Whats with the huge disparity in points?

yes points assignment are very strange

By editing -nt 1 parameter in job file (in project folder) you can change CPU threads for WU. In my Windows PC with Xeon v2 and GTX1060 6GB using -nt 3 GPU usage jumps to 80%.
It should also dramatically decrease WU computing time.

can it be automised (in account settings may be?)

From app version 0.23 (Win) and 0.16(Lin) GPU's should be addressed correctly.

It just happen 1 hour after I put second card in another PC =))

oh.. just put 1080 in another PC and it download 21 ver.. on ryzen CPU project crash
19 ver is was good...

my main PC is still use 2 tasks on one card

And it is ok for now... Both doing its work, as single tasks doesn't utilise more then 50% of GPU...

But it's 2 gpu in this system. how to use all of them?

I'm working in this...
At the moment, I'm happy that application works...I will polish it today and try to find how to use GPU in better and more proper way.

Good.
I can confirm 2 completed and validated windows task's with very good points

Linux 0.14 and Windows 0.19 both uses AVX_256 instructions set...

but it isn't just OS support, cpu must support it as well

so main reason why we 0.19 crush where 0.14 didn't is avx256
my fx8120 and core i7-930 is out
is there optimization planed for this CPU's or we need to set "do not receive tasks" on this PC's?

still 0.17 ver didn't run GMX and have 0 load (on my amd fx8120 pc maybe it cause?)
0.14 ver autorestart over and over after i restart boinc and I kill this tasks manualy on 2nd PC
now on current PC I running 2 ver 0.14 tasks but only 1 gpu is loaded

I can create some tasks where 2 (or more if you wish) threads will be used to feed GPU.
Also, right now I'm compile application with AVX256 (instead of SSE4.1) support - this should also help.

I think better way is universal solution that will work on any common PC. Or it must be autodetect type of supported instructions and use best of them.
Also please chek work in system where is 2 or more GPUs
I just found that first my card is near zero load then 2nd at 40-60 range
when boinc say that running 2 tasks each on different gpu

Ok 2 of 3 my mashines run tasks with gpu but it very low load 5-15% on 1070 and above cards
third seems not receive task after I make project restart (update receive tasks again on 3rd pc gromacs ver 0.17 no gmx process no gpu use no cpu use)
1st and 2nd PCs have 0.14 ver with gmx that take slight gpu use and 1 cpu core)
please pay attention that cuda work different on windows 7 and windows 10 PC (know it from mining threads)

oh all my windows pc's with NVidia gpus stop amicable and launch dd gromacs. and it's fine. but gpu use 0
boinc think that task is running but is 100% buggy (slow speed and 0 use of GPU)
please give some advice

My windows 10pc just start cuda gromacs task
and as I can see it didn't do anything
gpu use is zero after 20min completed 0.6% on 1080 card
in process tree there is NO gromacs process

may be additional software must be installed like Linux mashines?

Post:
All my windows machines have problems with download of vina WUs. All are checksum errors.
I see that there are very few or no vina WUs at all. Can the project not handle all the computers requesting download?
Do others have the same problem?

yes, checksum errors again
