I do it a slightly different way. I run a twin Xenon m/c with 2 processors for 8 real cores. I have reduced the "use at most option %" so that I have 5 cpu tasks running and 2 GPU tasks running. The figure I used was 90%, which gave me 75% cpu utilisation.

Whether each GPU task actually gets a whole real CPU core to itself is a matter of opinion. What I do know is that in theory there is one CPU core spare for any task that needs it and the CPU's are not maxed out to their limits.

And in any case in Win 7 look at task manager, all CPU's are loaded equally whatever settings you use.

I agree with Mike, think you used the wrong installer, and/or wrong options. Else if using SOG work you need to use the tuning options else it runs like a pig.

@Chris

I think Annie is quite right, how can anyone prepare for the death of a parent,

My sister ran a plan past me when we were about six-and-a-half. We'd buy a caravan and bury our mom underneath it so she was always with us :)
Ah yes, the great plans of sisters. Hey mom, guess what, we built you a swimming pool!! Trip, splat, ouch - come here you two :-((

So my brother and I have never had what Annie has had to shoulder.
But we did have to support dad while he did what he did for mum. As I am famous for saying "Who is caring for the carer?".

My shoulders were "taken away" two weeks ago yesterday :((

I'm struggling with that.
Yes I know you are Annie, but sometimes situations escalate. My dad fought tooth and nail to put off mum going into residential care, but he and us had to accept that in the end it was the only practical way forward, because her needs had gone beyond what could realistically be provided at home. I don't think he ever forgave himself for agreeing to it, but the truth was that he had already done more than the average husband would have done, and he had nothing whatsoever to reproach himself for at all.

At this point in time Annie, you need as much support as your mum does, and I hope that is being provided.

Yes it is, but read a bit further.

That decision comes with a big sigh of relief, says observatory director Francisco Córdova, even though it’s not yet clear who will manage the observatory and where the additional funding will come from. “That adds a level of complexity and stress going forward,” he says. “But today we’re better off than we were yesterday.”

Though the observatory sustained damage from the hurricane and is still without power, its deep well provided water for local communities, and its helipad served as a base for supply distribution. Observatory staffers helped clear roads and allowed residents to communicate with others via short-wave radio.

It also provided the first indirect evidence for gravitational waves, spotted the first planets orbiting a star other than the sun, and—43 years ago to the day—sent the first targeted message to the stars as part of the Search for Extraterrestrial Intelligence, or SETI (a project of former observatory director Frank Drake, who happens to be my dad)
It looks safe, but we need confirmation of the money to be absolutely sure.

Posted 12 hours ago by Profile Chris SCrowdfunding Project Donor
Post:
Pyramidology is found all over the world. The ancient Egyptians, Aztecs, Incas, Mayas, Numians etc. Two main theories have developed for their proliferation.

Firstly as most cultures gods came from the sky, they were markers on the ground where the gods followers could be found if they returned as they had promised to do. Particularly so in the Giza ones which are laid out to represent the belt of Orion where they believed their gods came from. Allied to that is the Nazca plain and the hieroglyphs that can only be fully appreciated from the sky not at ground level.

The other theory is that the ancients believed that when the gods returned they would restore the faithful from the dead, so the leaders were placed within elaborate tombs to preserve them for the future, often with artefacts that they would need in the believed afterlife they would have.

Why they were built is still is up for conjecture, but in reality, there are massive stone blocks weighing up to 15tons, internal blocks up to 70 tons, so accurately placed, that we couldn't do it today. And the Baalbek terrace with 800 ton blocks. Plans of the Baalbek were given to international construction companies like Wimpey and Costain, they all said it couldn't be done even with the largest cranes in the world.

The estimated 40,000 workforce needed to drag and build the Giza pyramids by hand, would have required more food than the whole Nile valley could have produced at the time. But there they are today to go and look at.

Well today is my Seti birthday, 17 years ago I got bitten by the bug and haven't stopped since!

It's been a rocky ride, particularly during 2017, but the 2011 visit to the SSL lab at Berkeley to see the holy grail of the original server closet was worrth every second of 17 years work.

See you all this time next year :-)))

Absolutely, everybody does it all the time around here. Unless you are running BOINC << 5.0 or something.

Well that is news to me at any rate. Yes there was an element of cheating going on in Classic days, the vast majority was dealt with when BOINC came out. In any case what is the point in cheating, you don't earn any money for amassing credits, and if you do climb the leader board its by false pretences.

Opening a jar of Marmite to put on your toast and finding out that someone's been there before you and dipped a buttered knife in it, leaving flecks of butter behind in the jar.

I think Annie is quite right, how can anyone prepare for the death of a parent, it is simply something that you know is going to happen one day, but you just don't want to think about until you have to. But then it depends whether it is the result of a tragic accident, or a merciful release. The second is easier to deal with.

Dad nursed mum until the end in 2000. His own demise 2 years ago was within a couple of weeks after a fall. But for that he was 101 and set to make 102. So my brother and I have never had what Annie has had to shoulder.

don't quite see how we could know the necessary size an interstellar spacecraft, tenanted or otherwise.
Quite agree Michael. Arthur C. Clarke decided that Rama was to be 20Km in diameter x 54Km long, a ratio of nearly 2 1/2 to one. But that was just his idea in a sci fi book.

Post:
You've all made sensible observations, and yes py pendgs are around 1/3 of the total which is normal. Still don't quite remember it taking 6-8 weeks to settle down after an upgrade or new rig, but it's just me being impatient a bit I guess. A bit like going on holiday in the car with the parents "are we there yet, are we there yet!!!".

Consider the A380 Airbus body specs of 73m long x 7m wide, a ratio of 10:1, sounds more like a probe or just an odd shape of asteroid.

Ok, thanks for the replies. They just seemed a lot higher that what I remember themto be. First time I've ever run two cards in one rig, was rather hoping to see the RAC go up a bit quicker. No matter.

I don't know if anyone else has noticed this, but over the last couple of months my pendings are getting ever bigger in numbers. About 40% of everything I crunch is going in the pendings list. Yet some of my wingmen are running i5's and 970 cards and are regularly contacting Boinc. So why aren't they reporting work?

No wonder my RAC won't increase ......

If I did the post would get hidden :-))

The proof of the pudding will be next year at their AGM when they declare their annual accou8nts. We will see whether they have lost money or market share, and whether they can justify a deliberate anti-public attitude.

If in reality all they have done is to remove a non profitable part of their company operations, then it will be difficult to level accusations at them.


Next 20
