Sieving for CRUS

[MisterBitcoin]

Without reserving it I sieved R548 more deeper to p=20T.

Next one (R523) will be done in 2 days, depth 20T.

R958 has been sieved to P=30e12 for n=200k to 500k and should be ready for immediate PRP testing. It took ~8500 seconds to PRP test n=400,000, and I sieved until the seconds per factor roughly matched that.

File is attached.

R523 is finished to p=20T.

Next one (R549) will be completed in 2 days.

I'll sieve S758 from n=200k-500k.

Well. You made my day.
(I´m new, too.)

You wanted to reserve work for a few months. :)

If you´re not trolling, take a look to this thread: http://mersenneforum.org/showthread.php?t=9742

Or just wait a few minutes and read the following replys.

Thank you, MisterBitcoin.

I am interested that why nobody reserved S30 to n=1M? It and S117 are the only two base b<=200 with <=5 k's remaining and not sieved to n=1M.

Before starting any work, talk with @gd_barnes about that. There are lot lot of mistakes you can make if your not 100% sure what your doing.
Reserving 1-2 bases for sieving is okay, but not that much like your trying.
Informations can be found on this thread. too.

Since the project is so huge, frequently holes are left in efforts and are missed for several years. I somewhat attempt to mitigate that with the recommended bases thread but I don't specifically look at "sieving holes" just testing holes. Part of the problem here is that more people are interested in sieving/testing Riesel bases than Sierp bases. Feel free to begin on S30. As a starting point, I suggest sieving to at least P=25T. It will likely need to ultimately be sieved further but 25T is a good starting point. It will take a while so you might run a small test sieve first to see how long you think it will take you. After looking into it, let me know if you would like to officially reserve it.

By the way, sieving depht for S17. I suggest p=90T or just the time to eliminate 1 canidate. (60% Rule.) ?
N-Value is going up to 5M.
