Bad Work Unit for All a7 Cores

On one machine, all my a7 work fails immediately:

Post by JimboPalmer »

a7 does not run in a virtual machine, (a4 does) are you virtualized?

In the advanced client have you tried 20 CPUs? -nt (number of threads) keeps counting down, but then gets confused by multiple -nt parameters

(i suspect a line where it goes from 23 to 22 was omitted)
It goes down from 22 to avoid a multiple of a large prime, 11
Sadly 21 is also a multiple of a large prime, 7
20 would have 5 as the largest prime, 5 is often OK.
if not, the number of CPUs as 16 is a sure thing.
if you wanted you could make 2 CPU slots one 16 and one 6, neither would have large primes.

In the a4 setup you can see it drop from 23 CPUs to 20, which works.

As to why you have 23 CPUs, I suspect one of two scenarios, one is that you have Folding on medium (number of CPUs minus one) or two, you have a GPU you did not tell us about. If it is the first you could change to Full which is 24 CPUs, which has no large prime factors. If you have a GPU, turning the CPU client down to 20 CPUs is best.

I have one GPU folding, which may be when the problem started. Using 24 cores was not a problem. I am using the beta client, would this not automatically adjust the remaining cores to a stable configuration? If not, what do I need to do to fix the problem? Is it a setting under "Configuration"?
Thanks!

I found the setting. Will force it to 20 cores for CPU, presumably setting to 22 will not work because 11 is a large prime number. Thanks.

If you worry about the 3 idle cores, you can make a second CPU slot with CPUS = 3, but it won't add much.

Glad you got it fixed!

Do you pass arguments manually using extra-core-args in advanced slot settings ?

There is a known issue with Core_A7, https://github.com/FoldingAtHome/fah-issues/issues/1179.
