Octane with 2x R14k 600MHz does 2x 0.28 khash/s.

At least that's faster than the Raspberry... :roll:

So I let the Octane mining for around 3 hours: earned one share :)

I'm seeing .11 Kh/s out of my Octane (250MHz R10K).

Doesn't want to compile for me with MIPSpro (-pthreads not supported or something like that)

I've only got GCC installed on my SGI O2. If someone wants to provide ssh access to an IRIX box with MIPSpro installed I'm willing to compile an optimized version of cpuminer.

assuming that it would go through with mipspro at all ... thinking of bitcoind which is serious bloatware with some silly flaws in the build system

Yes, assuming it is possible. One can only try their best when fighting with GCCisms in code.

I should be able to help with this. PM me and I can send you details.

Gave it a run on my other Octane board (the other system wasn't booting, so I swapped the motherboards) (system is 2x 175MHz R10K, 1.5GB RAM). Result is 2x.08KH/s. I wish I still had the 2x 300MHz Octane that I was using in college in the LUG....I wonder if that is still there....

Lol, I can't believe so many people got into this! I built it back in Dec and left it running on my O2 600Mhz-- 0.21Kh, btw.

Sorry to disappoint you Geoman, a Fuel/900 gives about 0.4, though as I type this it's wavering
between 0.33 and 0.36 because of Firefox 3.0.19 and other stuff running at the same time.

Hmm, I might shut FF down, see what it does...

EDIT: without FF running, it gives 0.41.

And what about putting one of those USB-based asicminers into Fuel's USB port for bitcoin mining?
The have got an Uart chip (internally they connect via serial port) on them and run inter Linux, too...

But in the end this all makes no sense at all :-) Raspberry pi draws much less energy than a Fuel and don't make a sound.

Bitcoin mining is a complete and utter waste of time for a home user. It ceased being financially viable many months ago,
as the power costs now far exceed the mining returns, all as a result of ASIC/FPGA systems, etc. Rising energy prices
have made it worse, as have rising component prices for PC builds.

Litecoin uses a different algorithm for which there aren't any ASIC solutions as yet, so it's still viable atm, which has
resulted in a sharp increase in prices for AMD GPUs such as the 280X/290X/etc. What launched as good price/performance
alternatives to the 780/780Ti, especially with aftermarket coolers, are now far too expensive, and also top-end PSUs have
either gone way up in price, or they're impossible to find.

As for running minerd on a Fuel, I have my Fuel turned on a lot of the time, so it may as well be doing something useful,
good for a laugh. :)

Here too: My PC is running all the time, so the Radeon HD 7750 is doing around 100 khash/s (around 150 possible, but then the GUI gets sluggish), and I got myself an Antminer-U2 USB-Stick, which is doing around 1.6 Gh/s.

Of course this is more fun than anything else. I had the 7750 installed 1 year ago or so - so for Litecoin-mining I have no extra expense (and for electricity: my PC is nearly alwas on with or without mining), for the Antminer I paid 40 EUR just for the sake of participating. Draws around 2-5 Watts from USB. (of course directly buying BTC would be the sensible thing to do)

But who knows: If cryptocurrencies become really established in the future, we are now pioneers :D and in 10 - 20 years we can say "I was part of the beginning".

Curiosity was burning a mental hole, so I tried out my 5GHz 2700K, which gives an average of 67.28 khash/s for CPU-mining. :D
