i know you said they had issues with that server. do you know what issues specifically?

I only know what happened on that particular day. The card had arrived in a plain brown carton - enterprise version - none of the fancy packaging or silly fripperies you get in the retail market. Like manuals or accessory cables.

When we got back to the lab, Eric couldn't see the new drive at all. Quick online search for a user manual, and it turned out the card needed a supplementary power cable - which we hadn't fitted. At that point, the trail goes cold, as far as I'm concerned.

I'd say it's pretty likely that the server doesn't even support PCIe bifurcation. That is likely to be the main issue with that 4x m.2 PCIe card even if Eric ever gets the power cable he needs. you need more modern hardware for that thing to work. that card, takes 4x m.2 drives, which each have 4 PCIe lanes, and splits them amongst the x16 slot.

through cross referencing pictures and features I can see in your pics, I'm 99% certain that the motherboard in muarae2 is the Supermicro H8DGU-F. this is a very old AMD Opteron board.

This means that either it is not a true twin of muarae1, or the SSP specs for muarae1 are wrong or out of date. muarae1 (and 4) is listed as a dual hex-core 3.07GHz Xeon. the only chip fitting that description that I can find is the Intel Xeon Xeon X5675, which is another old Intel Xeon, socket 1366 with tri-channel DDR3 memory. very very different hardware than your picture shows.

what tipped me off to this discrepancy was seeing the single screw holding down the CPU heatsink. I knew no Intel CPUs used that kind of mounting.

Seti@Home classic workunits: 29,492 CPU time: 134,419 hours

some further digging looks like the card Eric picked up is either this or a clone of this one: RIIPTOP Quad M.2 NVMe SSD PCIe x16 Adapter, ASM2824

so this particular card *may* end up working, since it employs a PCIe switch connecting your 4x M.2 drives to a single PCIe x8 link. hard to say how such an old board will react to such a device though. sometimes combinations like this just don't work for unknown reasons. if it does work, you'll be limited to PCIe 2.0 speeds though since the motherboard in muarae2 can't do PCIe 3.0, effectively halving the total bandwidth.

Good sleuthing! Thanks and thanks to Richard.

But hey! That's still a useful speedup.

I've done far too much adding disks and bits to expand old servers myself, too often far beyond their original design and spec. The thing is... It really is amazing what you can get away with when using Linux systems!


There does look to be a LOT of disks in there...

Cue the s@h obelisk: "My God, it's full of disks"...


Keep searchin'!

Big thanks for all the photos! Hard to believe my first account (too bad I can't find it) was on all that first generation equipment. Nice to see the progression of the servers over the decades.

Here's hoping to another chance down the road if available!

OK, did some sleuthing of my own. Matt tells at least some of the story in his Technical News stories.

Message 1382796 (19 Jun 2013): Server-news-wise, we did acquire another donated box - a 3U monster that actually contains four motherboards, each with 2 hexa-core Xeon CPUs and 72GB of memory, and 3 SATA drives. Despite being in one box, they are four distinct machines: muarae1, muarae2, muarae3, and muarae4.

Message 1649365 (5 Mar 2015): One of our servers (the four-headed monster that is muarae{1,2,3,4}) developed a weird power issue - muarae2 seems completely dead. Fair enough, but when you try to power cycle it for some reason muarae4 power cycles as well.

Message 1788204 (17 May 2016): our web server muarae1 ... went bonkers around the start of the year. Well, we finally got a new muarae1 so centurion is back to being centurion - a dedicated splitter, a storage server, and potentially a science database clone and analysis machine. We also got a muarae2 server which is a back up (and eventual replacement) for the seti.berkeley.edu web server.

My 'twin' remark was a distant memory (without checking) that all four muarae servers arrived together. I'd not registered stages 2 and 3 in the saga. I don't think the server descriptions on the SSP have, either.

but it seems to have been dropped like a hot potato :/

I want to switch to something, but would like to keep looking for ET's.
Thx all!

There aren't any others looking for ET's :(

Einstein@Home is looking for pulsars and assorted gravity waves only its not looking for intelligent signals too like Astro Pulse is/was.

