We need your help on the challenge.
BTW, a new Win64 build was achieved faster as the linux one so it is a matter of time and test until NFS@Home publishes it to the clients.

Can I request CNT Team help on NFS@Home on lasieve5f application (now available also for Windows 64 bit)? Each thread will consume up to 1GB but right now it is consuming 430MB/thread.

2,1285- sieve has started. We will go up to q=2200M or 2400M, meaning we will have 1.09M wus to 1.19M wus to process.

For 6,490+ we stopped at q=1800M and now with less than 10000 outstanding wus.

Best Regards,

Sorry for the late reply. Some comments from Greg the Admin.

1) Server issues: "I think I tracked down the database slowdown. Turns out that the size of the database, specifically the host table, has grown substantially thanks to Syracuse’s 1.8 million host entries. It became larger than the cache assigned to it, so records were being read from disk rather than memory. That’s bad. I increased the max cache size to much larger than the table, so things should be back to normal now."

2) Records: "As far as setting a new record, the current lasieve16e binaries aren’t up to the task. They came close to running out of steam on our current records."
Also " I need to take a look at the full data set I have now and set priorities for the next grant proposal"

So we are trying to check from the Cunningham Tables and on other projects where we can be of assistant inside the limits of the sievers, closer to record pinch.

Thank you all for your support.
I'll let you know what will be the next integer to sieve.

Keep crunching, we are still far away to finish 2,1285-, more or less 850k wus.

Carlos

Note: 16e Lattice Sieve V5 (lasieve5f) wus are at this stage very quick to process, less than 1600 secs for 130 points.

Bad news.
Major corrupted file on G6p490 which got propagated to the backup before being discovered. Needs to redo up to 1500M (now at 255M).

Help requested, application lasieve5f.

Thank you in advance,

Carlos

At Sam's request, NFS@Home will factor the smallest five Bernoulli/Euler numbers. Details of the project are at http://homes.cerias.purdue.edu/~ssw/ber ... index.html

These numbers are below.
