I'm waiting delivery of a 1700, Asus x370 pro motherboard and 8GB RAM.

I think you may find that too little memory unless its only running Seti.

I had to upgrade the memory in all my i7-6700's to 16Gb to run the Einstein OM1CV work units, They can use up to 1.5Gb per work unit. Some of the VM based work units from other projects can also be a memory hog from what I hear, so I am ordering 32Gb with mine.

I have tried to order one from PC case gear except their credit card gateway determined I was behind a corporate firewall and kept blocking my payment. I was at work. After I rang them they said it blocks for 48 hours so I'm in back off until next week 😩

Looking at the AVX one its r3345 by Urs.

The stock app is r3584 so is more recent than the AVX app.


And how do they compare ?
Does someone have used the benchmark tool ?
Any hope to see an updated AVX package ?

Can't tell at the moment because when running stock about all I was getting were vlar work. Since then opt app has picked up most normal work so it's going to take a while. Also I was running OpenCL iGPU app with stock but don't have it in app_info at the moment so that might effect results.

Question for Raistmer or Urs: Does the stock Linux iGPU app have the accuracy options that the Windows version recently received or is it likely to produce invalids.

Ask for Petri software. It's rocket science !


:) Thanks.

His Linux machine does not have an NVIDIA GPU and my optimisations are not in the OpenCL version.

Petri

I do have a couple of GTX1060's under Windows. Looking forward to when the Petri special is ready for public consumption.

Yes I have looked and found the ones over at Lunatics, however they're dated Jan 2016. Looking at the AVX one its r3345 by Urs. The latest one on the list is a SoG beta app dated Feb 2017 (r3602). Is there anything more recent available for CPU or iGPU.

Machine is an i7 with Intel iGPU. It was a Windows machine 2 days ago. I'm trialling Linux on it. I finally got Beignet to recognise the iGPU and its done a bunch of multi-beam tasks using the stock apps. The iGPU is around the same speed as the prior Windows app but the CPU ones are somewhat slower.

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.

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.
