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.

Grant, I like. Good shade-tree engineering.

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.

Both the Einstein GW tasks along with the GPUGrid tasks are sensitive to memory bandwidth.

The 1650 only has 128 bit memory width versus the 192 bit memory width on the 1060.

So even though the 1650 has more memory than the 3GB 1060, the 1060 still outclasses the 1650 on these applications.

Bernd at Einstein said that they
He also said they are developing a new Radio Pulsar search to make use of the high powered AMD and Nvidia cards.

Interesting information. I wonder what is classed as high-end

He didn't say exactly "high-end" This is what he said.

FGRPB1G will eventually run out of work as well, but we are working on a new Radio-Pulsar search that will run on the larger AMD and NVidia GPUs then


In this context it could mean newer cards with greater compute capability and likely more memory. So possibly not able to run on ten year old gpus anymore.

I'm not worrying about that as this issue is still far off in the future.

Bernd at Einstein said that they recently received a ton of new Arecibo data.

He also stated that the FGRP5 search has exhausted any new "promising targets" = scientifically relevant "work" than the current one"

That is the reason they have deprecated search resources for the FGRP5 apps and are now concentrating on the new Arecibo BRP4 beams.

He also said they are developing a new Radio Pulsar search to make use of the high powered AMD and Nvidia cards.

So we might see a return of the old BRP4G application or a newer, updated version for this new data eventually.

I haven't been able to snag much of any. Only 9 tasks on one host, nothing on the others. Just endless nothing to send request reports.

Curious to know where people putting their processing power in regards to Covid research? While there is no WCG. I am aware of Folding at Home (Non-boinc can use GPU & CPU) and sidock (Boinc currently CPU only) I am also aware there is a non-boinc version as well

I would assume the approximate conjugate project would be SiDock.

I continue on with Einstein predominately for gpus and for Universe for cpus.
Our GPUUG team continues to put as much effort into improving the science apps at Einstein as we did with Seti.
Making great progress.
First iteration for the Separation app was at the same equivalent stage as the Lunatics apps adopted by Seti.
Einstein admins adopted those quickly to launch the 1.28 version.
Current iteration is at the Seti "special sauce" app stage. Basically a rewrite of the original application I believe based on the stderr.txt output.
Milkyway's boards are very infrequently used. Strangely quiet compared to most projects boards. No idea why.

New AMD Milan-X cpus are up for ordering now at ShopBLT
https://www.shopblt.com/search/s_all=EPYC&s_max=25&s_lastpos=4688760&order_id=219337371
But a big 34% increase in price for the 7473X 24C over my existing 7443P 24C cpu. Think I will skip it and wait for Zen 4.

Probably a permissions issue.
Why don't you start the client and the Manager in terminals so you can see the output of both for better troubleshooting information.

Still plugging away in BOINC.

Oh, I get it. You have installed a nvme drive in a USB carrier. I thought it was installed in a motherboard M.2 slot.
Have you looked in the USB hosted nvme drive via Disks to see if it has a FAT UEFI partition on it?
You may be having conflicts with two UEFI partitions hosting two different grub configs.
You should have only one in play.
Whatever Mint installation is your normal default one probably should support the grub file that boots both versions of Mint.
If you can get both Mint versions visible to your default OS, I would run os-prober and see if you can get it to write a correct grub file for both Mint entries.
Barring getting that to work, I would do some editing in the default /boot/grub/grub.cfg file to add the second Mint version. You could just copy the block for the normal Mint OS entry behind the original one and just change the UUID entry for the second Mint version.
Then go into your /etc/default/grub file and change the GRUB_DEFAULT= line to point at the preferred Mint OS entry. Remember to do a update-grub afterwards.

I think it is a bit much to have to open the computer and pull out the nvme drive from the slot every time you want to boot the other Mint version.

The drive names shouldn't be changing for the nvme drives. You mention a USB drive though and I am confused. USB drive names will change if you plug them into a different port.

The drive names shouldn't be used for the grub entry or the fstab entries. That is why I suggested you define a drive by its UUID. The UUID will not change. It is like a fingerprint identifying the drive no matter where it is installed.

You didn't by chance clone the second nvme drive from the 1st did you. That would make both drives have the same UUID and I can see why you are having issues. That would be a big no-no.
