Assuming the current filtering run (2.59B uniques, target_density=140) succeeds, I will probably start LA afterward. The size of the relations file is becoming the issue at this point.

Not sure about the target; something in the 90M to 100M range would be nice. I'm also running up against the sheer size of the relations file, which is now about 200GB even gzip'ed.

Currently running the filtering with 2.59B uniques, and target_density=140.

Previous run (2.47B uniques) managed to get the matrix size down to 125M.

I'm willing to try culling the 36-bit large prime relations. Would you be able to construct the "grep" command? I don't quite know the msieve relation format well enough.

I've got it running now. The output is currently at:

Does that ration of "bad" to "read" seem reasonable?
