Engadet confirms the rumors here:
AMD's $749 Ryzen 9 3950X is the 'world's first' 16-core gaming CPU
Today during its E3 2019 press conference, AMD announced it's pushing gaming beyond 8- or 12-cores, with a new "best of the best" CPU. The "World's first 16-core gaming CPU" is the Ryzen 9 3950X, which will be available in September for $749. Outdoing Intel's 8-core gaming CPU, CEO Dr. Lisa Su said this chip has "the highest boost frequency in our stack" that goes up to 4.7Ghz, with 72MB of cache and operating at 105 watts.

I found the problem.

A snippet from my app_config.xml:
<app_name>astropulse_v7</app_name>
<plan_class>opencl_nvidia_100</plan_class>

A snippet from my client_state.xml: 
<app_name>astropulse_v7</app_name>
<plan_class>opencl_nvidia_cc1</plan_class>
<file_name>astropulse_7.08_x86_64-pc-linux-gnu__opencl_nvidia_100</file_name>

I changed app_config.xml to use opencl_nvidia_cc1 and BOINC started up without the error. I thought the filename's ending opencl_nvidia_100 was the plan_class, was I wrong?

This begs the question: why don't others with the same app_config.xml get the error? Because this host was setup about two months ago?

I don't have an app name in app_config.xml. I thought the app_class would default to the proper app. Can I override app_class by using the app name instead? I assume that an app update would break app_config, no big deal to re-edit it.

I tried editing app_config.xml and re-entering info JIC there was an invisible character, no change.

I'm a noob at using cc_config.xml but any error or warning makes me wary. I'd check in between <max_tasks_reported> and </max_tasks_reported> to see what BOINC thinks is unrecognized. Perhaps removing that block and testing will help.

After following Keith's advice to get VNC running I suggest modifying /boot/config.txt so VNC will always use the same screen size. An alternative is to buy an HDMI dummy plug that convinces the RPI that a display is attached.

Edit /boot/config.txt using sudo, I used the command:
 sudo nano /boot/config.txt
Uncomment the line with hdmi_group and add a line so you have this:
hdmi_group=2
hdmi_mode=50

hdmi_mode=50 is 1440x900, which is a good size for the VNC windows on my Macs. I forget where online the hdmi_modes are documented...

I have Sense HATs on all three of my RPis. I wrote a Python script that graphically displays core and memory usage, temperatures, humidity, and also pings my computers to see if they're alive. I added the ping when a cheap notebook hung too often. I could glance at the Sense HAT and tell when it died. It got so bad I scrapped it.

As example of how far the technology has progressed in these two decades: I happened to save a screenshot of the old SETI@Home app. pre-BOINC... this is from 2000:

Thanks for that, it brought back fond memories. I ran SETI and then Folding@home on Macs before BOINC. I remember turning SETI's fancy graphics off because it slowed down the GUI too much.

You may want to go with Sierra. Sierra will run both the older zi3v App which runs without any trouble, and the newer 0.98b1 App which still has the problem with missing Pulses after first boot. With El Capitan you can only run the Older CUDA 8.0 App as you can't run CUDA 9.x in El Capitan. To run CUDA 10.x you need High Sierra, but, for now there isn't any advantage to running CUDA 10.x. Perhaps later, depending on what it takes to run Turing, it might better with something newer. But for now, Sierra is the best for SETI, and trouble free with the zi3v CUDA App.

TBar: Thanks for this info. I'm running Sierra on my two production Macs (iMac & MacBook Pro), both have been very reliable.

Your Internet Issues, (IF on the Mac Pro), with High Sierra and Mojave "COULD" be the Original Apple WiFi Card as it is NOT "AC" Capable... (I didn't actually think that High Sierra had this issue, BUT I know from InsanelyMac and elsewhere that Mojave DISABLES ALL prior WiFi Cards NOT "AC & Bluetooth 4" Capable.)

Many thanks, I do Mac & IT support for a living (semi-retired, mainly the tired part...) and haven't heard about this particular issue. FWIW: Mojave did not disable my dual-CPU Mac Pro's original WiFi or Bluetooth. Both my Mac Pros are hooked up with Ethernet as the primary connection. Out of habit I connected my dual-CPU's original WiFi Card to use 5GHz N on my AirPort Extreme tower/ac. My single-CPU has neither WiFi nor Bluetooth cards. The dual has lost networking far more often than the single. I just disabled WiFi and Bluetooth on the dual, let's see if that cures it.

