Hi Sergei and the community,

​With the launch of Intel’s Panther Lake (Core Ultra Series 3) architecture on the 18A node, I’m planning to deploy a high-TDP (80W) Mini PC as a dedicated "Green Cruncher" for Amicable Numbers.

​The new Xe3 architecture (derived from Battlemage) looks like a perfect fit for this project.

It features hardware-native FP64 support and a significant increase in vector engine width compared to the older Xe-LP and Xe2 units.

Given the efficiency of the 18A process, these iGPUs should provide excellent throughput-per-watt for the 10^{21} search.

​I am aware that Part 3 of the 10^{21} search is memory-intensive, requiring ~2.5GB to 2.7GB of VRAM per GPU task.

To ensure stability, I'll be running this unit with 64GB of DDR5-9600 RAM, allowing the iGPU to comfortably allocate the necessary system memory without bottlenecking the OS or other background tasks.

​Intel’s official retail launch is January 27th, and I expect my unit to arrive in Denmark in early February.

Once it's set up, I can provide the specific PCI ID and clinfo logs to help with whitelisting the new Arc B390 iGPU for OpenCL tasks.

​Is there anything specific the project needs to see in a test run to enable the "Intel GPU" plan for this new architecture?

I’m happy to run the Amicable_OpenCL_v_3_06.exe standalone benchmark as soon as the hardware arrives to verify stability.

Unfortunately the project is at end-of-life stage. It will be finished in early March, so there is no point to do more development work for it now. But that hardware you'll be getting looks really interesting though, I'm sure it will be very competitive on any BOINC project!

Hi Sergei,

​Thank you for the update!

It's great to hear that the project is so close to reaching its final goal.

I completely understand that with a March finish date, it doesn't make sense to start any new development work for the upcoming Panther Lake hardware.

​It has been a pleasure contributing to the project, and I look forward to seeing the search wrap up successfully over the next couple of months.

I'll take your advice and keep an eye on other BOINC projects once my new setup arrives!

​Best of luck with the final stretch.
