that have yet to yield a prime. So, like a Snark Hunt it is not for the faint hearted! Generalized Cullen/Woodall Prime Search was originally only for base 13. Now it has extended to several bases. Its currently searching for Generalised Cullen primes n*b^n + 1 for bases 41, 47, 49 and 53. If a prime is found, searching on that base will stop, proving it was a Boojum after all.

More about the GCW prime search can be found here. News and infos about the PRPNet client can be found here.

To take part, you have to activate the following lines in prpclient.ini:

server=GCW:100:1:prpnet.primegrid.com:12004

Stats will be available at the well known place here.

All previous PRPNet challenge stats can be found here.

Good luck!

Bases will be run in the order they were loaded. Right now the port is sending out base 47, then 49, 53, 41 and finally 29 which just got loaded, 500K<n<1M. Base 55 is next to be loaded and will start after 29 is completed. Any prime found on 41, 47, 49, 53 is a megaprime (well over a million digits) and would make the top 100 primes.

This port used to send out work in ascending order by size, but if left that way the only way to actually finish a base would be to let the port completely run dry. This way we can finish off a base and if needed start sieving it for the next n range.

Leading edge has finished the Base 47 range < 1M, now onto Base 49.

After crossing the sea guided by the Bellman's map of the Ocean—a blank sheet of paper—the hunting party arrive in a strange land, and the Bellman informs them of the five signs of a Snark: its "meagre and hollow, but crisp" taste; a habit of rising late and taking breakfast during five o'clock tea; "its slowness in taking a jest"; a "fondness for bathing-machines"; and its ambition. The Bellman warns them that some Snarks are highly dangerous Boojums, causing the Baker to faint. Once revived, the Baker recalls that his uncle warned him that if the Snark turns out to be a Boojum, the hunter will "softly and suddenly vanish away, and never be met with again." The Baker confesses that the notion of this sudden vanishment brings him much distress.

Message 89991 - Posted: 25 Nov 2015 | 7:06:50 UTC

We're completing about 420 WU's per day, which will work out to 3000 WUs over the Challenge.

Base 47 only 15 WU's left, so we've most definitely captured this Snark.
Base 49, about a days worth left before we capture this one, unless it turns out to be a Boojum of course.
Then we'll finish off the Challenge chasing Base 53.

With this in mind, they split up to hunt the Snark: "They sought it with thimbles, they sought it with care; / They pursued it with forks and hope; / They threatened its life with a railway-share; / They charmed it with smiles and soap." Along the way, the Butcher and Beaver, previously mutually wary, become fast friends, after the Butcher teaches it more in ten minutes than it could learn from books in seventy years. The Barrister, meanwhile, dreams of the court trial of a pig accused of deserting its sty, whom the Snark is defending. The Snark, however, finds the pig guilty and sentences it to transportation and a fine of forty pound. His dream concludes with the jailer informing the court that the pig has actually been dead for years, to the judge's disgust.

We've captured another Snark!
Leading edge has finished the Base 49 range < 1M, finally onto Base 53.

During the hunt, the Banker finds himself attacked by a bandersnatch, and loses his sanity after trying to bribe the creature. At the conclusion of the poem, the Baker calls out that he has found a snark, but when the others arrive, he has mysteriously disappeared, leading the narrator to explain: "For the Snark was a Boojum, you see."
