72.8 hours for 12.00M density-130 (140 didn't work) matrix on 7 threads E5-2650v2. Log (containing density-100 and density-120 filtering - I ran 120/130/140 in parallel and didn't keep all three logs) attached and at https://pastebin.com/MT99LRXT

I just took the first 400M relations rather than trying more complicated pre-filtering analyses.

OK, those runtimes are enormous, I have added a further 100MQ of sieving.

I hope there is some degree of 'running on this potato' in the runtimes ... 1300 hours would deal with a 50M matrix on my larger machines. If it's still >1000 hours for the job then I would happily take it over and run it on something chunkier.

32-bit jobs can sometimes take on a life of their own. My first two jobs on the current 14e queue both had initial ETAs over 1000 hours on my personal hardware. The first job is a bit undersieved, and the second is just plain hard (SNFS 270). I will re-download the C209_701xx141_5 job tonight when it has 480M+ relations and get an ETA, or several at ever increasing TD.

Many thanks for generating more relations.

With ~484M relations, TD=130 shows an ETA of 937 hrs. Not sure this time can be improved significantly. Reading in more relations and/or higher TD would likely help a bit but when traded against the time to optimize conditions, all under the cloud of possible oversieving lead me to think going with what I got might be best. But I’m open to investigating all scenarios if it’s helpful to others.

C212_157xx799_13 should be unreserved

 Test done, don't need to reserve this composite.
I double checked with Carlos - he confirms he is not working C212_157xx799_13. Can a gatekeeper edit the 14e queue to show this composite as unreserved?

I am going to have a guess and say this job took 4 1/2 hours. Starting the job with 8 cores and finished with 15 just to see if there was much time difference and there wasn't

Apologies if I can't figure out how to drive it and accidentally produce, for example, pastes that aren't world-readable.
