Maybe it's time to remove "mini" from the app name... ;-)

On the serious side, considering that most PCs are still sold with 8GB or less, maybe creating another app name for this type of work would indeed be a good idea, so that only people who have much RAM can activate it in their profile while others won't be stopped from getting work (if that can't be solved in another way).


I decided to buy another of my favorite brand of computers yesterday. They didn't offer any with more than 32 GB that fit my other requirements.

You generally need server class hardware to get more than 32 GiB of memory. <begin wry humor>And, since the project shuts you down if you fail for ANY work unit, you need 60 GiB of RAM per core. That's 240 GiB for a quad core. You can get that with AMD Opterons or Intel Xeons using registered ECC RDIM's. This is not a viable approach for most volunteers.<end wry humor>

That aside, I had to manually update 8 stuck machines yesterday. I was about to say that I didn't have to restart any today but just found one on a 20 hour backoff. Fortunately I increased my buffer from a half a day to a full day to give me time to find them before they run dry.

Oh, and why is it called "mini rosetta?" See https://www.rosettacommons.org/content/what-minirosetta

Two of my systems have started intermittently falling into 'project backoff' for 10-40 hour periods after getting this message in the logs (If I go and do a manual 'request new tasks' they successfully get more tasks but I noticed because their work queues dry out:

Is this perhaps a result of higher 'memory requirements' attached to some of those jobs? If so, no worries, I'll just keep an eye on it until that batch finishes :)


I found two of my machines in that state this morning and several yesterday.

That machine had 18 hours of backoff when I found it this morning. it still had one work unit running out of four cores.

This machine was completely out of work when I found it at the same time with over 24 hours of backoff. It got work as soon as I manually refreshed the project. My priority 0 backup project was not getting work either, but that never seems to work..

I don't mind not getting a work unit that needs 60 GiB of RAM but please don't refuse to give my meager machine more bite sized work just because of that.
