It's been a busy couple of days on the GPU computing research front for me, sapping a lot of my spare GPU cycles.
yesterday, I helped a colleague with a GPU brute force MD5 password cracker....getting 1.2 billion checks per second, which totaly soaked up my 280s.
Then, I was working on a proprietary magnetic reconstruction algorithm on the GPUs that sped up the calculation over 200x from the CPU version.
Hopefully I can get back to putting the GPUs to good use (points!) today :)
Shait... didn't really know that tricking ref was a foul...Quote:

What Angra wrote he done today wasn't nothing compared how much I've spent work-hours to just extracting mucus from my nose... :D (j/k)
@Angra: What's the estimate your 280s can output in PPD at maximum? Just curious really :)
Password cracking :poke: :rofl:Quote:

asci is only 255 chars ( 255 ) ^ 8 = 1,1865504027970838771731346061683e+616 options?
there's only ~95 realistically useable characters for passwords, though. (95^8 items)/(1.2e+9 items/second) = about 70 days.
Yeah extended chars are to be excluded :am: :rofl:
You're our mad scientist for a reason :up:
Edit: though I wonder how long it will take me on my cpu, that 1.2e+9 items a second seems rather slowish??
yes, but you know how the IT guys want you to use some special characters....
boy i can remember when most passwords were just 3 characters... god
now where is that funny story i found about passwords ?? anyone remember it,
it started out with 3 characters
then went to mininum om 5
then no names
and it kept going on for like a half of a page...
and the last one was so difficult to type and remeber, everyone in the office just wrote it down on a stickey pad and taped it to the monitor :)
I've got dual- 9800 GX2s on 3 rigs. :) 2 are on a Maximus Rampage, 2 on a P5Q Pro and the most recent edition was my old ICFX3200T2R/G that was sitting in the closet.Quote:

Those errors were usually "missing cudart .dll" or similar and could be resolved by copying the correct .dll from the F@H program Files/ Program Files (x86) folder to the correct gpu2 Application Data or Roaming folder. :)
oooh, good call. I remember getting that error when I started too.Quote:

yup, thats the one, thanks wfo ill try that when i get home :)
Skycrane, you are dangerously close to a "slacking penalty". Better get the rig sorted quickly.
Mike: Thanks for calling my Boss today & telling him I had to leave immediately due to a family emergency. When I got home I did find one of the Stoli's bottle near empty. I switched over to Absolute
Angra, You are hereby issued a PhD from dak Institute of Crackology
sc00p, now you are aware that tricking dak is a penalty, so watch it...
Who had the snots? I don't remeber...Time for dak to load up some Absolute,.
can't u just upload some absolut, im thirsty...
+ 10,000 pts to sniperbob for thinking big + outside the box.:clap::clap::clap:
Another SMP client just added for Foxtrot. It's 17:00 somewhere so it must be 0:beer:30 now. :p:
Overclockers Club is going down in the next 24hrs. Hopefully that will give Coo-coo time to prepare the battle report. :yepp: And btw, TOP 30 when we do guys!!! :YIPPIE::bounces::guitar::party::toast::toast2:
:eek2: :wtf:
Sorry coo-coo, after the last update we overtake in 9.4 hours. Write quickly!:rofl:
im working on getting my rigs up and running... hopefuly soon :)
if not, anyone near DC that wants to take a road trip?? ill buy a bottle of whatever you like....
WTF is Milkyway@Home...a candybar?
Milkyway@home? What am I missing? Who edited their post so I can't have a laugh here :soap:
Skycrane I don't life that far, just buy me a ticket :yepp: Ow and one for the kid and missus as well.
New weapon deployed tonight... modest, but still hopefully good for another 3-5k or so...
:up::up::up::worship::worship:Quote:

Actually I can debug people's errors with logs this way.
Edit: yeah I got someone else dumping points on me in trade for a cpu to wcg, idk what happend the last 2 monts though as my output has dropped allot ( had about 150K a month on the nicer gpu2 wu's now I was dropping below 100K )
It wasn't successful evening on my place yesterday :(
First I was going to just swap few rams on my pc. Result was that I damaged my gfxcard, small cap went off, oops (it was 8800GTS so nothing special though).
OK... went to shopping and bought 9800GTX+. Yeah anyone who knows my design of a pc-cube knows that swapping a gpu card takes about 2 hours. Yeah :rolleyes:
Spent some more time doing preparations for this surgery... only to find out bracket meant for G80 of course do not fit on G92 (Swiftech MCW60 block)...
...so :banana::banana::banana::banana: happens.
And I can't find right now the proper flange for G92+ anywhere, figures...
I would have a folding box with a 8800GT too with mysterious black out... waits for troubleshooting also :D
Few beers didn't help anything... dak: should I move to proper liquids ?
Now 8800GT, 8800GTS, 9800GTX+ (and q6600) produces zilch...
Damn, I blew a gasket on one rig. I new that old Antec PSU wasnt going to make it running 2 9600s... :shakes: I will get another in the morning...:up:
Hopefully that is all that went. My experience is the PSU likes to take something with it. :(Quote:
