There used to be the gpu Separation tasks at Milkyway. But that sub-project finished up over a year ago.

The AIO was made by TBAR. You can just download the .deb files from Boinc and unpack the binaries from them in /Downloads and then copy them over into your AIO directory.

The deb files are located here. Take your pick of versions. Either the 7.24 you were looking for or even the 8.0 Alpha. The alpha is available from Boinc versions web page but of course that is the standard installation type and install directories and not the AIO directory location.

Virgin Galactic is selling tickets to well-heeled tourists with the analogy of buying a ticket to the ferris wheel ride at your local fair.

It's just entertainment.

Looking forward later this year to the resurgence of AMD HEDT platform with Zen 4 "Siena" cpus.

AMD 8000 processors with 32c/64t or 64c/128t configurations using the Zen 4c core.

Packages and sockets will have the same footprint as SP3 sockets with a slightly higher pin count per socket. Socket is SP6/TR6.

Cpus will consist of 4 CCX dies and an I/O die with the CCX's containing 16 Zen 4c cores. L3 caches will be half of Zen 4 cores. Same 96 PCIE Gen5 lanes as Zen 4.

Speculation that the internal microcode in the Zen 4 die already has optimized pathways that take into account the security mitigations.

Or that the software developers have optimized their code pathways to choose the fastest route with the standard security mitigations in place.

Phoronix posted their in-depth benchmarks of the new Ryzen 9 7950X and 7900X cpus on embargo lift today.

https://www.phoronix.com/review/amd-ryzen-7900x-7950x-linux

Great performance uplift over Zen3 and Intel AlderLake cpus. Wins 74% of over 300 benchmarks.

Fanastic AVX-512 results with no clock speed or power penalties over AVX2.

I think I can count on one hand the number of users that have been successfull getting the ROCm OpenCL components to successfully crunch BOINC gpu tasks.

OTOH, the standard AMD drivers seem to work on the older cards as long as you install the legacy OpenCL components on the install command line statement.

ROCm just seems to constantly be a "work in progress" with off-again, on-again success with BOINC, the driver package and the kernel level compatibility.

Well the production at 2x is still better than 1X. As long as the task elapsed time/2 is less than the 1X time, you get more production.

You just need more cards for winter heating. I will have no issues keeping the house warm during the winter using 13 cards.

Just watched the AMD AM5 product release and am very pleasantly surprised at the MSRP pricing of the stack.

Can't complain about the Ryzen 9 7950X retail MSRP pricing of $699.

That is $100 less than the launch price of the Ryzen 9 5950X. Cheaper and better performance all in one generational uplift.

Assume the aggressive pricing of Alder Lake by Intel had something to do with the pricing. Gotta love manufacturer competition for benefiting the consumer.

Actually if you stick to the base DDR5 spec of 4800-CL40, the modules are not that much more expensive than DDR4.

It's when you push for the higher speeds and lower latencies do the modules go stratospheric in cost.

I wondered why there was no stock of the Asrock Rack ROMED8-2T anywhere when I looked last month.

Now I see that they have released an updated version of the board called a ROMED8-2T/BCM where they subsituted a Broadcom 10Gbe LAN chip for the prior Intel 550-AT 10Gbe chip.

Looks indentical otherwise physically and spec-wise.

[Edit]
Not quite the same, I just noticed they dropped the USB-C connector on the I/O panel.

Yes, agree that the lack of an additional PCIE aux power connector input is surprising given the ability to use all seven slots for high power gpus.

I do see that they changed the board ATX12V power inputs from an 8 + 4 pin to a 8 +8 pin to allow for those higher cpu clocks on WRX80 Threadrippers compared to the ROMED8-2T boards.

Looking forward to Dr. Lisa Su's keynote speech at Computex 2022 on May 23rd.

Expect to see the announcement of the new Zen 4 Raphael processors.

Board partners expected to announce the new platform a while later in the month.

. . That all looks pretty but there seems some confusion. The page is labelled Universe@home and at least one graph is too, but one graph is labelled einstein@home. Can I presume this is because it is a work in progress?

Stephen

No they are all the graphs for Universe. The part that says Einstein is the toggle link to switch all the graphs to showing Einstein.

First AMD Genoa motherboard and SP5 socket image with 12 DDR5 slots.
https://forums.servethehome.com/index.php?attachments/lga6096-png.20966/
See the socket attachments of SP5 for the cooling solution has changed to 6 threaded posts instead of 4 threaded sockets of SP3.
Expected I guess to be able to pull the cpu evenly down to mate with LGA6096 pins.
