In this folder Program Data-->BOINC-->projects-->www.gpugrid.net folder gpu_usage I do not find any files or settings related to gpu_usage and cpu_usage.

By default there is none.
Here's how to create one: FAQ: How To create and use an app_config.xml file in Windows

When looking at process explorer I can not find anything matching the GPU Grid or the task name.

You should look for acemd.848-65.exe

The old app will become obsolete only if the CUDA 8.5 app will be faster on older cards too, in this case it will be worth to update the driver for older cards.

I think Pascal has the same basic architecture as Maxwell, so with a little luck, the CUDA 8.5 app will show improvement there too. That would be a nice bonus.

Provided that improvement will exceed the difference between non-WDDM and WDDM Windows.
As there won't be new drivers for Windows XP any more, if the efficiency improvement of older cards is worth it I will convert all of my hosts to Linux.

one thing i did change for POEM was downgrading my drivers for my 980 ti from 372.70 to 362.

v362 works but v359.06 is noticeably faster here. There's going to be a new app soon. Not sure what that will require.

The new app will obviously need the latest driver for the latest cards.
I think the older app will be sill in operation for the older cards and hosts after the release of the new app.
The old app will become obsolete only if the CUDA 8.5 app will be faster on older cards too, in this case it will be worth to update the driver for older cards.
We'll see.

You should check the access rights of the user who runs BOINC manager on that folder. (The command prompt runs under a different user)

I would say better less than 100% efficient but to have at least something.

A fellow cruncher called the CUDA6.5 client "ancient" in another thread. Other projects go the way according to the "to have at least something" mentality, resulting in CUDA3.2, CUDA5.0, and CUDA5.5 apps. What would that fellow call those clients? This project has chosen the other way: to have state of the art app (because it's using a proprietary code provided by Acellera, so it has to be competitive). To have clients serving both mentalities requires doubled development teams, but it's gratifying to have at least one such team. Thus there always could be a group of people who can pick on the way a project goes, but I'm quite satisfied with the way this project goes, however the pace could be faster, but it's limited by 3rd party (NVidia).

...is there a reason why the GPUGRID code for NVIDIA GPUs will not run on the new Pascal cards?

Judging only by the error messages the app throws, it uses different libraries for different Compute Capabilities (to maximize efficiency I guess), and the one which is necessary for CC6.1 is simply not present in the CUDA6.5 code (obviously because there was no CC6.1 back then when the CUDA6.5 came out).

Is the hardware not backwards compatible that it can run older code

They are backwards compatible, and they could run older code.

... it can run older code like other projects such as Einstein or POEM which have been working without the release of CUDA 8.0/8.5 support on the 1080/1070?

Probably the CUDA 6.5 code could be made to work on the Pascals, but when you do that, your app could be missing a significant part of the hardware improvements, thus it could be slower and/or less energy efficient than a new code.

In the logs of all your invalid tasks traces of dirty shutdowns are present:

# GPU 0 : 82C # GPU 1 : 79C # GPU [GeForce GTX 980] Platform [Windows] Rev [3212] VERSION [65] # SWAN Device 0 : # Name : GeForce GTX 980 # ECC : Disabled # Global mem : 4095MB

while a normal shutdown looks like this:

# GPU 0 : 83C # GPU 1 : 80C # BOINC suspending at user request (exit) # GPU [GeForce GTX 980] Platform [Windows] Rev [3212] VERSION [65] # SWAN Device 0 : # Name : GeForce GTX 980 # ECC : Disabled # Global mem : 4095MB

Notice the missing (3rd) line explaining the reason of exit in the first case.

... GPUGrid tasks are already configured (by the project) to be reported immediately, as can be seen by inspecting a COPY of client_state.xml and seeing <report_immediately/> set for each GPUGrid <result> (task).

Thanks Jacob, I didn't know that it'd been set by the project.

after a quick review of all the above comments, my question is:

which time span is being taken to determine the 24-hours limit or the 48-hours limit with regard to the extra bonus:
from the time when the WU was downloaded vis-a-vis the time the finished WU is being uploaded?

Yes. Uploaded & reported, so the <report_results_immediately> option should be turned on in the cc_config.xml file.

If so, in the BOINC computing preferences, under "store at least ... days of work", the smallest value possible should be entered, I guess.

Yes, so you can set it to 0. In this case the manager will ask for new task only when the actual one is finished, so there will be a little idle time between the finished task and the new task. It is advisable to have only one another GPU project on such hosts with 0 resource share to avoid the host running completely idle while there are no available work from GPUGrid.

I am asking this because one of my hosts (GTX750Ti), for example, crunches the current Gerard tasks in about 23,4 hours.
However, I did NOT get the 24hours bonus, probably because, as a result of my settings (0,2 days), this WU was downloaded a few hours before the previous WU got finished and uploaded.

Is this right thinking, or am I missing something?

You're right.
