And I've edited mine. It probably doesn't matter for personal use, if you always keep the build API pretty close to the version of the BOINC client you run - but worth knowing about if you build for wider distribution.

If you can convince me Jason was wrong for wanting to stay around 6.x, and Petri is wrong for continuing to use 7.5, I might change it. I did try 7.11 for a while, but then decided it would be best to use what Petri is using.
If you check, Jimbocous is running 7 GPUs on an older system probably not designed to run that many GPUs. On the Systems not designed for it, you hit a wall around 7-8 GPUs, especially if you are using a PCIe switch. Ask Tom M about that. If you want to run that many GPUs you need a board designed for it, either an Expensive Server board or a relatively cheap Mining board. For the price, the Mining board works for me.

BTW, ASUS is Still updating their Mining board, look what the Updates have mentioned;

some people just have an "if it ain't broke, dont fix it" mentality. works fine for a while, until the world moves on around you and your outdated platform starts to break. Notice all the 6.x guys recently suddenly asking why they can't communicate with the project due to outdated security certificates. needing to jump through hoops just to keep it going, some not even able and being forced to upgrade. you yourself have even commented on petri's idiosyncrasies. nothing wrong with it, and petri is more than capable of handing any issues that might come up. I fall into this sometimes since my systems are so stable, i usually don't do any unnecessary updates, which keeps me from having a lot of the issues like systems breaking from a driver update or something similar. but I do it within reason, and update after the seas are calm. same reason i've avoided the Ubuntu short term releases, but I will move to 20.04 LTS when it's proven stable.

my 7x 2070 system on the z270 platform is very similar to your 14-gpu B250 mining system in the way they work and components used. total system cost is likely within a few hundred dollars. doing more work with half as many cards, less power draw, and less headaches. I'll take that any day.

I may update that system soon since I just replaced my z370 based test bench with my backup board for the watercooled system. I could take the z370 board, drop in a relatively cheap 12-thread CPU, and add another GPU or 2 to the system. still undecided.

Message 2032701 - Posted: 16 Feb 2020, 18:50:59 UTC - in response to Message 2032699.  

I think Jason was hoping to persuade BOINC to leave runtime estimation as a client function, through submitting code (which I tested for a while in a working client) to maintain separate DCF values for each application version. I would agree with him, because the current runtime estimation server-side code suffers badly from boundary-condition errors (new installations and new application versions) and from slow response times.

But that was 10 years ago, and the world has moved on - we are stuck, for better or worse, with CreditNew and the associated runtime estimation model.

I would suggest that it's better to stay in touch with the newer BOINC developments: after all, the SETI (science) applications have no productive purpose outside the BOINC framework, and in my view it's better to work with BOINC than to keep re-running ten-year-old battles against it.

It was meant to provided user level support so people could migrate to a more productive platform ... So please remember the KISS principle ...

First I would recommend that you upgrade to the 440.xx drivers, so that you can use the CUDA 10.2 builds. it'll be a benefit for your Pascal and Turing based cards.

after that, you can get Tbar's V0.98 builds here: http://www.arkayn.us/lunatics/BOINC.7z
this is a whole "All-in-One" BOINC package, you do not need the repository install, and should remove it before using this.

if you want to try out using a newer V0.99 mutex enabled build (pre-loading a second WU, eliminates downtime between WUs) you can use my build here: https://setiathome.berkeley.edu/forum_thread.php?id=84933 but I would recommend waiting a few hours. I just made several new builds that should be faster and give people more flexibility on supported hardware, running them through my test suite now.

I would download Tbar's package there first and get up and running with it. then after I gather my test results you can decide if you want to modify it with a different app.

The system I am discussing has 5 GPUs. Paradoxically, the one with 7 GPUs doesn't seem to have these issues. And the wall on those HP mobos is definitely 7 GPUs.

That's a nasty one, but - I think - different.

The first task wrote
<message>Process still present 5 min after writing finish file; aborting</message>
and then went on to write a normal std_err, right down to 'called boinc_finish(0)'
...

As the comment says, "it must be hung somewhere in boinc_finish()" - very late in boinc_finish, if it wrote the file over five minutes ago. But it would be a normal part of BOINC's exit function to copy std_err.txt from the slot folder into client_state.xml, so that it's reported...
Point being that it seems that this is where the driver gets crashed, not just the client.

@Juan, had another one this morning, but sorry, wasn't awake enough to get the slots info you asked for ... I'll keep trying.

If you've been following my discussion of this, you'll note that the overflows are all subsequent to the initial failure, as a result of the NV driver no longer knowing the card exists.

Have you tried it with a different driver? I see 390 is in the repository, and that will work with cuda 9.0. I remember running 396 for quite a while if that driver is possible for you.

This will probably be Invalid. The machine is using a new BioStar Mining board with an eBayed i5. It's the same machine I ran the Development version of 20.04 on a few days ago. The MP version failed in the Benchmark App, it ran through in seconds without finding any signals, so, I didn't try it in BOINC.
