Nice work on the stats. How can I tell how much I contributed? (I'm sure it is less than 1%.)

Yay for Sethstats! Also, nice chart for yield per WU.
Boo for learning how little I contributed to the job, but seeing how slow (in rel/sec) my machine sieves is a nice reminder to maybe go Ryzenshopping in 2022. What should our target be for matrix size to say "good enough, let's stop sieving and run the matrix"? 55M? 50? The C207 team sieve was 72M matrix using msieve. Our uniques ratio had gone to hell because we shifted from I=16 to I=15 too early, so sieving more for a smaller matrix wasn't productive.

PM'ed you. For the final stats, I will add names of those who were okay with this manually and strip out the clients manually or something like this.
Thanks. Quote:

There is no need for check_rels. Msieve will check the relations itself. You may end up with some bogus bad relations where the joins between the original *.gz files were; don't worry, you aren't losing any real relations. CADO does not put free relations in the upload directory, so there won't be any for you to remove. Msieve will add them the first time you run filtering. Finally, make sure to reverse the signs of all the algebraic coefficients (A6 to A0) in the msieve.fb file, because otherwise msieve will complain about the negative leading coefficient when it finally gets to sqrt.

Of course I should have said "A5 to A0" rather than "A6 to A0" in my previous post. Not that it matters much.

An alternate I use for the relations:
Code:
for i in <directory/relsprefix>*.gz do cat "$i" >> total.gz done zcat total.gz  remdups4 1000 >msieve.dat I also wrote a routine to swap the poly to Msieve format, but I believe that CADONFS provides one as well. From the CADONFS README.msieve: Code:
1) Create a file msieve.fb, which contains: N <number to be factored> R0 <coeff of x^0, rational side> R1 <coeff of x^1, rational side> A0 <coeff of x^0, algebraic side> A1 <etc> A2 <etc> A3 <etc> A4 <etc> A5 <etc> This can be done with: $ ./convert_poly of msieve < cxxx.poly > msieve.fb Thanks, Seth, for a great resource and helping it work for this project!
