And it fails again at 58% done. and never attempts to fold in the logs as we see it here.

As always a Log that contains the configuraation portion will give us the most clues why it might be doing this.

My guess and it will always just be a guess is that you have not found a way to be sure you are never folding on the Intel GPU.

Newer laptops use the 3d portion of the Nvidia control panel https://www.youtube.com/watch?v=HE6WA2l-14w

The underlying GROMACS science code has issues with large prime numbers (3 is never large, 5 is sometimes large, 7 is always large) and their multiples. In this sense, 13 is prime and 12 is not. So we recommend 12.

Is it not being interrupted because I have the gpu set to run "ON IDLE"?

From the top of the previous post:

Ah, ok. Will set cpu to 12. Any reason I shouldn't try 14 or 15?

If you are using 'on idle', the the above behavior may be what you want! (I am a 24/7 kinda guy and forget other kinds of folders exist)

14 is 2 * 7 and 7 is bad
15 is 3 * 5 and 5 may be bad

As the client gets newer, it does a better and better job of adjusting automatically. I hope someday not to worry about prime numbers.

I'd be happy to run it 24x7 but the system's unusable if GPU folding is active, which was kind of my initial problem. Then I found that "ON IDLE" maybe just seemed to transfer the work to the built-in GPU, which was then I added the second otherwise useless definition to make /that/ stop.

Seems a somewhat circuitous route. Am I doing the right thing?

Ah, /factors/. With you.

One of your log segments showed GPU folding, most did not. To be honest, what you posted was overkill, and I and probably others only looked at part of what you posted. For future reference to you and others that may come across this topic looking for help, we just need the first section of the log showing the system info and client configuration and enough from other log sections to show successful processing or a problem and the messages proceeding and following that error.

Now there are a few reasons why your system may be less responsive when GPU folding is active beyond what has already been mentioned. You have a mobile GPU and CPU, so I am assuming a laptop or similar non-desktop configuration. With both active you may be reaching the limits of the laptop cooling system and you may be experiencing throttling to stay within this limits. That will decrease responsiveness in a number of ways.

Using the "On Idle" setting for the GPU slot should help, but may only be part of the fix

As mentioned, 1 CPU thread is reserved for the GPU to handle processing,, on Full that will result in a maximum of 15. Medium reduces that to 14, assignments requesting for 14 CPU threads will always be reduced to 12 active threads. Depending on the OS, more threads than that may be associated with the CPU folding core, such as you saw in Resource Manager but the ones beyond those shown as -nt 12 in the log are not involved actively in processing the WU data.

Bruce suggested setting for 12 threads for the CPU folding slot, I am going to make a suggestion for 8. Here are my reasons. Your i9 processor has 8 CPU cores that provide 16 CPU threads through HT. The heat generated by the processor increases by a substantial amount when the circuitry involved in providing the virtual cores through HT becomes active. Your i9 processor is listed with a 45 W TDP, I suspect it has to throttle down to a lower clock speed to stay within that when the processor is continuously active while doing CPU folding. You may not be seeing much if any additional throughput using the 12 CPU thread setting as compared to just using the main CPU cores on the chip. Running at a higher clock speed may also help on responsiveness.

Finally, some of the logs show repeated requests for WU downloads for a Folding Slot 2 (FS02). I did not see that in any of the configurations I spotted while scanning through the logs. FS00 is your CPU slot, FS01 is your GPU slot for the GTX 1650M. What is or was defined for FS02?

This is the most recent configuration that you have posted:

Code: Select all

<config>
  <!-- Network -->
  <proxy v=':8080'/>

  <!-- Slot Control -->
  <power v='full'/>

  <!-- User Information -->
  <passkey v='*****'/>

  </slot>
  <slot id='1' type='GPU'>
    <gpu-index v='1'/>

This is the hardware that you have:

Based upon all the information provided above, this is what your optimized configuration would look like:

Code: Select all

<config>
  <!-- Network -->
  <proxy v=':8080'/>

  <!-- Slot Control -->
  <power v='full'/>

  <!-- User Information -->
  <passkey v='*****'/>
  <team v='10813'/>
  <user v='Ian_Worthington'/>

  <!-- Folding Slots -->
  <slot id='0' type='CPU'>
    <cpus v='8'/>
  </slot>
  <slot id='1' type='GPU'>
    <idle v='true'/>
  </slot>
</config>

You can change the 8 to any other number mentioned in this topic if you wanted too. I have removed the duplicate GPU Slot as that is unnecessary since you have a single GPU supported for folding.
