I stopped at 3.Never considered 7. I think I could try 6.
How do we find the latest apps?
How can I contact Gary?

I've downloaded CRUS_pack.zip, what do I do next?
The problem is that I can't register on mersenneforum.org:
I don't know the answer to this:
What year did Bernard Hinault win his first Vuelta a EspaƱa?
If I get past that, I post on which thread to tell the I reserved something?
And after I do, do I get any reply from them, like any files?
Then, how do we run those tasks?


1. you must ask google for the question
2. you must reserve a base in the reservation thread
3. the download package is very old, you need the latest apps
4. if you have a slow computer without AVX2 you can stop
5. with no knowledge about how to run you can stop
6. Maybe you can ask Gary how to run it
7. starting a new base with PFGW and multicore I can help (note there are no checkpoints and can take days from 1-2.5k), sieving included, then you must run millions of tests from 2.5-10k)

and after we posted?


If you want to use it private you must run the reserved range locally.

How can we reserve bases for the Mersenne CRUS project?


If you want to reserve any bases you must post it in their forum but keep in mind that could take months to finish it thats why we are splitting the work on SRBase using BOINC.

In the hall of fame it counts all the primes a user has discovered, or just the bigger primes?


not all only bases with <100 factors left

I will add more work tomorrow. Still running some missing stuff + double checks locally. Also planned the tiny R537. Sorry for any interrupts the last time. Not enough larger bases at the moment and a low turnaround time. All apps were sent out and still waiting for the results.

Hi, from what I've understood about the nature of the project, before loading new
work, the precedent batch needs to be completed. This naturally induces people to store a lot of WUs in their cache, which in turn causes a general slow down.
Has it ever been thought to limit the number of WUs a device can store? Or even completely eliminate the possibility to do it? This could significantly decrease the time needed to complete a batch, and everyone would be able to get work until the batch is *actually* finished.


Its limited to 50 per core depends on the runtime. Yes I agree that the turnaround time is a bit low at the moment.
