still no LLR_Out for linux. :(
2) Message boards : News : Pls disable Sierpinski / Riesel Base app (base S712) (fixed) (Message 876)
Posted 9 Feb 2015 by frankhagen
I have found a small mistake in relation of the S712 base in a script that caused the empty input files. I have cancelled all WUs and will recreate new until the rest of the WUs are returned.

The more modern the AMD architecture -the more (theoretically) complete the possible instruction set-, the worse the performance???


plain simple?

yes - if you call for floating-point performance.

integer speed is just another thing.


and about "K10-baesd" - those things lack that big L3-cache - pretty ugly....

Ever watched in the debugger whether an AMD CPU actually uses the AVX part of the code? the Intel compiler-made Assembly seeks a when running on a non-Intel CPU.



oh no - not again that ancient story. :(

even if this still would be the case - but of course you seem to be sure that intels compiler has been used for the app in use here...
7) Message boards : Number crunching : Checkpointing? (Message 768)
Posted 26 Jan 2015 by frankhagen
To avoid losing work due to task switches, you can set the flag "Leave applications in memory while suspended".

These apps use very little memory and will continue where they left off, even with no checkpoint.


i really doubt that this will work here. you either prevent boinc from switching tasks or stick to the short queues.

now it's definitely wrong for each and everyone.

well done.


It will only take 1-2 days to catch up.


this would be a totally new definition of RAC.

VFP10 is a step in the right direction. When that's available, serious discussion about ARM versions of this software will be reasonable. It will still be slower (and a lot slower), but not nearly as bad as the current differential of several orders of magnitude.

Until then, we wait patiently.


if anyone is going to buy that design and goes into mass-production.
does anyone need a gadget capable of running vector math?

Did I anywhere said "current ARM CPU" in my message?


of course you can keep on trying to earn an *****-badge, but this is boring.

The max success results is 50% working. The task is getting a success but getting no credits. I need to find out whats wrong.


about half of them as far as i can see.

rocket-science - you know. ;)

well, i did not want to give them a five figures penalty on this, but you are right, it would end up somewhere around that.

not even thinking of PI's...

the next one showing up with this suggenstion might earn one of my spare slide rulers. ;)

Posted 3 Jan 2015 by frankhagen
You haven't come close to explaining why a short deadline is needed.


plain simple: only after the last wu of a batch has been returned, the results can and have to be evaluated manually.

after that the next batch can be prepared and started.

not that hard to understand - isn't it?

This is a shame, because I keep my laptop loaded with BU tasks, normally, but have 2 or 3 ARM devices that are crunching for other projects, but I would love to donate more power to this project, but can't for now - once the project gets famous and grows, could there be an ARM app - it would get 1000s and 1000s more devices involved...


OMFG!


could you please consider that this projects needs IEEE 754 compatible FLOATING-POINT hardware and there is no ARM design available providing this?

software emulation could be coded (if anyone would be crazy enough) but you'd have a penalty in speed of at least 2 magnitudes.

so can we please have a note on the main page, that this is not going to happen?

this is bullcrap!


every "sub-project" is SR5 - really no need for seperate extra badges...
