1) Message boards : Questions and problems : LHC@Home, GPU, and BOINC ProjectList (Message 93183)

It's a very simple search routine. I dare say there are other cases where projects are using what they consider to be "innocent" application names that trip the "ooo, there's a ?????? application" by the BOINC processor type routine. Most of the time it is just a simple annoyance, but there are times when it gets a bit beyond that. Just be thankful the project "knows the truth" and doesn't send work out for a non-existent application.

It is really down to the particular project(s) you run.
Some projects have already developed multi-core applications, many have not for a variety of reasons, not the least of which being time to develop and test - the project needs to be certain that each and every application it distributes returns correct results (and that includes errors when a data-set has poor quality data that falls outside the valid range of values).

4) Message boards : Questions and problems : Running BOINC Project (SETI@home) for 48 Hours Killed My Galax GeForce GTX 1650 4 GB GDDR5 GPU (Message 93077)

I've been running SETI@Home for over ten years on GPUs. In that time I've had two "dead on arrival" - GPUs that failed within the first couple of days of 24hrs/day operation. One suffered a fan destroying itself, and the other "just failed".
If we lay aside the two GTX690s that got drowned by a domestic water pipe bursting and spraying water all over them I've had another three fail, after several years of 24/7, but quite a few fans have failed - again after years of service not hours/days.

I suspect your GPU suffered a premature failure - it does happen, but is very rare.

What operating system are you running? - Windows has a nasty habit of updating GPU drivers with ones that don't have the parts needed for computational work. Two actions - first stop Windows updating your drivers, and second update the drivers from the nVida website - see the next note about versions.
Have you recently updated the GPU drivers using the very latest from nVidia - there are reports that these are "not as good as they might be" when it comes to computational work. This has happened before, GPU driver updates are most frequently associated with the performance when gaming. If so, roll back to one no newer than 430.x
In both cases you need to do a "clean" installation - this is a somewhat hidden option, buried beneath the "advanced installation" button. When the installation is complete do a re-boot to ensure you are using the driver you just installed, not the "old" one that might be lurking around in memory.

For one thing - the date of the last benchmark is "impossible" - it's 49 years ago!

The answer depends on which projects you want to do work for. For some projects (e.g. SETI) a recent nVidia will be best, while for others a recent AMD will be best. Take a look at each of your projects' forum and see what they say.

At Dark o'Clock this morning there was a really cracking thunderstorm in the Stone/Stafford area, along with a copious amount of rain.

About half an hour ago the cruncher in front of me reported SETI was "down for maintenance", but it now back - I guess someone administered the kick of life to the servers.....

However the server code has not been written around MariaDB so someone would have to go through that and resolve all the inevitable warnings and errors that would occur when changing the db engine.

You are describing the symptoms of hitting a hardware wall.
A couple of years back I was involved in the management of a high-GPU count computer - it had 64 GPUs. During the development it was found that use of "commercially available" risers and the like was fraught with problems due to the poor standards of manufacture of these devices (coupled with really diabolically inconsistent motherboards). Out of batches of 16 risers, of various types and manufacturer the average failure rate was in excess of 50% during the burn-in period, and a further 50% of the survivors failing the next phase of testing. If you care to look though the SETI message boards you will see a user "Tom" who describes everything you are talking about in his endeavors to get a moderately high GPU count of about a dozen stable - I've lost count of how many risers, splitters and motherboards he has gone through.
On the other hand "we" are in the middle of commissioning a "bit of a beast" of a computer with 256 GPUs. As a trial a 64GPU segment of it was loaded with BOINC, which detected all GPUs first time, and "demolished" the thousands of tasks thrown at it. Because these tasks were duplicated from other computers neither they, nor the computer concerned will ever appear in the list of crunchers.
So no issues with BOINC not supporting large numbers of GPUs - with a dozen or so you aren't anywhere near the limits of BOINC yet.

Daily quota are normally set by the servers so there is nothing you can do about them.

Some spliters do have external power lines which help the situation by cutting the power lines from the "plug" and inserting the feed from the external supply in their place.
But, as others have found the quality of many of those spliters and stand-offs is not that high, and price is not a good guide to quality :-(

From what I gather the pool collects all the credits you earn, your will be unable to manage the share between processing their coins and your chosen projects and you can't leave the pool until you have processed sufficient coins. Further the "real" value of these coins is so low the amount donated to the project(s) they sponsor is pretty small.
I slightly disagree with Les - "You have been assimilated".

Credit award, both policy and magnitude, is not something done across the board by BOINC but is very project specific so why not ask over at SETI?
