1) Message boards : Number crunching : Host with WAY too many tasks. (Message 45662) Posted 21 Jan 2011 by Vid Vidmar* Post: This issue has been escalated and is being worked on as I type this note. Thank you for the information. Hi Blurf, I know, OT, but nevertheless could you please also escalate issue of too old server build that makes impossible to set MW as backup project (ie. resource share of 0 is still invalid here)? Thank you. BR
2) Message boards : Number crunching : Need to quit (Message 45017) Posted 15 Dec 2010 by Vid Vidmar* Post: Did you attach through AMS (like BAM)? In that case, you need to detach the project there and not in local boinc manager. BR
3) Message boards : Number crunching : Need to quit (Message 44955) Posted 12 Dec 2010 by Vid Vidmar* Post: Hi Can someone tell me how to quit from this project. Thanks Kamal Abort all wus, update the project and when all reported, click detach. But, stop work fetch first.
4) Message boards : Number crunching : GPU disabled when I connect to machine remotely (Message 42117) Posted 14 Sep 2010 by Vid Vidmar* Post: These other remote access gateways at least give you the potential to give you the remote PC monitoring without the loss of GPU crunching. I was unsure whether these existed, so at least there is a potential solution. For me, it's actual. The only difference between actual and potential solution is whether you try it or not. :) Cheers!
5) Message boards : Number crunching : GPU disabled when I connect to machine remotely (Message 42110) Posted 14 Sep 2010 by Vid Vidmar* Post: In windows, remote desktop (when active) replaces loaded graphics drivers with some M$'s virtual drivers, and thus effectively disabling all GPU computation abilities. The only known solution is to use other RD/VNC software that doesn't touch the graphics drivers. I use TightVNC. BR,
6) Message boards : Number crunching : Wow! CPU WUs done in just 160 secs! (Message 41967) Posted 7 Sep 2010 by Vid Vidmar* Post: I think this is a SP app build in action (again!). I was hoping that these were already banned. Unfortunately it doesn't seem so. BR,
7) Message boards : Number crunching : Wu Size (Message 41003) Posted 20 Jul 2010 by Vid Vidmar* Post: That's why some of us use app_info.xml files to get 2 WUs running concurrently on single GPU. If their start time is offset by more than 2s then there is no dip in GPU activity. BR,
8) Message boards : News : New Website Coming Soon (Message 40587) Posted 23 Jun 2010 by Vid Vidmar* Post: In css add this line: a img { border: none; } Otherwise, nice, gray.
9) Message boards : MilkyWay@home Science : Is it posible that the universe are colapsing at this very moment? (Message 40474) Posted 17 Jun 2010 by Vid Vidmar* Post: Thanks for making my point Vid. Most appreciated. How can you know where the universe is going, if you don't know where it's been? The 'point' or 'singularity' of the big bang, well, it came from somewhere. Yes, if you take my statement generally, however in context of debate over the beginning of universe (which I got impression this thread was turning to) here and now could also be a place for theology. I will admit (and I in no sense believe in God in any traditional way; I am not religious), that the beginning of universe may be the sole act of God, God's will if you like. One more thing all this reminded me of, and it is also connected to cosmology, beginning of universe and even more mundane everyday things is time. One day, couple of years ago, I had a talk with a family friend, a professor of mathematics, about how I came to conclusion that time is probably running in discrete intervals rather than continuously. My reasoning was the following: After the big bang, up to a certain time things are not only undefined, but also undefinable (at the moment). That is called planck's time. Therefore if time ran continuously, it would be no problem to "calculate" the state of universe down to arbitrarily short time interval, even to the beginning itself. To my amazement, he agreed. And just now, when I checked if I spelt "planck" right, I noticed, that some more established scientists think likewise (wow! :D ). Nevertheless I would also be interested in others views. Are we ticking or running smooth? BR

(Message 40469) Posted 17 Jun 2010 by Vid Vidmar* Post: And the fish in the water swims around casually believing water is the only world there is. Just keep swimming. That's all very well to have your own opinion. As all the mathematicians must be playing a fun game with M-theory. Seems like an awful lot of funding for a mathematical game, wouldn't you say? Last i saw experimental/observational evidence for that was zero, nada, zilch, zip. Let's get some membranes out, and make a loaf universe!! And if Wiki is your source of info, please find a more serious, scientific one. The people who correct/quote/contribute are all on board with mainstream science and have little time for others who wish to challenge their view. Wiki = popular opinion, not fact. The philosophy you are invoking is the God theory i believe. In the beginning..... springing out of nothingness into something. Something from nothing. A 'point' that sprang from nothingness to something, within nothing. Spontaeneous creation. Mr Physik, theology doesn't belong here. On the contrary... I think that only place(and time) left for theology in our universe is at it's beginning. From there on, it's pure science. BR
11) Message boards : MilkyWay@home Science : Is it posible that the universe are colapsing at this very moment? (Message 40461) Posted 17 Jun 2010 by Vid Vidmar* Post: It's also possible that what lies outside our universe may push back on the universe one day, condensing it. Or what encompasses our universe may actually be sucking it out. To me a question of what is "outside" our universe is more philosophical than scientific. I strongly advocate idea, that "outside" our universe shouldn't even exist. Only that way all the "space" our universe needs is "provided". To explain this concept I usually use sets. I define our universe as universal set (convenient isn't it? :) ) then I ask what is "outside" of a set? A complement of a set of course, and a complement of universal set is an empty set. Voila! Yet again, this is my personal belief and should not be treated as scientific fact until proven. BR
