1) Message boards : Number crunching : Observation of CreditNew Impact (Message 1385282)
Posted 425 days ago by Profile doublechaz
Seems to me the credit has varied a good deal with each new version of the app going back more than ten years. Who cares? We're all in this project, the only place where scores for this project have any meaning.

I came here to see if I could find out why my RAC is half what it used to be. The answer is that everyone is seeing the same. It's an artifact of the version change. Nothing broken. Ok. Question answered.

Nothing to whine about. Thanks everyone for clearing that up.

Nice. Maybe he can rattle a chain towards the proxy or something.
Thanks.

Well, a few others can get through from time to time so I guess I have bad timing and I'll consider the matter closed. Thanks everyone for taking time to look in on this.

Are you working by IP only? All dns queries that I run result in a no answer error.

That's cool about not passing on contact info. If you can reach them could you pass on a note to use some of his vast free time ;) to look at connectivity from a couple sources to track down the disconnect? Thanks.

Very odd. It's been down all week from my perspective.
I've been using DNS searches from various web services to rule out some kind of local or regional DNS failure.

Time to do some searching and see what GTLD servers are in use upstream from me. That should be fun.

Yes, I've seen all that whois. But if you do a dig for the authoritative name servers you get no answer. That query should be handled by servers above him so it isn't just that his servers are offline. If you do a dig for any type of record at the servers listed in whois you also get no answer. So if anyone can pass this along to him, it may be worth while.

This is different than server problems. The domain name no longer exists as if someone forgot to renew. Does anyone have contact info that doesn't end with @enigmaathome.net that they can share? If he is coincidentally having server problems then he may not be aware that the Domain has expired.

Their Domain name seems to have expired.

Does anyone around here have connections to them? Does anyone know if they will be back?

I'm just curious if I should dump all the ready to report work I'm holding for them since they were my primary backup project behind seti. Thanks.

I've been working on Distributed.Net longer than I've been on Seti. They seem to now have a windows BOINC version of their project. They could always use some help.

Stop pushing it so much. You are interfering with *my* ability to upload. ;)
11) Message boards : Number crunching : Problems... (Message 979205)
Posted 1625 days ago by Profile doublechaz
I'm getting the shakes, too.

But don't forget that seti is not the only thing these guys do. Perhaps today is a big meeting with the Grant Review Board and they feel that getting some money for the project is important. Or perhaps today is the day they have to meet with a group of professors from around the world about remote sensing techniques for penetrating galactic scale molecular clouds. Anyway, this is just one project that they are working on so they may not have been working this problem from 8 to 5 as we might hope.

I really want it working too, but I can live with it no matter when it comes back online. Take a deep breath with me and we'll check back later.

Some people don't like it that way. They seem to take it like telling them the week after they get divorced that there are other women.

Personally, I'm single so I like other women. ;)

There are a couple places around here in the mountains where jake brakes are prohibited because of the avalanche danger. They really are loud.
14) Message boards : Number crunching : Partly killed CPU? No magic smoke either... :-( (Message 908871)
Posted 1895 days ago by Profile doublechaz
I did burn a CPU once long ago this way. I was overclocking and running Seti Classic. After a long time like this it became unstable. I had an identical MB and did that switch as well as RAM. It was the CPU. It wouldn't even run at factory spec after this damage. I had to underclock it to get it stable again.

Are the servers in question running Linux? If they are then I believe I can give you the answer of how to stop the dropped connections.

change the value in /proc/sys/net/ipv4/tcp_retries1 from 3 to 6
change the value in /proc/sys/net/ipv4/tcp_retries2 from 15 to 60

That way when the pipe is full and the router is dropping packets (this is what is happening after all) then there will be a much higher chance that the entire connection won't fail and I won't get 75% through downloading the same workunit 3, 4, 5, I've seen as many as a dozen tries of downloading most of the unit before success. That should be something like an 800% increase in effective bandwidth during the congestion periods.

I've used the above technique (actually 9 and 90) during congestion to resque a starving client with great success, but the correct place to make this change is on the server.

I hope that someone is willing to try this for a week or so and that they read this thread.

Is it the fibre itself that is 100Mbit or is it the interfaces in the routers that are limited? I thought you could run Gbit that far over fibre with the correct WICs in the routers. Certainly it is multimode fibre to go that far.

I work at a wireless ISP, so I don't know fibre that well.

As to a wireless link you could use a couple RouterBoards from MikroTik with a pair of wireless A cards at each end. Then teach it to use the Nstream Dual protocol instead of 802.11 and you could get something like 40Mbit full duplex. That wouldn't cost much. I think we could raise donations for the couple thousand it would take.

I can contribute technical skill on the RouterBoard setup if there is interest.

I'll hit 1 million any minute. I should have hit it right around the new year, but I shut off a bunch of stuff to go out of town for a week. I shoulda left it on.
18) Message boards : Number crunching : Why can't I maintain a cache of x-days worth of WUs? (Message 629182)
Posted 2554 days ago by Profile doublechaz
I figured this out.

5.8.16 CC ignores my cache settings.
5.10.0 CC honors them.

At one point 5.10.0 was available for download, but now (and when I installed the newer machines) 5.8.16 is what you get.

I've copied 5.10.0 from my older machines to the newer, and now they are all working correctly.

That should keep them out of weird EDF mode with overworked projects while seti can't or won't get work.

Posted 2560 days ago by Profile doublechaz
The machines with problems are all dual 1.2 GHz. They are 100% uptime and marked as such in the venue. They just refuse to cache seti. They will cache several abc or spin units. My PII 350 always has more WUs cached (2-5) than the new dual PIII 1200, but the old PIII 1000 has a couple dozen.

Posted 2560 days ago by Profile doublechaz
Yes, but seemlingly his policy boss doesn't understand that packets and the payload of those packets are the same thing WRT data delivery to a network of computers. The policy is 'no active direct or proxy connection to the net. But any *data* delivered to the cluster is fine as long as it doesn't slow production jobs, or compromise security.' It's a subtle wording difference that we don't see, but that boss does. Doesn't matter if it is a real difference or a semantic difference. The boss said.

I think you can create a share on the head for each node with an instance of boinc in it. The head can run each in turn to get a machine id and cache (lying about the host name so that they are all separate machines) and then stop. Then each node can run in that share to process. Every 8 or 12 hours the nodes all shut down the boinc process. The head runs each in turn to return/fetch WUs. Then the nodes pick up again. Should be a fairly simple scripting job apart from the getting unique machine IDs for each instance.
