Oops - New Prime! (M49 related)
A new prime has been reported to the server. We need a CUDALucas volunteer to verify -- contact madpoo.

Aaron, James and I have egg on our face. The prime was reported last year but went unnoticed (again) for months. I have a plan to make sure this does not happen again (failure of the automated announcement email)

I'll be back from a brief trip in 36 hours with more details.

Anyway, great news!! Congrats to GIMPS! (pending official verifications)

Is it bigger than $2^{57885161}-1$?

ATH 2016-01-09 19:16

That is great news, even though the method of discovery is not optimal :smile: Let's cross our fingers that verification holds.

I can start verification on my 5960X (ETA 44-48 hours if the expoment is in the 61-64M range), and I can check on my Titan Black with CudaLucas.

Yeah, seems like I´ve been too much distracted... :whistle:

Anyway, great news, as you said. We´re en route to another great moment of excitment.
GIMPS is alive and kicking!

Wow! Take all the Time you need!

M49* found for real? Happy New Year again!

Fingers crossed.....

Is there any error code? What are your thoughts as to the odds this is a legitimate find?

(...Would anyone be willing to PM me the exponent in question? lol. I can offer only an i7-2600K, with either Prime95 or Mlucas.)

ramshanker 2016-01-09 19:57

I can feel the rush in my vain...:grin:

Madpoo 2016-01-09 20:09

Here's what can be said:[LIST][*]no error codes in the run[*]the exponent is between 2 and 595e6 :smile: (couldn't resist, sorry, but not sorry)[/LIST]
I would love to get someone with CudaLucas and the fastest dang GPU out there so we can do the code/platform independent run ASAP

What's the fastest GPU for LL testing? Anyone with a Tesla K80 or a Titan X / Z ?

The current best offer on the table is a Titan Black from ATH.

Have both X and Zs handy, I can run it on both if you like

ATH 2016-01-09 20:15

My 8 cores CPU is a bit faster than my Titan Black, but that way I can get a preliminary verification on the CPU and then another one a few hours later on the GPU.

Titan X has lousy double precision performance?

I think we have a winner here. I was hoping AirSquirrels was awake and looking at the forum on a weekend since I knew he had some GPUs available.

Send me a private message with your email address and I'll send the details.
