When I reinstalled BIONIC I tried getting rid of their screen saver entirely, but when I ran "Show Graphic" inside the application it still ended up causing it to crash. It's just interesting that it's only SETI@Home that is having this issue.

I apologize if this is the incorrect forum to post this to, but I just wanted to make sure this was reported to the SETI@Home team.

I have a few different ARM machines running SETI@Home on on BIONIC version 7.6.33 that are able to run the "Show Graphic" option just fine. I recently added my MacBook Pro to crunch more SETI@Home data but found a peculiar bug when trying to show the screen saver graphic. If I attempt to add BIONIC as my Mac's default screen saver or if I click the "Show Graphic" from the BIONIC GUI after about 5 or so minutes I'm finding that this completely crashes my whole system. In both instances the graphic will just freeze completely and the whole system will become inoperable, forcing me to have to perform a hard shutdown on my machine. Tried uninstalling and reinstalling BIONIC and the same issue persisted. The issue only seems to be happening with SETI@Home, and I've verified it happens on other macOS machines as well.

I tried looking through the Console but couldn't find any crash logs prompted by BIONIC (at least that I could see).

My machine is running BIONIC v7.14.2 with the following specs:
MacBook Pro 15' Mid 2015
macOS Mojave (v10.14.1)
Intel(R) Core(TM) i7-4870HQ CPU @ 2.50GHz [x86 Family 6 Model 70 Stepping 1]
AMD AMD Radeon R9 M370X Compute Engine (2048MB) OpenCL: 1.2
INTEL Iris Pro (1536MB) OpenCL: 1.2
16 GB 1600 MHz DDR3 Memory

If anyone knows where I can dig up some more information on the system crashes that may help out the dev team let me know so I can forward that onto them. Is this a known issue or has anyone else experienced this?

Looking at your computers though, you don't seem to have an active Mac. Only ARM devices.


I run two SETI@Home accounts, one with just my Mac and a couple of other machines from time to time, another with five Raspberry Pi 3s (this account). Didn't notice any issues on any of nodes in the RPI cluster though, only on the Mac.

Same thing here as well. I have two tasks that have shown this issue. Specs as follows:

macOS 10.13.1
2.5 GHz Intel i7-7700HQ
16Gb DDR3 at 1600 MHz
Intel Iris Pro 1532 Mb
AMD Radeon R9 M370X 2Gb VRAM

Restarting project and machine. If that doesn't resolve issue then I'll abort this task.

Weird that it's all Mac users who are having this issues. I feel like any time BOINC has an issue its with Mac haha.

Using 5 Raspberry Pi 3s crunching SETI@Home 100% CPU time. I have them in a 3D printed rack and laid on their side with a big 24V fan pushing hair through each slot in the rack and keeping the CPU packet temperature at a nice chilly 38 degrees Celcius.

Works great, currently crunching almost 1500 average credit and am in the top 25% of average credit contributors.


My Raspberry Pi 2s are crunching SETI using only a single core (project_max_concurrent set to 1) and running other projects on the other cores.
Even though they are only using a single core they have a RAC of 80-90. If your Pi 3s are running on all cores 24/7 they should have a significantly higher RAC.
As I mentioned earlier I also have a Pi 3, but it gets very hot (> 75 degrees Celcius) when running SETI, so I am using it to run other projects now. When I did run SETI, it was significantly faster that the Pi 2's I have.
Based on my experience a Pi 3 running 24/7 on all cores should be able to have a RAC of at least 450.
Are you sure you Pi 3s are running full speed on all 4 cores ?



Yep I'm positive I'm running them on all cores. A single work unit takes about a day of CPU time to complete which knocks my RAC way down. Each of my Pi's have a RAC between 250 and 400 and it fluctuates depending on the work they get.

If you're going to be running SETI@Home for a long period of time, you're going to want some sort of fan on them. There are some on Amazon that are only $5 or so and plug right into the GPIO on the Pi. I used to run it like that, but the power draw was becoming too much. The 24V fan I have right now blowing on all 5 of them does the trick, but I had to split and wire up a DC24V power supply to work with the fan.

Again another classic "me as well"

Same issue happening after updating to the first public update of 10.13

Running a Macbook Pro 15'' Mid 2015
2.5GHz Intel i7
16 GB of DDR3 at 1600 MHz
AMD Radeon R9 M370X
BOINC v7.8.2

Right now not requesting any new tasks to see what tasks can and can and can't be run.

8) Message boards : Number crunching : Getting SETI@Home data location (Sky Map) (Message 1853888)

I'm running a small server cluster that's crunching away at SETI@Home data. The other day when I was looking through the BOINC Add-Ons, and I found the software SetiSpirit. The description for it is as follows:

"SETIspirit is free add-on tool for SETI@home users which provides information about the tasks, the SETI@home project status, workunits and credits, statistic charts and a detailed sky map."

I'm interested in the sky map portion of that. I know the default SETI@Home screen saver shows the numerical longitude and latitude of where the data that my computer is processing is from in the sky. This software takes it one step further and actually shows where the data came from specifically.

Is there an API or an XML file or any way that I can grab the longitude and latitude for myself and create my own sky map out of it?