There are a number of biology/life/medicine projects out there.

But nothing that is looking for ET.

I would be glad to be wrong. Let us know if you find one!!!!!

After 20 years processing, this is a sad occasion. Seti has been part of my family for all of that time.
It is so sad to see it it go .... and just upgraded my PC too !!!
Farewell dear friend .. hopefully back in a different form ..

Hey Richard, thanks for the pics! Brings back good memories of my trip down there. Just got back into town, so this afternoon I'll have to take a dive into the forum here and see exactly what happened with our beloved project. I get the general gist of it, but would like to get more details if they are around. And Eric, if you see this, thanks again for the lemons, they were excellent!

Al,
I would leave at least one system idling on S@H. Just in case.

If you want to keep your cpus VERY busy you can try some Coronavid19 research at Rosetta@Home. Need more available HDD space in the BOINC settings and as much ram in the Settings as possible. Default is 8 hour tasks on any sized computer.

Hey Tom, I've, over the years, been temped by other projects during some of the periods of 'the troubles', but if you take a look at my sig, the only one I've ever participated in is SETI. Almost half a billion credits, and yet _still_ waiting on my toaster... ;-)

I think another person up thread mentioned it as well, but I am really only interested in participating in SETI kind of work, as it's something I believe in, and I believe he posted the question if there was another project that was basically doing nearly identical work, and no once ever replied with one that was about the same as this one.

So, you're probably right, I'll keep one rig up and idling, and who knows, maybe a few tasks will be tossed out now and again, or maybe (hopefully) it will be up and running before we know it. One can only dream at this point, right?

You are right. There is literally no other (yet) BOINC-like project that is looking for ET. There are "several" astronomy/space projects and "several" biology projects out there but no "astrobiology" so to speak.

Several people I know who had "Farms" smaller than yours have dropped down to one or two machines. The rationale was always the same. Nothing like S@H and OMG the electrical bill is coming due :)

I got a 16 gpu rig up and stumbling during the last week of S@H but I already knew I couldn't sustain the electric bill. So it has been "resting" while I sell the surplus of gtx 1060/gtx 1070/gtx 1070ti's that topped it out. I am still sitting on the p100-102's right now (apparently slightly cutback mining gtx 1080ti's).

ps. I have posted a possible "DIY" Seti Toaster idea but it depends on you successfully insulating the S@H image/decal so the things don't go up in smoke when you actually use the toaster. You get a Seti Anniversary T-Shirt and....

I finished the last remaining workunits. Due I am really only interested on doing SETI I left BOINC manager running idle in the background.

In only the first three months of this special year 2020 we got a lot of unexpected surprises, who knows what more surprises lay ahead! perhaps SETI@home resumes again….. perhaps the analysis of data collected shows ET calling….

Yes, a disappointment in some ways, but the knowledge that there's a lot of 'crunching' and 'hmmmms' to come out of it all is going to be rewarding anyway. Hard to believe I first logged on almost 21 years ago! Wish I could say it was all contiguous, but .... at least I'm here at the end! Cheers, all.

Does anyone know if there will be a new type of Seti@home in the future??? After 20+ years of donating my time and computing, I'd hate to think this is it.....

At least not in the near future. First of all, they will develop their backend pipeline, test it and gradually apply it to the mountain of detections from 20 years in order to evaluate and score them. The end of data analysis by us, the thousands of volunteers, is the bitter and sad news that we have to accept so that this project can be successfully completed by publishing a detailed, meaningful result.

As SETI news announced on March 2: (see first message of this thread)

We hope that other UC Berkeley astronomers will find uses for the huge computing capabilities of SETI@home for SETI or related areas like cosmology and pulsar research. If this happens, SETI@home will start distributing work again. We'll keep you posted about this.

First put s@h on a work PC when i moved to SanJose in 2000, created this acct when I moved to Boston in 2010.
Just pushed out my last two WU today.
Going to miss the screen saver... 8^)
Time to join some other projects...
