I'll take C209_122_107 next. See if I can get it to fit in 14GB.

66 hours to solve a 9.0M matrix, -t 4 w/ TD=116.

Code:

I'll try a 15e task: Taking C187_141_61.

By reducing the rels I finally got a matrix build (20M) with TD=140. ETA is 400 hours which sounds about right on a Core-i5.

What happened to C191 from aliquot sequence 3408 step 1668 in the 15e queue? Something seems amiss - the server appears to have stopped sending out work units.

Both 14e & 15e queues have stopped "pushing" out new WUs. No new WUs are being generated for some unknown reason.

Reserving 'C191 from aliquot sequence 3408 step 1668' on 15e, once it is fully sieved.

21.8M matrix of density 70; target-density was set to 130, but oversieving meant this was the best I could do. I tried reducing relations in the file to get a higher density, but longer expected-solving-times resulted.

Also, post #1890 contains the factors for 13_2_793m; it can be removed from the 14e queue list.

It's a problem with stats or work generator is broken? There are no "Unsent" WU's and only few hundrends "Pending".

About 204.8 hours for 19.56M matrix with density 134 (not enough relations for density 142) on 7 cores E5-2650v2.
