A simple guide explaining how to get Einstein running on the different PIs would be great.
I remember trying to get bionic working on my B+ was a mixture of following a number of posts and YouTube videos.
Since here were mention on BRP and bunch of other stuff to make the crunching faster, that only after tons trying did I work out it was for PI 2 and 3 and that it would not work on the B+.
Maybe keep your cache fairly low. I run my Pi3's with 0.25 days cache setting in BOINC. That should reduce the chance of getting one that later gets cancelled by the server.
We've had some disturbances in the clusters last night - several SD Card failures - I was able to replace one last night on a machine that hadn't phoned home since 9/22, should be ok now. The other is the Node 0 for the Pi 3 cluster, which could impact all other Pi 3s since it is the NAT/Gateway for their network. I will look in to rebuilding over the weekend. This event also makes me want to start looking in to network or USB booting and moving away from SD Cards all together.
I had to reimage 2 Pi's this week as well. They were returning work but were getting validate errors and that was running the stock app.
I was thinking it might be possible to have a single node in the cluster (in your case probably the gateway) using a HDD and the others having a share to it. I have an old powered external HDD that I could setup on one of the nodes but getting them to boot using the SD card and then point to the share for their root drive is the complicated part.
Unfortunately no GUI so gparted is out. I might experiment with one on the weekend and see if I can find a tutorial that only assumes CLI to get it across. Then there is the next step of trying to get the other Pi's to have their root dir on the shared disk.
By the way can you US (or European) guys get the Pi drive? They aren't available for sale down here in Australia for some reason. In the mean time I will use my old Maxtor OneTouch II (80Gb).
they are readily available here - my MicroCenter stocks them and the full Pi Drive kits. I hadn't thought to look at this just yet. I did pick up a compatible USB flash drive to try the boot from USB beta. I think it would be good to boot from a physical USB drive for the primary node and then try the experimental network boot for the rest in the cluster. My guess is that we'll see a Pi 4 next year that has these built in and production ready.

Couldn't wait for the weekend so did the first part tonight. It seems the OneTouchII won't work, gets an error when writing the partition table. Works fine with Win7 though. I ended up using a Seagate Expansion that I also had and got it using the HDD as root. I found a tutorial from 2013 on the Rpi forums that uses fdisk. The Seagate turned out to be even quicker than a Sandisk Cruzer Switch (USB thumb drive). I will put instructions up on my blog on the weekend.
That gets the root partition onto the HDD but I have yet to see if I can point another Pi at a nfs share (the 2nd part).

If I am understanding your configuration goal you want to nfs mount a /root partition from NodeA to NodeB which only has a /boot partition. I do not believe that this would be possible since NFS logic and other functionality would be absent without an already mounted /root file system on NodeB. NodeA would have to export its /root filesystem while NodeB would have to mount NodeA's /root filesystem. This would be done by NodeB's /etc/nfstab file which would not exist on NodeB.
Also there is a comment I read where someone wanted to boot a Pi from a USB device. My understanding is that the Pis must boot from an SD card since they have no BIOS from which to choose alternate boot devices. The config file can be modified to allow /root on a usb device but not /boot. I believe that this would prevent booting from a USB device.
Of course disregard the above if I have not accurately grasped your intended configuration.

LOVE the idea! One tiny correction - the Pi can't look for gravitational waves publicly right now :)
We would also want to talk about the team and how people can join.
I like the intro, but think we should do a bit more meat on BOINC, and then transition in to E@H, including a small blurb on its history.
Next question is how do we get them to notice?
