Quick Einstein tutorial for Folders
The way Einstein works is that it uses BOINC for the platform. Go to Einsteinathome.org and click Join. Einstein requires an account to be created on their site, so follow the link to do that. Download and install BOINC. Select Einstein from the list of projects. Enter your credentials, use "Ars Technica" for the team name. Einstein has both GPU and CPU work. Just like folding, the points system dramatically favors GPUs, particularly AMD GPUs. next is NVIDIA, then CPU work. Unlike folding, the projects award a specific amount of points whether you return them in an hour or just at the deadline.
Configuration of the clients takes place in two places - on the website in account preferences, and in the BOINC manager, which is the user interface on the client machine. The website "Preferences... Computing..." menu lets you group your machines into four different preference sets. Here is one place where you can set how many cores/threads you want it to use. The client is not multithreaded. One work unit per CPU. A GPU work unit also requires one CPU. "Preferences... Project..." is where you set what kind of work units you want. For CPU tasks, Gravitational Wave search O2 Multi-Directional awards almost four times as many points per core per day as Gamma Ray Pulsar work.
"Preferences... Privacy..." has two important settings. First is if you want other users to be able to see basic specs about your computers. Second is if you want your points to show up on BOINC stat aggregation websites. You should select yes here. BOINC is designed to offload stats to third parties. Just as most of us use Extreme OC's stats for Folding, you can use Free-DC's stats (among others) for BOINC. This can be a bit confusing until you realize the sum of the users doesn't necessarily equal the team because of users not opting in to the stats.
BOINC Manager on the clients operates very similarly to FAHControl. Here is where you stop and start activity, manage per machine preferences, and monitor the client. After setting things up, it may take a while to get things running smoothly because there are just so many settings to tweak and some interactions are not particularly intuitive. For example, I would run out of work units and my client would sit there. Why? Because I had somehow selected "ask before connecting".
One last note about Einstein and scoring. Each work unit is sent to at least two computers until a quorum is reached on a result. This means 1) you can wait a long time to get points for any arbitrary work unit, and 2) your result can get outvoted and declared invalid. A certain (very low) percentage of the work you do will be invalidated. This is an artifact of (I believe) the math libraries your computer is using vs somebody else's.
That is pretty much it. You can ask questions here (I think the Einstein thread has fallen off the map), or on the Einstein web site. BOINC supports a lot of other projects. MilkyWay@home is another interesting astrophysics project with an Ars team. Just like Folding, these projects publish results in scientific journals. Einstein recently discovered a rare "black widow" pulsar, which is slowly evaporating a companion star.
