i´ve to wait for a userfriendly reservation interface.

Norman, you can choose any kind of reservation, as long as it does not overlap or leave holes in the completed ranges.

Example: F31 is done up to k=5*10¹⁴, you can ask for k from 5*10¹⁴ (that is between 2⁸¹ and 2⁸²) to 2⁸³ or 1125899906842624.

Or k from 5*10¹⁴ to 10¹⁵.

The range will take approx. 75 minutes on a GTX 460.

OK, that is a known "feature" of mmff.
When the range crosses a bitlevel, we have 2 rows for one k_range...

Did you get my answer for the ranges?

Luigi

P.S. That's quite FAST!

It is warp speed fast! It was a test, now the 150T-275T range is in progres;. ETA 17hrs.
F44 also progressed well overnight.
When a hundred people will start cranking, we could see a dozen new Fermat factors by the end of the month, I guess...

Please, if you want a new range email me both the request and the results.txt file at the end, so that I can keep a record of who did what...

Not so fast, please... I can't buy a new GTX580 before December!

There are lots of ranges in the Double Mersennes...

Yes, the database s ready, I'm filling in the results.

I'd like to run a test, can you give me a range to run? Thanks.

[firejuggler]

ET_, I didn't mean to 'overhelm' you with result. Just wanted to show people the 'speed' of Prime95's tool.

As I get a 'bus' tour of Mexico From the city to Cancun, and visitin Mayan ruins, I can't get a reservation yet. I'm Going there to check the Mayan calendar..

Be sure to arrive before Dec. 20th...

I reserved the F31 range to you, anyway. Let me know when and how you finish, good luck!

Today I received more reservations than the last 15 days, I'm trying to keep up with the work while updating the site.

Sure! On Double Mersennes or on FermatSearch? If on FermatSearch, let me know how long you want to run the program, and PM me your name/surname/avatar_name/whatever_you_want_to be_shown_on_the_site and your home country.
