I haven't been able to find anything that mentions how much memory the X370 chipset/CPU will support. I'm hoping (given the Ryzen 7 1700 has 8 cores/16 threads) that it will support up to 32Gb of DDR4.

Is that fixed chirp version going to appear on beta as 8.06 then? Currently still getting 8.04 on beta as stock app on Pi2 and Pi3.

So that has me looking at a couple of Asus Prime X370 motherboard with Ryzen 7 1700 (8 core/12 thread 65w) machines to replace i7-4770K machines (which pull 140w just for the CPU).

Memory support is 2400Mhz which seems rather slow unless Asus give their overclocked memory options.

Have attached a single Pi2 and a single Pi3 to Seti Beta to help out with testing. They've both picked up the 8.03 app and have four work units running.

Got blc05 vlar work on both Pi2 and Pi3.

Pi3 on 97% done after 23 hours and 6 mins so looks like it will be around 24 hours
Pi2 on 30% done after 23 hours and 8 mins so looks like 6 days.

Also, windows boinc manager getting really slow when fails to connect to another computer.
It's a bug...

EDIT: but I have parallella's IP listed and empty password file now - still windows boinc manager can't connect. What's wrong with it? (BOINC 7.4.42 x86)

You did put the host names or IP addresses in remote_hosts.cfg as well? That is the names of the computers you're going to allow to connect to the Parallella. Also you might need to have it listed in /etc/hosts.allow

I found that for whatever reason my Pi's and Parallella's wouldn't appear on the routers list of connected computers by name but they always work if I use the IP address. I assume this is either a bug with the router or Linux (on the Pi/Parallella).

If you want 7.6.33 you can add Jessie-backports and get it from the standard Debian repo. You just need to include it in /etc/apt/sources.list and then do an apt-get update followed by apt-get install -t Jessie-backports BOINC-client.

Eric has fixed the AUTHORS file problem and the host is now running its first Seti work unit.

I installed beignet-opencl-icd from Jessie-backports. Its version 1.1.2. Unfortunately the version in there doesn't recognise the HD Graphics 530. The version in Stretch is more up to date (1.2.1) and does, but then all the Einstein apps will fail if I move up to the Stretch release, so I guess no iGPU any time soon.

Eric reports:

I fixed the AUTHORS file on main. The same problem probably exists on beta. I will investigate between meetings today.

Claggy

That was me. I sent Eric a PM pointing him at the "Linux app query" message thread where I have setup one box as a Linux host and it errored out all the WU due to size mismatch. I guess he got confused who sent the message. I can confirm the host is now crunching its first Seti work unit.

Einstein tasks all failed with segfaults. I don't think their apps work with the Stretch release. I reinstalled the machine with Jessie and didn't bother with iGPU drivers. Its now crunching 8 gravity wave work units.

I still need to try optimised Seti apps but the Einstein gravity wave work usually takes from 8 to 16 hours to run.

Got debian installed. Managed to find intel GPU drivers and install them as well as beignet. BOINC installed and attached to the project to try with stock. It seems the linux64 app is corrupt (well specifically the AUTHORS file).

SETI@home 02-01-2017 03:08 PM Started download of setiathome-8.00_AUTHORS
SETI@home 02-01-2017 03:08 PM Incomplete read of 849.000000 < 5KB for setiathome-8.00_AUTHORS - truncating
SETI@home 02-01-2017 03:08 PM Finished download of setiathome-8.00_AUTHORS
SETI@home 02-01-2017 03:08 PM [error] File setiathome-8.00_AUTHORS has wrong size: expected 924, got 0
SETI@home 02-01-2017 03:08 PM [error] Checksum or signature error for setiathome-8.00_AUTHORS

Tried to use wget to pick it up and its 849 bytes but the project says its supposed to be 924 so it marked all CPU tasks as download failed.

The OpenCL tasks crapped out as well but they start and run for a few minutes and then fail, probably a driver issue.

I'll try Einstein next and maybe the Seti optimised ones after that.

Post:
After much frustration with Windows updates I am looking at switching to Linux for my CPU crunchers. Are there optimised apps available, as in AVX or similar to take advantage of recent processor features?

I'm familiar with Debian so that will probably be my target OS. Initially I am looking at switching my i7-6700 machines.

I ordered a couple of GTX1060 (3Gb variety). They're in transit at the moment.

I haven't been able to run anything in the last couple of days due to the heat (38 degrees C in Sydney today).

We finished v7 ages ago. We're on v8 now. Stop your BOINC client, delete the app_info and restart BOINC. It should get the stock app.

When I will get feedback from already provided build I could try to disable this pragma too.

Sorry for the delay. Work intervened.

Another set running using new app. Same hosts as before. I also snagged some guppies this time.

Looking through the results it would seem v8.19 supplied by beta validate most of the time. The r3525's are almost all inconclusive or invalid.

So try test iGPU build.

8 cooking on beta using 8.19 app as we speak. Will take a couple of hours for them to be done. All are Arecibo at the moment, no sign of guppis.

If it helps I have a bunch of i7-6700 (Skylake) machines with HD Graphics 530. All are running Win7 x64. Currently have GPU disabled in BOINC due to this issue. Happy to help test on here or beta. Currently have driver 4501 on them but have older drivers as well.

After Christian Beer changed the beta validator for BRP4's I found them all pretty much validating. Unfortunately when one selects beta apps at Einstein it gives all different work types which didn't work on HD Graphics 530.

Post:
Most of my machines are i7's so they get 100 / 8 threads = 12.5 WU per thread.

If we expand on that by saying we get 12.5 x number of threads then it could work for the smaller (single thread) machines as well as the larger (56 thread) machines. I would suggest we make it something like 15 per thread. Its simplistic and achievable with the current infrastructure.

A more long term approach might be to increase that number based upon the average turnaround if the host is considered reliable. It could also be applied the other way to reduce the number if the host is unreliable.
