All Cpu's are taking a break for a moment........maybe a week or two.


An idea for future BOINC events would be practicing Bunkering...say every two months or so just so that some of us noobies can work out the kinks and be ready for the next Penthalon.

That would be good to have some VMs setup with Boinc ready to start up, grab tasks, turn off networking and crunch. I tried on pogs but it made the PC and VM so slow that boinc mgr wouldn't even open. Def need to try that a few times.

That is something that we could work on at the monthly BGB events.

Bunkering and Linux on USB sounds like the way to go. Have several USB OS's primed and ready. Timing would be critical.

I just love messing with hardware. Peeps in the Guard unit have learn to not get me on the subject. tongue.gif I usually will talk their ear off, but when ever someone has a question on hardware. I am the one they come to.

Basically I probably being doing little projects with a Pi 3, but be neat in between to do some BOINCing on it. First project is making that auto water controller I read in a Linux magazine. I so want to fool around with that since I am working on my garden. Huh....I wonder if there a way to smack PH and water level readers on one.

Especially since I do plan to build an aquaponics garden later on this year or next.

I definitely have to agree, especially given just how inexpensive Raspberry Pi 3's are, AND they have wifi built in! The more I look into things (and find more links to cluster towers that are inexpensive but decent looking on eBay, as well as easier power solutions for several Pi's) the more tempting it is to do. I'll tone back on the ODroid idea though, because once you add in the eMMC memory (which is significantly faster than SD, although I don't know how much that would actually affect BOINC usage) it quickly brings the cost of those devices to a much higher price point (XU4 is $188 CAD w/32GB Android eMMC, C2's are $150 CAD w/16GB Android eMMC (or $166 CAD w/32GB for a comparison that's closer to equal between the two))... Or, in short, while the Odroids are more powerful, I can get a decent handful of Pi 3's for the price of one Odroid, although there isn't as much support with various projects.

Still tempting to get at least five of each over time though, especially since the Odroids could do some serious work with WCG, and the Pi 3's would do a good job at Einstein..... ....Guess it will all depend on how certain things pan out over the next year, but it's definitely a neat idea to contemplate, especially since I was looking at the idea of dual Xeon servers as well so I might as well try and compare them.

Well that was fun! Got to really give me 6800K a workout, and I can't think of any better stress test than running at 100% for a week straight. tongue.gif

Although now I'm immensely jealous of magic8192's beast machines. It almost makes me want a Xeon system of my own.

Can get a nice 2P setup for just under $500 USD over at Natex... Such would at least provide a small chunk of what Magic has ^_^

Thats why I bought several small SSDs and USB 3.0 drives with the 2P system.

How much can a Pi 3 actually output? And how many would be needed to get to i7 performance? There's got to be a cost penalty to get everything in that form factor. I have one that I think is the Pi 2 that I never really setup to do anything. The whole, complete package I think was $70 with memory card, wifi and charger.

I've read that the Pi 3 can do ((EDIT 19 Jun 2016 @ 20:53 MST: Totally forgot I had started a sentence, then I apparently forgot to finish it. Not quite certain where I was going with this, but I suspect it was something along the lines of "seems to be able to be competitive in a PPD/watt manner... Or... Something. end edit))

Here's someone running an ODroid C2, which is a quad core A53(ARMv8) that runs at 2GHz: https://einstein.phys.uwm.edu/results.php?hostid=12260646 . Apparently it's running an optimized version. As for Raspberry Pi, this is an unknown (Bikeman didn't really say what it was): https://einstein.phys.uwm.edu/results.php?hostid=12256143 ....

Using that info from that particular computer's bench runs, my STOCK CLOCKED i7-4770k (with 16GB of DDR3-2400 CL10, running on Windows 7 Home Premium 64 Bit) is 5.83x more powerful for measured floating point speed, and 6.38x more powerful for measured integer speed. Factoring in that there's only four cores in an RPi3, one would need 12 Raspberry Pi's to match my processor for floating point speed, and 13 of them to match the integer speed. Or, in short, you could technically come ahead if one were to go with pricier (and new) gear for the 4770k, but even then it's still only at most $500 USD to get a really good 4770k setup going, even cheaper if you hunt around for deals. Twelve Raspberry Pi's would win on power consumption though, as they'd only use half the amount of power (or potentially even less, if you overclocked the 4770k), but you're also having to deal with the possibility of SD cards corrupting or even dying (a common complain for those running clusters of them).

Even comparing against the ODroid C2, a 4770k outweighs it by 3.34x for measured floating point speed, but loses out by a factor of 2.17x for measured integer speed. What do those stats mean? I have no idea. *laughs nervously* But one does have to realize that when you go with the more "reliable" options for the ODroid (emmC storage), the costs can jump fairly quickly ($166 CAD per unit is what I'd pay from the Canadian distributor, if I remember correctly. Never did check US distributor pricing, or costs of purchasing directly), and once again factoring in buying new you would only be able to get 3-4 of the C2's before matching the price of a 4770k.

However, for the thought of having something to tinker with, it is an idea I definitely like. 2P Xeon E5-2670 setup alongside a decent handful of Raspberry Pi 3's (say five or even ten if I'm feeling nuts), five or so ODroid C2's, and another five or so ODroid XU4's would wind up being costly in the end, but at the same time... It would definitely sate my desire to tinker with a wide variety of things, and on top of all that they're just so neat of a device.


And I just found out about the Jaguar One... Interesting little unit.


EDIT (19 Jun, 2016 @ 12:31 MST): Or I could go with the much cheaper option that isn't quite as techy and put two systems into a Phanteks Enthoo Mini XL DS and kill off a number of birds with one chassis/stone - mITX setup (always wanted one), dedicated BOINC cruncher (always wanted one, even if it's "just" a 6700k), AND to top it all off I can pretty much guarantee that once you stuff it full of things it will look rather lovely and full, especially with SLI in the one rig, and a single card in the other..... But I still also like the idea of having a wide variety of devices to muck around with, as well as potentially a big powerful server of doom.
