    Re: 2,1037- sieve

    Here's the situation:

    As of 22:55 GMT there are 381 wu's left. I have 260 and Steve has 121. Cancelled rate of 20 %. Less than 12 hours to completely finish 2,1037- sieve.

    Good work Steve!

    Nice that you achieved your main goal Carlos and had a HAPPY CHRISTMAS. Good that STE\/E and the team could help you for the best and STE\/E is still helping.

    Nice to see a part of the work done. That is a battle we are all about to won. Congratulations to all that helped.

    Next goal while Greg runs post-processing of 2,1037- on the cluster is to sieve 2,1049+. This latter number is harder than the former. More 6 months sieving it....lol

    Here's a reply from Greg:

    For a number this large I do the collection and duplication removal in stages, so I don't have a total raw relation count at hand. I will report the size of the duplicate-free file and the number of unique relations when I have them. I'm processing the last half-million result files now.

    Re: 2,1037- sieve

    Damn memory, I don't remember where is the post that I promised a video about Rio de Janeiro. Well the video, is very simple but it is here Carlos.

    And Carlos the light of the city is amazing, no pictures make justice to beauty of Rio. Now I want to go there also...



    I will make a better video on a near future.

    Re: 2,1037- sieve

    Thank you Ricardo.

    Greg started the filtering on January the 4th. After dup removal, the file is

    -rw-rw-r-- 1 childers childers 90724638183 Jan 3 15:11 msieve.dat

    90.7 billion bytes is about 85 GB. Dup removal found

    Found 680357182 unique, 414377950 duplicate (37.9% of total), and 3722 bad relations.

    So the total file would have been about 135GB in size.

    I already asked Greg if LA is underway.

    The LA has started.

    matrix is 67008555 x 67008732 (29495.3 MB) with weight 8405533452 (125.44/col)

    linear algebra at 0.1%, ETA 447h56m

    LA is using 576 cores on Trestles at the San Diego Supercomputing Center.
