Well I have set the PiVE loose. All 4 Pi3s in the PiVE are running 4 concurrent WUS on Ubuntu Mate and utilizing Mate's BOINC.
I had to change my assembly logic on how to connect/orient the cylinders to the fan plates on the front. Initially I thought the USB power connectors should go to the inside but trying to get them into the port and then into the Piz connector proved most annoying (impossible) so I disassembled the cylinders and oriented them such that the USB ports were to the outside. Much easier. I could still route the USB cables to the inside and out the rear. Nothing proves a design like "doing it". Never glue.
Here is a very short video of the PiVE online with all cells in violation of high temp limits. Done intentionally so I can force email to report current temps every 15 minutes.
Now that the Pi3 is happily crunching Arecibo work units I can catch up around here.
@Bikeman
Very interesting projects you have there. The meteor one is of particular interest to me and I may give that one a try. I have a SDR but could never pick up anything on it no mater the antenna nor the PC i tried it on. They are cheap may get another and try again.
I run Kodi on my Nvidia Shield for music and internet radio. Love it.
@robl
Loving the PiVE. Looks almost sinister, like in a sci-fi space flic where the AI won't let you back in....
I wondered how you managed all the cables coming out the sides.
I put the Pi3 on the top deck of my mini-stack and put the small fan that came with it on. Crunching 4 work units with 23c ambient with fan blowing down on it vcgencmd reports 58c after 4 minutes of crunching.
I like these because everything being powered over USB is a requirement for my clusters (this includes the Pis, the Network Switch, and Fans. I am using a 96watt 10 Port USB Power Supply that I picked up from Micro Center. Several 60ish watt USB Power Supplies are available on Amazon from Anker and Sabrent. I am using Trend Net 8 port 10/100 "GreenNet" switches which run on 5V, and I was able to get USB to Type M connector cables from Amazon as well (though not short ones).
I have 7 Pi 3s sitting in their boxes on my desk, waiting on me to get the time to assemble my Pi 3 stack. Right now, my one Pi 3 running 4 E@H WUs is keeping 1.2Ghz speed, and staying under 50C w/ fan and short Al heatsink in an open area on my desk (no enclosure of any kind). I hope to get the cluster built up soon.
I have looked at those fans. Now I am looking closer. Thank you for pointing them out. What you describe for your cluster is what I am toying with as what I want to do. If you do not mind posting some pics would be nice. :-) I like seeing how people put things together. I lack creativity or imagination so I use what others do to get my ideas.
If there are no rules against having more than one account I may put my Pis under another account and join your team. I have been with my current team a long time and have several friends there. A Pi centered team has some appeal.
IBMs World Community Grid started in 2004. Before that I ran 5 Pentium Pro in a FreeBSD cluster doing Distributed.net. I used a dual pentium 166 also running FreeBSD as the control node and Distributed.net proxy server. It was a lot of fun. I see the Pi 3 as a way to get back to something similar at reduced cost to set up, greatly reduced cost to run and not requiring an entire small bedroom to house and deal with heat. I have to shut down all my GPUs during the summer. With a Pi cluster I can still contribute.
Yes, life is good with Raspberry Pi in your life. :-)
I'm getting a Pi3 to crunch E@H. There is a lot of good information in this MB but it can be a little hard to follow. It sounds like Ubuntu Mate will allow me to run the GW and GRP applications. Is that correct? It also sounds like heat sinks and/or a fan are a must have running applications on every core.
I've been running a Pi2 crunching E@H for 2 years. The thing is rock solid and I may have accessed it twice in those 2 years. Consequently my knowledge is out of date.
^^^ works like a charm to fix the RPi3 'connectivity(?)' issue.
Poppageek, what types of speeds are you getting for your runs?
For the Arecibo's, I'm getting...
Run time 11 hours 1 min 51 sec
CPU time 10 hours 43 min 11 sec
I'll tinker with some of the overclocking this week to see how high I can go. I tried a 1300 and it eventually froze up while running these Einstein projects on BOINC.
KF7IJZ, i'd be down to join that team too but i have some non-pis attached to my account....is Poopa right about not being able to set up multiple accounts? if not, i'll start a rasPi exclusive account this afternoon and join. i love the pi team idea!

Thank you Richard. That revealed that it was the old SSL problems with certs. A quick search and this got the project attached:

I unlugged the fan and it temps climed slowly to 68c and then rather quickly to 74c. I plugged it back in at 75c.
The fan is quiet and there is no noticeable vibration. It will do until I find a better solution for the Pi3.
Cheers!

I have my Pis open to the air with these fans, stacked, blowing over the heat sinks: http://www.amazon.com/AC-Infinity-MULTIFAN-Receiver-Playstation/dp/B00IJ2J2K0/ref=sr_1_1?ie=UTF8&qid=1459775616&sr=8-1&keywords=ac+infinity
