Message 36 - Posted: 1 Nov 2021, 16:45:04 UTC - in response to Message 35.  

hello
on one of my PCs
Intel(R) Core(TM) i7 CPU 870 @ 2.93GHz [Family 6 Model 30 Stepping 5]
(8 processors)
computer 94
I received 152 WU at the same time, is this normal?
thank you


That is probably because the initial estimated run time for the tasks is only about 15 minutes, even though they actually take several hours to complete.

I've noticed problems.
I increased 10x the possible execution time.
I set it to 40 credits per WU at this moment.
There is a new specification for tasks in the new series "TESTS_1A_T..."


Thank you for increasing the time limit and the credits. That will allow more computers to complete their tasks successfully so that you can see what the time limit really needs to be based on actual completion times.

I got a few to complete and validate. These were on 4 core i5's. Seemed to like those better than my HT machines.

Mine starting to complete and validate after 4 hours 7 minutes.
The 40 credits are better than 8 but still the worst paying CPU project, a low paying project like TN-Grid gives 137 credits for 3 hours and 15 minutes on the same machine.

Haven't seen any issues with tasks using more than 100% CPU.

We will increase the credits per hour to the appropriate value.

Does this app use any extensions like AVX/AVX2/AVX-512 if available?

I'd say the worst was the 2nd batch of tasks from Ramanujan Machine for 8-9 credits. But yeah, pretty low.

That was just an error by the Admin who is new to BOINC rather than a deliberate act, I would hope and expect credit levels to return to normal levels when more work is released.

CPU temps say no. :)

Michael Goetz: you are correct.
Instructions AVX/AVX2/AVX-512 are not currently supported.

For a computationally intensive project, 40 credits for six hours of work is a bit paltry.
My 32-bit Linux computer normally earns about 20 credits per hour, so it really deserves to be granted at least 120 credits.

Doesn't the Boinc server software include an automated credit system that is based on work done? Can this be used for this project?

As an aside, when I attached a 64-bit computer to this project, it received a 32-bit application!
My other 64-bit computer was given both 32 and 64-bit versions of the app.

The credit issue will be corrected.
I have changed the settings homogeneous app version:
https://boinc.berkeley.edu/trac/wiki/HomogeneousAppVersion

You can test if now 64-bit applications will always come to 64-bit host :)

This happens on the iThena.Measurements project with the OONI application, I get both 32 and 64 bit apps.
I didn't worry about it as the 32 bit apps were faster than the 64 bit apps.

Somewhat limiting....

>>> This project doesn't support computers of type windows_x86_64


But it does support Linux running in a VM on a windows_x86_64 machine.....

There are easy to follow visual guides on how to run Linux tasks in Windows here if anyone needs

Have you already looked at 'Applications'?


Platform
Linux running on an Intel x86-compatible CPU
Linux running on an AMD x86_64 or Intel EM64T CPU

So: No, you can't receive work yet under Windows 11. You can install Linux using e.g. virtualbox and try it that way.

Agreed. It seems that these tasks have a very wide range of run times depending on the computer, and your estimate and max run time limit are too low.



Also, these tasks are actually using more than one CPU thread per task. On the E5-1650 with 6 cores/12 threads I had to reduce the number of running tasks down to 8 before the total CPU usage dropped below 100%. On the 3900X with 12 cores/24 threads, I had to drop it down to 18 running tasks to get the total CPU usage below 100%.

If the tasks were actually just using one CPU thread each, the totals would have dropped below 100% at 11 tasks on the E5-1650 and 23 tasks on the 3900X...

This might explain the higher run times than the original estimate as well. For those of us who usually run a number of tasks equal to the number of CPU threads, the tasks aren't getting the amount of CPU time that they want.


Pardon my ignorance but how do you reduce the number of running Tasks?
