By the way, and returning to the original topic of this thread to finish with some conclusion:
Current New Version of ACEMD 2.18 came back to the same wrapper v7.7.26016 previously used and working with old app v2.12
When I was trying to debug, it coincided that I had stopped one of my hosts while v2.12 was the active app version.
I recovered the wrapper packed with that app version, file wrapper_26198_x86_64-pc-linux-gnu
I renamed it the same than the failing wrapper included with app v2.17, wrapper_26014_x86_64-pc-linux-gnu
Then, I copied it to folder /var/lib/boinc-client/projects/www.gpugrid.net in replacement of existing wrapper file.
After that, I was able to finish v2.17 task 1_4-CRYPTICSCOUT_pocket_discovery_9a871de0_3995_4230_8b91_6874b82272c0-1-2-RND6341_2, which, at last, partially ran at device other than 0: device 2
I kept screenshot of this:



Based on this test, I'm pretty sure that the problem in New Version of ACEMD 2.17 app was due to wrapper version 7.5.26014 packed with it.

Finally, this problem was corrected by the deployment of New Version of ACEMD 2.18 on Sep 14 2021 | 11:44:39 UTC
