    Re: Teams stomped by SETI.USA on NFS@Home

    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.

    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.