12) Message boards : MilkyWay@home Science : Is it posible that the universe are colapsing at this very moment? (Message 40460) Posted 17 Jun 2010 by Vid Vidmar* Post: Going back to the original question of the thread. Is it possible that the universe are collapsing at this very moment but wee are unable to se it? We may see the full extent quite a bit later, but the relative velocities of nearby objects are so small that we would see it there first. It can't hide. If all the stars & galaxies emerged from an non rotating point in universe I expect that they would fly outwards but that the gravity will gradually slow down the velocity of everything so they will eventually stop and than start to accelerate back to the origin of the staring point. If the universe will stop (or even reverse) its current expansion depends crucially on the density of the universe. If there isn't enough matter in here (exerting gravitational forces), the expension will never stop. The visible (known) matter in the universe accounts for less than 2% of the needed "critical density". Even when considering the dark matter evident from the measurement of the rotation of galaxies and their movements in the galaxy clusters, we have only about a fourth of the needed mass. And there is still the issue of the so called Dark Energy (pushing the universe apart). Current observations may hint to quite a bit of it (more than 70% of the total mass/energy in the universe is currently supposed to be dark energy), which leads to an accelarated expansion and not a slowdown. But frankly, I don't buy into that yet (but this is my personal opinion not based on anything I would call a sound reasoning, it's more a feeling, I simply don't like it ;). I read somewhere, that by recent long-term CMB observations and measurements, it has been concluded that after all our universe seems to be flat instead of open. So it might be that your (and mine) feeling might not be far off. My reasoning in support of non-open universe goes somewhat along this line: the further out we look, we see further back in time. And we see redshift. To me that redshift means nothing more than a fact that things we observe moved at such speeds relative to us at THAT time, not NOW. And since doppler effect (blue/redshift) is a function of speed, is as such invariant to distance, so, if our universe was indeed accelerating in expansion, we should see a lot more redshift closer to us than further out. And not wanting to become a victim of Dunning–Kruger effect, I am fully aware that my knowledge in this area is far from perfect, I just wanted to present my line thinking about this question. BR
13) Message boards : Number crunching : Simultaneously CPU & GPU (Message 40436) Posted 16 Jun 2010 by Vid Vidmar* Post: For GPU app. I specify b-1 command line option, which enables aggressive GPU polling, resulting in 90%+ GPU usage and perhaps 2% CPU (for polling). So, there is absolutely no significant loss. Even now, with MW @ 1/4 GPU RS and DNETC @ 3/4 GPU RS I get a RAC of 75k+ here and 275k+ over there. That's a RAC of 350k+ on this machine with a 4870 and a 5870 in it. BR
14) Message boards : Number crunching : Simultaneously CPU & GPU (Message 40414) Posted 15 Jun 2010 by Vid Vidmar* Post: My host isn't hidden.. ;-) I use the latest recommended BOINC V6.10.56 . Only to understand well. You have also an app_info.xml file with both entries (CPU & GPU). You have checked CPU & GPU in your project preferences. Your PC got MilkyWay CPU WUs in past? ... That is correct. With that app_info.xml I run both CPU and GPU apps successfuly ever since I posted it here on these boards (did I mention that with it I run 2 WUs on each GPU at once?). But once again I must admit that I didn't try running MW solo with it. Hope, you get it sorted out soon. BR [edit] TGG luckily, you are wrong. ;) [/edit]
15) Message boards : Number crunching : Simultaneously CPU & GPU (Message 40398) Posted 15 Jun 2010 by Vid Vidmar* Post: Hm, no, I haven't seen anything like that on my cpu/gpu mixed cruncher, however that box also crunches PrimeGrid and thus always has cpu work at hand. Which BOINC version are you running BTW? BR,

17) Message boards : Number crunching : How can I run two WU's concurrently? (Message 39574) Posted 10 May 2010 by Vid Vidmar* Post: ... and if the count command is 0.5 to get 1 gpu to get it to use crunch 2 work units back to back what on earth do you insert to have 3 gpu's doing 6 wu back to back ? or will it still be 0.5 and it will split them all itself into 2 each per gpu ? best regards Ian With 3 GPUs you will be doing 6WUs concurrently with <count>0.5</count> setting. (but isn't 4890 a 2GPUs card? With 3 of them in one box it should run 12WUs with that setting). BR
18) Message boards : Number crunching : Nvidia + ATI (Message 39340) Posted 1 May 2010 by Vid Vidmar* Post: Hello is it possible to run a GTX260 and a ATI5800 in one pc? How can i manage the 2 different drivers for windows and games? Yes on XP and win7 (I think), it is possible. A good year ago I ran 8800GT and 4870HD under XP 64 without a problem. Just installed drivers for both cards, and that was it. BR,
19) Message boards : Number crunching : Multiple GPU's (Message 39133) Posted 25 Apr 2010 by Vid Vidmar* Post: ... If you can run without the flag, well, you better man than I ... :) After he put in that code, I have dropped that line in my cc_config and don't leave home without it ... who knows what whim will take DA next ... Just luckier, I guess, as luck has a lot more to play in BOINC world than "goodness". :D (I consider myself very lucky, after successfully persuading BOINC to run MW on both GPUs and CPU using opti apps via app_info.xml). On that last observation... I wouldn't dare to start imagining what surprises might there be in store for us.. :^) BR
20) Message boards : Number crunching : Multiple GPU's (Message 39125) Posted 25 Apr 2010 by Vid Vidmar* Post: However, you do have to make sure that BOINC "sees" both and uses both ... most of us have to use the flag in cc config because DA invented a cleaver idea and will not remove it ... bottom line, if there is a difference in the cards in BOINC's opinion it will only use one of the two ... <use_all_gpus>1</use_all_gpus> in the "options" section of the config file, stop and restart BOINC. No such flag used here, BOINC 6.10.32, ATI 4870 & 5870 both crunching @ 100% with (and without on some other projects) app_info.xml (lookie). Again, are things that much different in CUDA world? BR,