JUST found this CHEAP Founder's Edition GTX-1070 8GB Card with DP x3, DVI x1, HDMI x1 Ports on e-Bay. $200

What I can spend will depend on what I can sell my two new Radeon RX 560s for. They were only about $130 each.

TimeLord04:

Thanks for the wealth of info but those prices are way too high for my budget. For my single-CPU Mac Pro I may downgrade to El Capitan since I won't use it for anything but BOINC.

Both my Mac Pros running Mojave run headless, so I'm not overly concerned about not seeing the boot process. On the rare occasion that something really goes amok, I put the original GT120 video back in just to watch the boot.

Common misconception: Mojave will boot without a Metal-capable card. You just can't install it without one.

All my High Sierra and Mojave Macs lose their Internet connectivity far too often. It's not my network, all my other computers are fine. Right now I'm downgraded my 2010 MacBook Pro 17" from High Sierra to El Capitan.

I use my dual-CPU Mac Pro as a SpamSieve Mail Drone. It reads mail 24/7 and filters out the spam (I do my own filtering for my personal domain). I do this so I don't have to wade through 200 spams/day on my iPhone. I'm looking into doing this in VMware on my main iMac. But even the virtual Mojave has network (and hanging) issues...

Do you have an app_config.xml file in the Seti projects directory allocating one cpu thread for each gpu thread?

I didn't, I just added it to the Linux machine to make sure I did it correctly.

Cruncher-American is running SoG under Windows which is entirely different animal from running Cuda (special sauce) under Linux, CyborgSam 1 w/u per GPU is your limit under Linux.

Bummer. Will Mac BOINC run multiple WUs/GPU? If so I may swap GPUs around (which also means downgrading from Mojave on the Mac that gets the NVIDIA GTX 1060).

My Jetson Nano arrived today. My 5V 4A supply arrives tomorrow so it's running on a micro-USB 2A supply. Tomorrow I'll kit-bash an old humongous heat sink that's bigger than the board. It shouldn't require a fan.

I don't like the newer Ubuntu GUI. They're mimicking Apple and Microsoft's sparse interfaces with hidden controls. I'll try and install xfce since I'm familiar with it from Mint. I'll copy my BOINC data off the Jetson first since I may blow up Ubuntu...

I have the stock BOINC running. For now the Jetson will only run SETI. Out of the box SETI isn't using the GPU, is this expected? Since I new at this, any tips for setting up the Jetson? Any custom binaries to speed computation?

I can report that the HDMI emulator works as advertised. Reports itself in the configuration settings as a display which allows you to select the display resolution you want to use. After installing the emulator and rebooting, I could remote in via VNC connection by Remmina and have the desktop the proper size. A cheap and easy solution for headless use of the Nano.

I run my Jetson headless, I also use an HDMI dummy plug. I chose x11vnc VNC because it works with Real VNC Viewer on my Mac. I had to change x11vnc's setup to accomodate Ubuntu not using the standard home directory Xauthority location.

Depends - are you running > 1 SETI WU on that GPU simultaneously? If so, you need 1 CPU for EACH WU on the GPU. That is, the CPU goes with the WU, not the GPU. For example, on each of my 2 crunchers, I have 2 GPUs each running 3 WUs, so they require a total of 6 CPUs on each machine. The app isn't multithreaded, so 1 CPU is enough per WU.

In the Tasks tab SETI has one task. Why isn't SETI grabbing the rest of the free CPU?

Is my NVIDIA GTX 1060 capable of running multiple WUs? If so: how do I do that and what's a practical limit?

TIA,
Sam

I'm contributing to 4 projects: SETI, Einstein, Rosetta, and WCG. All are allocated an equal resource share.

I lowered the "Use at most ... % of the cpus" to ensure that a CPU is always available for each GPU. Yet SETI only uses a fraction of the free CPU.

Right now my dual-Xeon Linux mobo with 16 CPUs and an NVIDIA GTX 1060 has 1 Einstein task, 7 Rosettas, 7 WCGs, and 1 SETI at 0.405 CPU. SETI is the only task using the GPU.

My Mac Pro single-Xeon with 12 CPUs and two Radeon RX 560s has 1 Einstein using 1 CPU & 1 GPU, 5 Rosettas, 5 WCGs, and 1 SETI at 0.235 CPU and 1 GPU.

Is there a significant performance hit when SETI uses less than 1 CPU for the GPU? If so, will lowering "Use at most..." a bit more so another CPU is free help? Will the increase in GPU performance offset the loss of a CPU for other projects' tasks?
