Linear algebra reservations, progress and results

Yes, as to 14/32 I'm now in the 'don't do it' camp. Feeding the grid is not sufficient reason to burden the postprocessing folks, not to mention forcing the sievers to do non optimum tasks. And feeding the masses does not seem to guarantee them staying around - the throughput of NFS@Home has steadily dropped for the last few days, and most of the sieving resources have shifted to 16e (though maybe this is Greg shifting things around behind the scenes). This despite sufficient queue length to keep the grid fed. Maybe there's another challenge somewhere else. Regardless I've spent the last month optimizing my polys/siever choices and I will stick with them. And ECM is still a big part of the process - I've got lots of partial t60 work ahead of me. Happy factoring!

What is happening is that Gridcoin CPU power is deployed onto SRBase and Syracuse University is on Universe@Home pausing NFS help since 27 Nov. Also there's a challenge going on at SkyNet POGS, SETI.USA and Gridcoin are there.

In the meantime Team Norway and L'Alliance Francophone joined the 16e effort but not enough to reach the daily 80k wus from Syracuse University. 14e and 15e sieve is down due to Syracuse University pause but it will give us time to clean the post-processing until it ramps up again, hoping within a week or so.

Good to hear they should be coming back soon.Yes it will be nice to work through some of the backlog. I'm thinking I can postprocess some of the waiting 14/32 jobs but that remains to be seen. Trying to procure a big memory machine (32 Gb) for 15e work but SWMBO has not yet authorized it.

Same here. The beast would be:

So very jealous of this potential rig. Perhaps one day.

C177_HP2_4496_300 LA has been started (density of 130) and will done in ~69-70 hours, depending on how long square root phase takes.

Bad news, I've just lost my laptop cooling pad therefore I'll need to release all my reservations until I sort this issue out. Maybe it's a sign to buy new rig. I'm very very sorry.

Reserving C186_138_79 (14e).

C277_150_122 is now actually started (on a six-core rather than trying MPI, since the matrix is 'only' 24.54M), ETA 19th December

Same model new one costs £55!!! Remember to buy this one by one third of the price.

I'll take C194_142_70 next.
