f18_199p1 has built a matrix. About 130 hours remain so I should have a result on Saturday.

I have added factors to the factor database

Please add 10M (?) relations to 12p5_795M.

That might be a bit over-sieved. Try reducing the relations such that you end up with 340-360M unique relations. This can be accomplished by stating:

./msieve -nc "target_density=130 filter_maxrels=450000000"

If you don't have enough unique relations then more are needed.

These quartic jobs tend to have a very high duplicate rate, such that 480M raw relations is a better estimate of what's needed.

That's a good point. That is why I emphasized unique as the keyword.

And so are the lousy large coefficient polynomials as I am currently working with one.

Done. Let us know if you need more.

I am wondering whether or not 11p8_287 also needs more relations added to it? I am not able to run at TD 120. Here is what the last bit of the log files says after running for 3 hours and 11 minutes. I am aware there is still over a million reels pending however I have run job 2 times once on 2 September and once on 4 September and both times it said the same thing

In saying that though the 2nd run was over 4 minutes faster than the 1st run so perhaps there will be enough reels pending. Please feel free to add more relations if it will help allow the job to run. Thanks.
