[QUOTE=swellman;578880][QUOTE]What target_density did you specify when starting msieve? Or did you just go with the default value (TD=90)?
[/QUOTE]

There appears to be plenty of relations for a job this size but who knows with the recent tsunami resulting from the pentathlon.[/QUOTE]
I initially tried with TD 110 then 100 and tried your suggestion of 90 but still no luck. Please see complete log below

Jarod -

I bumped Q up to 50M. Let us know if that’s not enough.

Thanks for adding another 50M to my number. I will let you know if I need more added to it

I have to agree the pentathlon has had noticeable effects i.e. stopping results for smaller numbers been sent out for a day or more. I hope it was successful for everybody involved.

Looks like you are missing part of the dataset file. At the time, the server was reporting about 65M rels but Msieve only read in 52M. If you re-download the new dataset it will have about 75M records. This will cause an over-sieve condition, which will need to be addressed in a different way.

I suspect a portion of the generated relations never got into the data file during hurricane Pentathlon but you might be right.

Jarod - just watch for a lot of relations (i.e. an oversieved condition) when you next attempt this job. If so, use the filter_maxrels= flag when invoking msieve.

[CODE]
msieve -v -nc “target_density=110 filter_maxrels=65000000” -t 4
[/CODE]

Or similar (if needed).

I have a feeling more rels needed to be added. There are 582,937 rels remaining to come in. Please see attached zip of several failed runs most of them TD 90
Thanks

Jarod -

I just downloaded and got this job into LA. See attached log file. I have stopped the job now - it is yours to factor. But there are sufficient relations now.

Suggest you delete the current .dat file from your local machine and redownload it.

You may want to limit the number of rels handled in filtering (as discussed earlier in this thread) to avoid an oversieved condition.

Thanks for the information. I will give it a go again in 6 or 7 hours. I wasn't able to find any commands on how to "limit the number of rels handled in filtering" (in the discussion earlier in this thread) if easier feel free to send me a PM
thanks
