I always use scp when available, perhaps my expectations re. fs-path handling have been colored by that. But on this particular server (or perhaps my remote-access privileges to it), only ftp is available.

Hadn't thought to ask that myself. If it had come to mind, I would have. It will be useful when we find the next candidate prime.

PRP-proof support will be in v20, yes. I am alas behind the curve there - between the pandemic and a series of non-life-threatening but still frequently day-week-and-month-ruining health bugaboos, this year has been one of continual annoying distractions. And EOM my housemates-of-2-years (young professional couple who just bought a starter home in the area) are vacating the MBR suite of our large shared apartment, so I have tons of busywork to do getting the place ready to show to prospective renters. What a year...

My one main concern re. PRP-proof support is that it appears that the memory needs will relegate many smaller compute devices (Android phones, Odroid and RPi-style micros) to doing LL-DC and cleanup PRP-DC. It's downright undemocratic elitism, it is. ;)

Low power proofs are better than none. Standalone devices could drop to 6 (or even 5 if necessary?) and still save ~90+% of a DC.

Per https://mersenneforum.org/showpost.p...5&postcount=46 power 7 takes 1.5GB disk space for residues at 100M p. Since Odroid is Ubuntu and GigE, why not pile residues on a network shared drive and then clean them up after the proof file exists? A Droid, Pi or phone farm could share a single TB drive.

Right is more important than soon. And life happening affects how soon is practical.
