The biggest mystery for a C175 file is the number of relations to target; but since you have an army of sievers and not much matrix power, I put the relations count a fair bit higher than I think strictly necessary. I think you could get away with 250M relations, but 270 should make a much nicer matrix.

Thanks! I will start one this morning. The "farm" will be short two of its major contributors for now. You use CPU timing data instead of wall clock, don't you? So, the lack of these two machines shouldn't skew the data too much?
As to my msieve testing, I did get the option to work using quotes:
Code:
../msieve i comp.n s comp.dat l compmsieve.log nf comp.fb nc1 "target_density=100"
But, the run failed to build a matrix. I'm trying "=90" to see if that may work. It's taking about two hours per test run. I'm starting each from scratch for consistency, so each run begins with harvesting the CADONFS relations and running them through remdups4:

Tue Apr 7 01:12:22 2020 too few cycles, matrix probably cannot build
I'm guessing this is quite short and probably would take a lot of raw relations to come up with enough, but am totally outside my knowledge base at this point.
Here's the full log (excepting some error 1... lines):

I intend to keep this full set of relevant files and maybe I'll add some more relations later  maybe even do some more Colab playing.
