Sierp base 3  minidrive Ia
We have started a mini drive for Sierp base 3. The range is k<50M and n=35K100K.
There were 154 k's remaining to begin with. The drive found 81 k's with primes so there are now 73 k's remaining for this krange. This is a very lowintensity drive. The files are small and you should be able to complete files at the current nrange in 47 days. Feel free to grab several if you like. As we find primes, like I did with primes that were previously found, we'll remove k's from files for larger nranges. Files up to n=100K are fully sieved to P=175G.

reserving : 35K36K

reserving : 36K37K

Two primes found:
12562406 35092 38353046 35109 Do I have to remove these k's (12562406 & 38353046 )from imy nput file? 
Taking 37K38K. Removing the two k's that Cedric found primes for.
This is mainly to balance the amount of work on my NPLB 530.0530.6 range between my cores. For some reason, 530.3530.6 has way more pairs to test that 530.0530.3 did, and I'd like to find a few small primes anyway. :smile: Edit: If I find a PRP with this, should I just report it here as a PRP or check it first? Either way, how do I check it for 100% certain primality instead of just PRP?

Just a little warning, though: after you've removed the k's from the input file, make sure you adjust the current line being processed as stored in llr.iniotherwise, you'll end up skipping a whole chunk of the file. 
[quote=henryzz;138452]u can use pfgw to prove them prime
the options t tp and tc all prove primality[/quote] You would use the t option for +1 tests. tp is for 1 tests. tc tests both but is generally used for random forms (i.e. k*b^n+7) and would take an unnecessary amount of time for +1 or 1 tests. Gary

Removing 2 out of 154 k's will only save you about 2 / 154 = 1.3% CPU time. I'll get them removed from the n>38K files later today. Gary 
30494864*3^37165+1 is prime! (from PFGW, so this is verified)
Removing from my file... I used t. It only took 10 seconds longer than it took to PRP it (~41 vs ~31). Edit: Is there any existing tool to more easily remove a k from an LLRformatted file? I'm not worried about the line number, as I could manually clear out the ones I've finished and restart it on line 1, but the new line number you need to run on would be nice too.

Never mind, I noticed that srfile can do this and found the command. (I can't still edit the above post.)
