[PrimeGrid] GFN-15 upgrade to Genefer22

[BOINC_News]

We've updated the GFN-15 apps to the 2022 version of Genefer. With this upgrade, we are adding support for CPU apps (including multi-threading), native Apple M1 apps (both CPU and GPU), and discreet Intel ARC GPUs. For more information, or for discussions, please click here.

The "click here" link reveals the secret how this was made possible with respect to PrimeGrid's server capacity:

Note that we are NOT yet doing fast DC on GFN-15,

Translation: Different from the bigger GFN subprojects, GFN-15 is not using the combination of normal "main tasks" and small cryptographic verification tasks (small from the perspective of the clients, but heavy on the server). Instead, two, or when necessary more, classic "main tasks" per workunit are distributed, like before the application upgrade. What remains is that the upgraded application supports more hardware.

Also from the link: OCLcudaGFN15 is temporarily reverted to the older genefer application due to an issue with validation.
