There we go Carlos. LaF is now history. About 2 months now and we'll catch up to Sic.

Thank you. I'll be joining you on Tuesday, post-processing integer 375086223641_19_minus1 is less than 48 hours to be completed.

I've thrown a few cores here myself till next months Simap.

Mumps is amazing.

Nice Mumps, without Free-DC I am lost on the team output. I should have noticed. Congratulations to all the team but most of all to you Mumps as Mike said you are amazing.

Anyway, about sieve, to maximize the output credit, and for the ones who have at least 1300 MB per core available, the 16e V5 siever must be chosen.

I'm back to sieve, let's try to reach Sic team shall we?
BTW, here's the log file of my post-processing run so that SETI.USA members can understand how long can take an integer to post-process. It was done on Win 7 core i5 750 @3.4 GHz 8 GB , I don't earn BOINC points.
375086223641_19_minus1.zip

The filtering phase is done under one core (RelProcTime: 5391 secs), linear algebra phase in all cores (4, BLanczosTime: 1105618 secs) and finally the square toot phase one core only (sqrtTime: 17118 secs).
If I had all cores running 16e V5 siever (BOINC) for the same amount of time as the post-processing, taking into consideration that no cores are idle as in filtering and square root phases, this run would get me something like 163.6k BOINC points.
So far I have made at NFS@Home an equivalent of 400k BOINC points with post-processing.

[pinhodecarlos]

I need to know when will SETI.USA make a full run on NFS@Home otherwise I will concentrate my effort on another math project where I can get some math granted.
Thank you in advance,

Carlos, I can't say when that would happen. This time of year in the U.S. has many members focused on the holidays. Yo may wish to relight the fire say around January?

I won't be here, I'll be moving to another country to live where I will have no internet access for awhile nor a computer to crunch.
