Thank you Andrew,
I am certain that I will find something new and exciting. It selling myself that gets me down.
That and the fact that my age is against me. My earnings peaked when I was in my 40's and seem to keep going down. Not the best trend.


If you are making enough to pay your bills, then you are making enough, even if your earnings "seem to keep going down".

You might start exploring "side jobs" and see if it works well enough to pursue instead of what you are doing now.

Don't feel guilty about taking "personal time" from work. Sometimes the best thing to do is stay home and "goof off".

For a little while.

Goddess bless.

Your local public library may have a collection of audio books that can either be "read" on a regular CD player or an MP3 player.

This morning, I just noticed my E5 box wasn't running. My only excuse is I have been "busy".

It looks like it may have been off for a month. :(

The good news is it looks like only 5 tasks are past deadline. Unfortunately one of them is an AP. I don't have a clue why it shutdown. It is on a UPS and has a fan blowing in the front.... Gremlin's? Nah.... maybe it got lonely (see below).

Oh, well. Teach me to assume all is well in the "server" room and not wonder in there daily.

obtw, it was getting too hot in my home office and I needed to study, so I "moved" all my "desk" stuff to a "study nook" in another room. So I don't commonly get in here much. At least my little box kept running :)

The only way to get through the outage with the special app is to do some bunkering of tasks before the start by rescheduling. You can bunker up to 1000 tasks and not exceed the BOINC limit.


So could you point me to a url/message that describes "bunkering"?

Thanks,

As we seem to have stopped the threads about the recently departed I am posting this here, as I sure many of us have read books, to many to mention, and articles (Byte magazine etc.) by Jerry Pournelle

From Jerry’s son Alex:

I’m afraid that Jerry passed away.
We had a great time at DragonCon.
He did not suffer.

R.I.P.


Another Author I have read a lot of, will no longer provide new things to read. So just have to re-read some older JP stuff.

Notebooks/Ultra portables even with their larger screens are pretty close in weight these days.


As soon as you move upto Ultra portables they get quite expensive unless you can buy them used from a higher quality useddiscounter.

So there might be a price issue too.

Post:
My question would be could you get that many cards to fit on the motherboard? I guess you have to be assuming the "extender cable" thingies because I don't see how you could possibly fit even a "mini" card onto 3 of those slots in a row.

If you assume one thread per gpu task and hang gtx 1080's off it. Apparently they run 3 tasks. So 19 X 3 = (starts counting on fingers and toes )[oh, there is my Windows calculator] its something like 57 threads you would need for "full production" under Seti at least.

So without even examining the under pinning hardware lanes etc I would find it hard to believe it would be a good idea for Seti at least. Unless the SOG code could be re-written so it doesn't require the full attention of a core / gpu task (is that what the Cuda80/Alpha test is about? I have lost track).

Looked at ebay and the Gtx 1060's appear to have returned to rationality. Going for just a shade over $200 in the "buy it now" listings. (several Votac mini's).

I am seeing Gtx 1080's from $490 to $550. Hmmmm..... (licks lips....).

Gtx 1070 in the $460 to $490 range.

So has the bubble collapsed?

10) Message boards : Number crunching : Anyone been able to get an APU eg. A10-xxxx or A6-xxxx to run at full speed with the cpu's and gpu at the same time? (Message 1885622)
Posted 23 Aug 2017 by Profile Tom Miller
Post:
I used to have an A10-6700 and now I have an A6-7310. Both refuse to run both the cpu and the gpu at full speed at the same time. I got to poking around with the HWINFO64 and if the gpu is running at what appears to be full speed then the cpu's are running at maybe half speed.

The results mean my cpu's are taking on the order of 12 hours per task. I have a GT 710 that used to take about 3 1/2 hours for a gpu task and I think that is the right ballpark for the "R4" gpu I have.

But a 2Ghz cpu with AVX (although I am not yet running Lunatics) shouldn't be taking 12 hours.

After looking at the HWINFO64 cpu results it dawned on me that this would be a case for "-use_sleep" and its related parameters so I am experimenting with them now.

Does anyone have any ideas about what would allow the cpu's and the gpu to run at near full speed at the same time?

Thank you,
Tom

Posted 23 Aug 2017 by Profile Tom Miller
Post:
An update: I now have 6 dimms (3 dimms per socket) and now runtimes are ranging from just under 1 hr to 2.5 hrs depending on the type of work being processed using the AVX app

i.e I added 2 more dimms this week(last week for us Australians due to the time difference)
Running 29 cpu tasks + 1 GPU


Those are very respectable cpu times. It looks as if a "AMD Radeon R9 200 Series" should run gpu tasks in the 15 minute range for AVX.

So what I am looking for is experience/advice on what are likely the "best" settings in the mb*SOG.txt command line for essentially an "entry level" ATI type gpu that will release enough cpu cycles to let the cpu's run at credible speeds instead of 12+ hours / task.


Sorry mental error. The gpu MB*.txt file is not necessarily the "SOG" file although I do see one coming. I am currently running "nocal" tasks. :)

Posted 23 Aug 2017 by Profile Tom Miller
Post:
I just picked up an A6-7310 with an "R4" gpu. It is running under a stock Win10 OS. I haven't tried installing any older drivers.

Boinc/Seti is downloading and running "open_cl_nocal" I assume it makes sense so the question is something like I thought "nocal" meant gpu tasks couldn't be run? Apparently I am wrong. So the other question is, if running a backlevel gpu driver will speed up processing, what is the recommended non-current ATI driver?

Thanks,
Tom

Please forgive my lack of response. I am dealing with a family bereavement at present. I will reply to the points addressed to me as soon as I can.


Please do not get stressed out about "responding promptly". The whole point of this medium of communications is to keep a conversation alive and available at whatever pace we wish.

I am sorry to hear of the passing of a loved one. I understand. My wife has passed "recently". And I am not over it.

You have a bit to go with that rig yet Tom as my 3GB 1060's are good for 21K each and for that rig of yours I'd expect a RAC around 23K using all it resources.

Cheers.


It looks like it peaked at someplace near 18,200 RAC before the Tuesday black out window hit. I am slowly, as they run out, removing the "other" projects. Once I get down to the WCG and throttle it to 2-3 cores I will be turning on the cpu tasks for Seti to see how much further up I can get it. I want to keep a "small" thread of WCG task running but it doesn't do "small" very well so I am just going to have to let them start running out of time until the scheduler figures out to not download so many.

Post:
I owned an A10 for several years, trying to get it to run Seti effectively. I couldn't get the CPU's (4 cores) and the integrated GPU to both run at "full-tilt." Basically if the GPU was running at full speed the cpus were not and vice versa.

I recently bought an A6-7310 (2Mhz+ turbo & 4 cores) laptop for other purposes (including practicing my Win10 support skills). Anyway, to make a long story short, the same issue has shown up.

When I got to looking at the hardware with HW64Info, I discovered that even when the Task manager was reporting near 100% the cpus were actually running substantially throttled.

It then occurred to me that -use_sleep which releases cpu cycles to allow more cpu processing and its related commands -use_sleep_quantum etc. Might be profitably used to allow the cpu's to run at 100% while letting the gpu to run near 100%.

So what I am looking for is experience/advice on what are likely the "best" settings in the mb*SOG.txt command line for essentially an "entry level" ATI type gpu that will release enough cpu cycles to let the cpu's run at credible speeds instead of 12+ hours / task.

Any ideas?
