Finally found it ....
A year ago Eric posted a graph of the age of workunits (tasks) residing on the server RAID giving a good snapshot of the client turn around times.

Even those tasks which the graph shows as hanging around for 60 days wouldn't be there if the client had a smaller cache in the first place.

Thanks Richard for those server settings. Now if we could just find someone with some time to try different settings and document the results of each.

When shrinking cache size, it might be best to do it in 3.5d steps every day, so that we don't get that HUGE outbound of resends that Richard noted would happen.

Remember one thing when using a 10 GA cord - Your wall only has 14 GA in it.
Keep a close eye (or finger in this case) that your wall plug, wiring and cord end don't get warm.
And don't just pop a 30A breaker in now that you have 50% 10 GA wiring on that circuit.

Also, WELCOME BACK KITTY,
We missed you!

With the growth of threads in the current CPUs it might be better off seeing if the developers are interested in programming a multithread (4?) CPU app.

Anybody know what happens to the noisy data (noise bomb) data when it is pulled from the server because the server can't cope? I am wondering doesn't get discarded or does somebody else look at it
I would imagine they will run them through at some point here. I server can handle them - just not all at once!

If they are split one at a time they will whistle their way right on through ... but takes some babysitting and the hard to find TIME.

Exceeded runtime limit is usually a result of excessive rescheduling in my experience.

That's on par with my i5-4590 @3.3GHz which is at 7400 right now. https://stats.free-dc.org/charts/hostdaily.php?proj=sah&hostid=8457417
Your could definitely run more than 4 tasks on that machine though.

When you found that machine I mentioned that is a good overclock chip. I real quick look shows 4.7GHz on it :)

. . Well if the blc41/42 tasks prove to be long and slow it may balance out a bit. Here's hoping :)
A rather mixed bag. I've had 2 that took 3 times as long to crunch, and another 2 that got done in almost half the usual time.
Some are non-vlar tasks, so I guess they are BLC shorty\ies.

Yes the servers are handling it quite well considering the load.
Once the database lag and assimilation catch up (from maintenance), performance should improve with them having less load as well.

I wouldn't expect it to get any better for overflows until the next tape series - there are a million slower CPUs out there with 24h plus cache, so they are still working on normal runtimes. As they get into these tasks ... more and more returns.

Just a note, it may not neccessarilly bbe your CPU temp, but the board temp.
With that being said, airflow through the case IS important. Try turning a couple of fans around to move air through the case rather than pressurize it.
Even a 92-120mm fan near the MB just to move some air around - you lose that airflow with an AIO cooler.

Also try taping up cracks/holes in the case. It does make a difference.
Like that 140mm fan hole that has a 120 in it, there is an unneeded space.
And PSU inputs are usually much larger than the PSU, tape up a little.

I was surprised how much you can change things with a little time, when your cooling is borderline.

I haven't watched it for awhile now but I thought they were going by record date still ... sorting within the filename.
And I do believe they have the ability to push tapes ahead of queue for what they want results back fast - we have seen that haven't we?

Remember as well the difference between 3GB/6GB on the 1060s is 9/10 CU as well.

So with the 3GB models you get 9 CU, 6GB gives you 10.
OR 10% loss over the 10CU.

This may not hold true on every model/brand of the 1060, but it's something to watch for.

Cool, thanks. I got it working, albeit a bit wonky at the moment. I went with SSE4.1 for MB and SSE3 for AP.

And did a manual install of 6.10.58, but Manager is angry about running. I don't need a GUI on the linux machine though.. i just use Manager from my daily driver to remote connect.

4770K is many orders of magnitude faster than the Sempron 3500+ was. :)
For a Gen4 CPU I think AVX would be the best.
I looked it Up and that 4770K stomps on your AMD 6100 :)
I think those CPUs were also Overclock monsters :D But not the RAM.
The LGA 1150 boards are pretty cheap if you need a better layout.

But first things first, finish setup and let it run untouched for a week to see if it reliable.
It would actually make a pretty nice Daily Driver.

I am curious. Given the riser cards can use USB cables. Has anyone tried driving a gpu card via a USB plug in instead of the pcie to usb card?
It might give us an "off the wall" lift up if it would work.
Tom
Give it a try, What could it hurt?? :D

I'm not sure about "off the wall" But I'm fairly sure "through the thin blue air" would apply.
How do you think the MB would handle the 12V that gets feed back trough it from the USB to PCIe card?
If it doesn't work on one brand of board try others, and report back if it is brand specific.

I think you actually added ncpus into your CC-config file. That method is a little different than restricting to 75%.

<ncpus>N</ncpus>
Act as if there were N CPUs; e.g. to simulate 2 CPUs on a machine that has only 1. To use the number of available CPUs, set the value to -1 (was 0 which in newer clients really means zero).

I have only had that type of a problem on 1 computer - happens that is a 1700x/Gigabit board.

In my case it is when a PCI extender is flaky and drops offline. That takes down the Ethernet, be it wirer or wireless adaptor.

All I can say is leave NVidia-smi open to see if they go down together.
