Status Update
 

I’ve been away for a couple of weeks, but had set up all my reserved numbers before leaving. Unfortunately we had an early snowstorm (along with the eastern half of the US) that caused power brownouts and blackouts. Despite some buffering and backup power, my best machine got fried. It’s in the shop now, I am hoping at least some logs can be recovered for some ECM work I was running. Fingers crossed. ETAs follow:

54441_249 - factored (see above)

C200 from 135^88+88^135 - 19 Dec

147^53+53^147 cofactor - 22 Dec

148^83 + 83^148 cofactor - winter (33-bit job, ETA subject to change depending on load)

C224_122_119 - ? (Work likely lost in crash, 6+ weeks to rerun)

C231_133_73 - ? (Work likely lost in crash, 3+ weeks to rerun)

C202_137_75 - winter (33-bit job, ETA subject to change depending on load)

C184 from L3865B - ECM should be completed 20 Dec (delayed a bit by crash)

Reserving Lucas(1324) though I won't be ready to start the job until Jan.

Suggestions for a job for us to do would be appreciated. We are not bothered if the work takes an extra long time.

Thanks!

16GB is enough for all but the very-largest 15e jobs (which, on two cores, would take many months anyway). If you try some of the smaller 15e jobs (judged by size of Q-range, a very rough proxy for difficulty), you should spend less than a month on each job.

Odd that. Did you get a plethora of errors during nc1? The fact that you got into nc2 implies a feasible matrix was built, but maybe something went horribly wrong.

What was the command line you used to start this job after the dataset finished downloading? Did you have to make several attempts using various values of target_density to get into nc2? Posting the log file might be useful, assuming it’s not too huge to post without editing out a lot of error messages.

[QUOTE=swellman;476762]Odd that. Did you get a plethora of errors during nc1?[/QUOTE]No errors other than it rejecting a few bad relations.

I’ve begun downloading this job on an attempt to duplicate Xyzzy’s issues, or punch through the factorization with a 32Gb machine. Will also first attempt to build the matrix @TD=130.

I think the part of xyxxy's log in an above post indicates the matrix was not at the density requested; this is likely oversieved. Reducing input relations a bit should help with the matrix.

Reducing input relations a bit should help with the matrix.[/QUOTE]If this is the case, can you just chop out a bunch of relations or do you have to remove certain ones?

What line from the log file gave you this clue?

I’ve built a matrix @TD=134, though it’s too early to know if it’s stable. 9.2 Mb matrix, which is currently 0.7% complete and has an ETA of 342 hours using 4 cores +4HT on an old Asus gaming machine with 32 Gb memory.

You said you set TD to 120, but the snippet of the log you posted (in the other thread, about errors) showed a density of 72 or 74. msieve has a flag to truncate the number of relations, called filter_maxrels.

Probably still premature but I think you will need to extend the sieve range for the composite, am I right?

In the meantime I’ve requested Jeff if he would compile msieve taking advantage of large vectors for linear algebra phase as per this thread: [url]http://www.mersenneforum.org/showthread.php?t=22386[/url]

There will be a fortnight or so's delay for F1361; it uses 21GB of memory which turns out to be too much on a 32GB machine on which I'm building a several-million-line C++ codebase repeatedly, so I'll have to move it to another machine which is currently busy. The job will take about a month so the delay is immaterial.

Looks like the GCW number (9_266+.C255) in the 14e queue can use a few more relations. Currently the 32-bit job is at 345M.

That’s why I’ve chosen to post process the one queued on the 15e queue. Paul needs to estimate more relations up to ~450M.

After remdups, roughly 385M unique relations remained. TD 134 produced a 20.1M matrix of density 71. So, I reduced relations available:
375M relations produced 19.35M of density 87
360M relations produced 18.8M of density 99
345M relations produced 18.5M of density 109
330M relations produced 17.3M of density 134
332M relations produced 17.22M of density 134
I used the last matrix. It consumed 9.1GB memory according to "top".

I don't think any 32-bit job needs more than 450M raw relations, and many of these will build nice matrices with 425M. We're oversieving by 15% beyond the relation set that will build 130+ density matrices, and inattentive postprocessors will waste substantial time solving the bigger matrices that result.

Nice finding, consistent with your earlier work. I know that when posting “my” jobs the target number of relations is always high, 490-500M for 32-bit jobs. Future requests from me will target 450M going forward (I have few 31-bit jobs in the hopper, all GNFS C175-182 currently).

It's worth pointing out for posterity that this job began with 484M raw relations; my log does not show that since remdups was run before filtering. The duplication rate of the highest/last Q is usually higher than the lower Q values, so it's reasonable to think that 410M raw relations would have yielded the 330-335M unique relations needed for the desired density of 134. This was a GNFS-183 job, so 175-180 jobs should aim for 400M or 410M raw relations.
This poly may have had unusually low duplication of relations, but it's a safe bet that a smaller job won't need more raw relations.

To replace it, it seems that Phi_3(Phi_13(4611351)/small)/3 is unclaimed? Should be finished quickly at any rate. Edit2: I believe that's a typo for 44611351 ??

Edit: Can we create a new naming scheme for all the jobs? Having [i]all[/i] of them start with C1**_numbers_numbers isn't really that easy to tell apart. Yes we can easily deduce which are XYYXF and which aren't, but I still think we can do better. For instance those XYYXFs, instead of being C***_***_**, could instead be XY_C***_***_**, while the OPN jobs, instead of being C***_****_* or with a few x's in the middle, could be OPN_C***_base1_power1_prime1_power2_prime2..., which for instance would mean that the job I just claimed would change from the current C160_702xxx179_3 (which is remarkably opaque and basically impossible to correlate with its status page name) to the more useful OPN_C160_[URL="http://factordb.com/index.php?id=1100000000126448679"]44611351_13_3[/URL]_[URL="http://factordb.com/index.php?id=1100000000438761360"]3_2[/URL] ? (That is, start with 44611351, take Phi_13 of it, take the third factor of that as the next base, Phi_3 that, and then the C in question is the 2nd factor of that.) Not only is that name easy to correlate with whatever's on the status page, but it's also a bit easier to trace the actual n in question than just throwing "small"s about everywhere in the name. Similar schemes can be created for other projects, but even just adding the project_prefix before the composite_size would be very useful.

Did it build with density 128, or something lower? Oversieving doesn't cause filtering to fail (usually- the full data set here would cause it to fail!); it mostly causes larger and slower matrices at lower densities than requested.

If your matrix has density below 110 on your log, I'd try filtering again with maxrels = 450 or 445M. If it's below 95, I'd try 440 or 430M.
