Anyone know a way to make a GPU run two different projects at the same time???
E.g., run GPUgrid & Einstein on the same GPU. Or, GPUgrid & a different GPU project, in case I run out of Einstein it can run Milkyway.

Could probably do it with a app_config.xml and limit GPU to 0.5 with a full CPU then using a <max_concurrent> following each type of work unit to 1 so only 1 work unit runs on the card.

However, I would advise against it.

You risk causing errors by mixing different projects on the GPUs.

Best case is you slow down the processing on the card by more than 50%.

Hi PappaLitto, You answered another question I had. So I have SWAN_SYNC enabled on a Linux computer and you're saying there is no need to say this:

I took a look at your computers to find one with a similar setup to one of mine. You have a host with 2 1080s and Linux Mint, similar to mine with Mint and a 1080, both with SWAN_SYNC (SPIN) enabled. I compared a recent set of two PABLO...MOR18 WUs against my most recent of the same type.

Your times were about 37000 and 38000 seconds each. Mine was just under 17000. There is no way this is definitive with such a small sample and also not knowing what else was running on your GPUs at the same time. However, it points out that it might be worth your effort to check out only running one GPUGRID WU with SWAN_SYNC enabled and compare overall points/time.

For what-it-is-worth, I do run two MilkyWay WUs at at time -- still better results. I think it has to do with the fact that during a Milkyway run, there are 'down times' on the GPU (watching on a Windows 10 setup with Afterburner) which get filled up when running two with offset start times.

I couldn't think of a way to make that work. Say a rig has two GPU cards. I get any and all of these possibilities at some point:
GG+GG and GG+GG
GG+MW and GG+GG
GG+MW and GG+MW
MW+MW and GG+GG
MW+MW and GG+MW
MW+MW and MW+MW

GG = GPUgrid WU
MW = Milkyway WU

I'd like: IF WU1=GG THEN WU2≠GG

I'm also curious to see if this is possible as I tried to do this a long time ago.

I still wish BOINC allowed this:

You're far from the 1st user to want some type of slot system for processors within BOINC kind of like FAH. I don't know where the suggestions are going but I made it here:
https://www.cpdn.org/cpdnboinc/forum_thread.php?id=8799

My guess it is really just the BOINC Mgr even though the client was mentioned.

I read some where that there's no dedicated BOINC developers any more. I don't know. BOINC probably has a forum that may be the most appropriate place to post my Wish.
I posted it here hoping that Richard Haselgrove will see it and pass it along to his BOINC buddies. He's the best BOINC-connected person I've come across in the various forums.

Re multiple projects on one GPU. In linux, we can run nvtop and see how much memory is being used. So is there a method setting GPU memory usage per task? Even if true, are there multiple engines, like multiple cores on the CPU, where both WU's run literally simultaneously?
