An update on zram-swap on a Pi running Ubuntu: Something about the Ubuntu kernel causes a race condition when setting up the zram device. This sometimes causes the script to fail.
This can be addressed by inserting: sleep 1 at line 105 of the zram-setup.sh file. The relevant segment of the file should look like this: if [ -b "$_device" ]; then If you've already installed it, it lives in /usr/local/sbin (or you could edit the file before installing). Absolutely well worth doing. The "Kraken" units didn't cause any crashes or invoke the OOM killer, even on the Pi 3s. That did become a problem when zram wasn't set up properly. Krakens on a Pi 3 with zram working would sometimes end up with one process running while others were suspended, but they would make it through. |

Any tech who can inform us:
----------------------------------------I see that we are nearing batch 100 000 for OPNG but now it has slowed down. Is batch 100 000 meaning that a specific target is coming to an end or is there a lack of batches after that? And what about OPN1 (CPU), what target are we crunching there and will it end at CPU batch 100 000 as well and then move on to target 3 from 100 000 - 150 000 or something like that?

Has work stopped again? It's been a few days since I've received anything at all.

It would be nice to have consistant work again. Not sure why you have to resurrect and old threat for this, but it might be worth to check in the "News" section once in a while, where it clearly states that MCM1 is currently the only project that is sending out work for now (and consistantly!) due to issues on the projects sides, and that thus OPN1, ARP1 and HTS are currently on a "planned hiatus"...Ralf |
