PPS SV to Ruby. I must be getting old -- I can still remember when that was as far as one could go!!

Thanks to mike et al, and thanks to Rackspace. If I ever do need a cloud I know where I would look first!

Under CUDA there is a limit on the size of numbers the GPU can handle. Does this limit still apply in the OPEN CL version or can we go higher?

in the advanced manager window go to Tools:Options:General and tick the box 'run at login'.

There may be slight diferences if you are running a different version of BOINC.

Curiouser and Curiouser - as Alice would say -

I tried to find some 'common-link' between those 3 PCs - and came up empty. Different procs - 2 Core-i5 notebooks, and a Core-i7 Desktop - different flavors of Win7 - different versions of BOINC even!
I use BAM manager on all my PCs and generally don't touch the settings otherwise, so I'm pretty sure it's not a settings-problem - and NONE of them are overclocked in ANY way - and have run all other BOINC tasks faultlessly for many months!

So I took one of them (Computer number 259651) and 'went the whole hog' ..

I uninstalled (MSSE) Antivirus completely (often a cause of these kind of weird errors), then proceeded to abort all tasks, reset, detach, and finally completely uninstall BOINC and delete the Program Data folder entirely, before rebooting and doing a complete re-install.

Result? - Absolutely no difference whatsoever!

- I Do have some further Info though.. - It appears the task processes are not stopped after being aborted, and carry on running, taking up CPU resources and eventually grinding Windows to a halt unless they are manually deleted in the Task Manager.

So is this some sort of a Wrapper-fault?

I am open to any more suggestions... ?


Though my tasks didn't abort, I did see something similar happen on my PC. I have an i5 2500k running windows 7 pro x64. There were 4 trp sv tasks running in boinc manager, yet 5 processes fighting each for a full core in task manager. Sure enough when i suspended BOINC, there was a sieve process using a full core. I killed that and then my tasks ran faster. that is the part that seems similar to yours, the process still using a full CPU core after it finishes in BOINC.



I have been having computation errors for a couple of days on 1 computer only. A check of task manager with BOINC suspended showed 2 tasks running that were not real. I ended the tasks and will see how it goes.

I have never had a similar error. It is a long while since I last ran TRP SV, the laptop is now turning on and off more often and I have set the "suspend while in use" flag. With so many changes and I do not know which has caused the error yet.

Like everyone else I have been catching up with SR5, now all BOINC available are Silver or better. Onwards to gold!!!

(Several years ago someone built a heavily overclocked desktop computer inside a cube fridge, essentially using the fridge as the computer case. If you google it, you'll get lots of hits.)



Many, many years ago (early 1980s?) I worked on the EMC testing of an Inmos multi processor device using about a dozen TRANSPUTERS. It was built in the alloy ice box from a fridge, with the cooling pipes still working and connected to the heat fins.

I redesigned the outer case to stop it wiping out half the radio spectrum and later presented a case study on it at Olympia in London. (No pun intended).

If that is what you were refering to then you have a good memory!!

Buy a Nissan Leaf.


Um?, do I connect 3 phase, 240 AC or 12VDC?

Posted 2711 days ago by Profile DaveBProject donor
Robocopy is great for moving big data around in memory, but once hardware limitations are met (such as measuring the time to actually load disk into machine, write it and take it out) there will be very little difference.

The key point here is that moving around memory can include moving into drive dedicated spaces which is faster so the CPU can get on with other things while the physical drive does its stuff.

Both the confused views above are therefore true, It depends on what you mean by time, time taken to fully complete the task or CPU time to do the task and leave the rest to peripherals.
