Creation time is at 72 a second at the moment. That's the highest I've ever seen it. Most of my machines have a full cache - a couple of them I did have to kick start though.

0 results ready to send and number of units received in the last hour is at 55k but I would imagine those numbers will return to normal in the next few hours.

Actually, Seti@Home is not much fun any more, with the outages, droughts, problems, speculations...and CreditScrew.
Sorry about being so pessimistic, folks.... ;-)

@Chris, as Richard said, there is no need to do any further post-mortem on the problem. We know what the issue is with the download servers. Simple solution is to just comment out Vader server at 208.68.240.127 in the Hosts file and wait for staff to get it working next week.


Sorry, wasn't really a post about the server side problem. But more of a learning opportunity for me on how the client side works - not just with with BOINC or SETI, but with networking, specifically with DNS, load balancing, and proxy servers. All of which I had at home just for fun to see how they work but it's been awhile.

Added 208.68.240.119 to my hosts file 3 hours ago, haven't had a problem downloading since. I just commented it out to see what happens overnight. 123 work units in my cache at the moment. We'll see what happens over the next 9 or so hours.


1 work unit got stuck overnight and my Windows 10 machine was down to 59 work units. For whatever reason, This machine can't let go of Vader when it gets a stuck work unit. My Linux machines hit Vader too, but within an hour or 2 the auto retry works for them. If I had time today I would look to see if a connection from the Windows 10 machine can be closed sooner (thought I saw something about a 300 second timeout for connections) or some other tweak could be done with the auto retry perhaps.

My Linux machines have stuck downloads but retrying seems to get them unstuck.
Are you looking to see which of the two download servers that machine is trying to contact, at the time when the sticking happens?


Just turned on a bit more logging with my Windows 10 machine. A download just got stuck from this server:

1/6/2018 5:53:55 PM | SETI@home | [http] [ID#321] Info: Connected to boinc2.ssl.berkeley.edu (208.68.240.127) port 80 (#319)

OK, I use Freedome VPN and switching location a few times seems to have fixed my download problems.


I tried my VPN software earlier today (with the default location to US) but that didn't work. After seeing your post, I tried Mexico, that worked for the 5 I had stuck. Turned off the VPN software, and another 15 got stuck. Turned the VPN software back on to Mexico, and those 15 downloaded with no issues. Kinda strange.

Still having issues with downloads. I have been aborting the stuck downloads, but is it possible to hard code the IP address for the good download server on my Windows 10 machine?
If you know how to configure a hosts file, yes. But it's probably not worth it. The two IP addresses are swapped every 5 minutes to balance the load - just wait a few, then retry the download. It may not work first time, but it will do eventually.


I'll let it go and see if these 5 go thru

Related to this in the past I tried setting a second project (Skynet POGS) to 0 resource share to run only when CPU is free. Unfortunately POGs keeps downloading work which means the cache fills with POGs work and SETI gets pushed out as the full cache means no need to download new work from SETI. Is this problem with the way POGS behaves or have I got this setup wrong for a backup project to only run when spare CPU is available?


I too had another project plugged into BOINC, with my resource share set to 90 for SETI, and 10 for EINSTEIN. That ended up with hundreds of EINSTEIN work units. I just did this last Sunday, and have yet to work on any SETI work units. I was hoping for a balance of 1 EINSTEIN to 10 SETI (or something along those lines).

I used to have my resource share set to 1000 for SETI and 0 for EINSTEIN. That was the best setting to have for having my PCs work on EINSTEIN only when I have ran out and can't download any SETI work units.

Post:
I setup BOINC with 2 projects. S@H is set to Resource Share of 100, and Einstein at 10. This was done on a few different PCs.

BOINC downloaded a ton of Einstein work units on these PCs and BOINC is working on just Einstein work units for the last 24 or so hours on those PCs.

I would have assumed since the Resource Share is so much lower for Einstein, BOINC wouldn't have either downloaded so many Einstein work units, or put 90% of my PC's time into S@H.

The other setting I thought would be related to this, is under Computing Preferences - switch between tasks every x minutes. My PCs are set at either 60 or 120 minutes.

Hi Guys

I'm currently running two Pi3s headless with heat sinks and 40x40mm x 10mm cooling fans. Rasbian as the operating system on both and my temps are usually steady in the high 50C range when I bother to check them. They are both running SETI version 8 100% of the time on all 4 cores with a 5 day buffer of work units.

My recent average credit for both has been around 575 and 625 individually for a long time now. I have noticed that the slower Pi has linux 4.4.50 installed on it while the faster on has 4.4.21 but I am uncertain if that explains the difference in RAC.

When I started crunching the PIs seemed to top out at a RAC around 300 using application 8.02. When application 8.06 was released the RAC increased to the current levels. Processing rate increased from 1.62 GFlops to 2.89 GFlops when the application was updated.

Regards

William



Just curious on your setup with the fans. Is the fan part of a case? Or when you say headless, do you mean the board is not in a case with a fan next to it?

I'm running 2 PIs that are in a case that acts as the heat sinks with no fan of any kind, and only run 2 processors at 100% and they normally run at 55 degrees.

Thanks,
Chris

When I went to setup a 3rd RPI 3, Seti got the 1 confused with the other, and 1 high jacked the backend stats of the other. So I stopped at just the 2 running.

I have 2 Raspberry pi 3s. Both are set to run 2 procs only to keep temps down - even thou I have a case that acts as a heat sink, and to keep a couple of days work. I haven't touched them for months - I forget they are even there doing work.

Ah well, she has a point...the bill jumped over double


I too have to dial things back a bit. Thankfully with BOINC manager, you can set hours so 1 of my machines only crunches 16 hours a day, and on 2 others I'm using 2 less CPUs now. So over the next month or 2, I will be working on getting the electric bill down to something a little more manageable. Worst case I set all machines to crunch just 12 hours a day.

The question however still needs to be asked. What difference would it make to our world on earth if there was a 9th planet ? Would it cure cancers, stop wars, eradicate poverty?


It's fascinating to know a 9th planet may exist, but that's it. It would have no affect on life on earth.
