Aww it was cool. You were the top user for a day, hehe.
Just please be kind and not leave 22,500 task in your caches.

[edit] Detaching each rig from the project will clear them if you don't want to finish crunching them. ;-)

Speculation is pointless, I have a good reason to do this and SETI@Home serves the purpose. I may do more, as this is only a few racks in one row of several in my data center. It's only temporary, will end when it ends. Enjoy the fireworks.

I will say that I am not interested in competing against anyone. I just happen to like SETI@Home, even though I know the odds of it finding what it is looking for are infinitesimal.

Oh don't get me wrong I'm in this for science and am more than happy you've dedicated your machines to the search.

I'm just a little envious of your data center compared to my small farm. Unfortunately I'm constrained by available space, power and finances.


...and just like that, I have turned it off. Oh, well. It was fun while it lasted. But like Arnold said, "I'll be back." :)

Machines come and go. The search must go on...

I'm one of those just coming back online here, built a new rig and figured why waste cpu time while i'm at work/sleeping when there's science to be done.

Its just a modest FX-6300, 1050 ti, 24Gb ram, but I do have plans for some sort of Ryzen by the end of year

If you are really interested in having that Gtx 1050 Ti really smoke (claims of 750 Ti running 329 Gflops) take a look at these. You need a NVidia gpu to make it work.

https://setiathome.berkeley.edu/forum_thread.php?id=81271

Or try the Lunatics Beta6 install under Windows for a faster than stock 1050 Ti and cpu processing.

It depends entirely on the specifications of the card. Certainly the card(s) are supposed to be cheaper for the same level of performance. If you are like me, a GPU with the same level of performance but a lower cost that I could add-on to an existing system, I would go for it. (Power Supply and MB slots being available).

If any of the systems you are currently running are desktop machines, you could add something like a GTX 1050 TI https://www.amazon.com/gp/offer-listing/B01MF7EQJZ/ref=dp_olp_all_mbc?ie=UTF8&condition=all and get a very large bump in Recent Average Credit for as little as $128 USD.

Well as almost everywhere you look it states that off the shelf GPU's are not recommended for Bitcoin mining, so if they are going to be aimed at the Bitcoin market they may well not be suitable for SETI@Home.

Bit coin miners use Application-specific integrated circuit (ASIC) miners and they are built for one task, mine bitcoins and do it faster and consume less power than standard GPU's, and as you don't use a GPU to mine bitcoins, you probably couldn't use an ASIC miner to crunch SETI.

It will be interesting to see, if the rumour is true, exactly what these cards can and cannot do.

It will be interesting to see if CUDA/OpenCL are implemented on these devices as doing so would make these devices useful for processing SETI & other similar applications. If these are not implemented, or the implementation is seriously compromised then they become of little use for SETI type processing.

Bitcoin is pro ASIC, but Ethereum the currency currently causing miners to get GPUs, if you haven't heard about the RX 400 and 500 series shortage, is because Ethereum, the algorithm is anti-ASIC, and using(favours) Radeon cards is the best value or the best ROI(Return on Investment). I think the return on investment is like 14 days for it being priced at US$350, and obviously it increases as the price of the card increases. The last figure for the RX 580, it was sold at a retail shop for US$900 and miners still bought them.
And that is why Nvidia wishes to market this..... system to miners
My understanding is that these cards will feature the GP106-100 chip, which is something similar to what is inside the GTX 1060 cards.

Radeons were the card of choice for early bitcoin mining till the development of appropriate ASICs and the increasing amount of processing required to mine them.
I expect this will be no different- for a specific purpose a specially designed dedicated device will almost always outperform a general purpose device. Once production ramps up, the cost of that dedicated device can fall to very low levels, relative to it's output.

Here is the algorithm that powers ethereum https://github.com/ethereum/wiki/blob/master/Dagger-Hashimoto.md
I have only read the first few paragraphs, but the algorithm is designed to be memory intensive, which is why ASICs don't work or have little benefit

More DRAM and larger buffers/caches on the ASIC.

Oooh here is what I found in the white paper:
https://github.com/ethereum/wiki/wiki/White-Paper#mining-centralization
The current intent at Ethereum is to use a mining algorithm where miners are required to fetch random data from the state, compute some randomly selected transactions from the last N blocks in the blockchain, and return the hash of the result. This has two important benefits. First, Ethereum contracts can include any kind of computation, so an Ethereum ASIC would essentially be an ASIC for general computation - ie. a better CPU. Second, mining requires access to the entire blockchain, forcing miners to store the entire blockchain and at least be capable of verifying every transaction. [...] one notably interesting feature of this algorithm is that it allows anyone to "poison the well", by introducing a large number of contracts into the blockchain specifically designed to stymie certain ASICs.

If they are able to stymie certain ASICs, then I expect it would be possible to stymie certain applications.

I haven't looked at the algorithm, ie code in close detail, but I think it randomly chooses an algorithm for each set of blocks, for example 10 blocks it could be some hashing function, another 10 blocks later it would be a different function, so the device has to switch quickly, as well as read blockchain transactions fast

My Huawei G700 runs tasks in about 200,000 - 300,000 seconds.


Those tasks sure take a long time, for me it usually takes about 60,000 seconds with the S4 mini.
