OpenCL plans & details

[Bitweasil]

Update:

Found a major bug in how I'm handing odd password lengths, to the point that odd password lengths are being done "totally wrong."

I need to fix this before I throw out a beta...

Further update:

I'm an idiot.

Before copying a small number of bytes into a uint64_t pointer, one may wish to set the memory at the pointer to zero first.

Values hanging out in the high order bytes you aren't copying into matter. A LOT.

The good news: My generate code is actually solid. Awesome.
The annoying news: I just spent 90 minutes tracking down a bug in my "table verify" code due to not having the memset in place. GRAGH.

Better than the few hours I spent trying to figure out weird data corruption when opening binary files in Windows with the "r" or "w" flags instead of "rb" or "wb"...

Anyway, I'm more confident in my code integrity now, and that it's doing the correct thing, so as soon as I finish adding NTLM support to the OpenCL cracking tools and verifying those, I should be ready to throw out a beta. It's less useful with MD5 only right now... NTLM is half done.

Hi Bitweasil

updated my computer:

Now,

1x HD5770
2x HD6970 (only 1 in the computer, because I#m not sure with the power supply)
2x HD6990 (only 1 in the computer, because I#m not sure with the power supply)

I hope your OpenCL version will support all my cards, maybe I can help you with the HD6990 support

Another question, is a 1250W OCZ ZX series power supply enough or not ?

108 + 250 * 2 + 375 * 2 = 1,358 so definitely no.

Thx for your explaination Sc00bz,

So for a 1000W power supply this config would be okay: 3x250W(6970) + 1x108W(5770) = 858W ?

So if I want to use the other config I need 1358W. Can I connect a 1000W- with a 750W power supply? And if this is possible how to connect these two power supplies?

I heard that the HD6990 needs up to 567W: "http://www.computerbase.de/artikel/grafikkarten/2011/test-amd-radeon-hd-6990/25/". When this is correct your explaination would be wrong

Get something like whats shown in the link.

Allows you to chain up ur PSUs and trigger start them up together.

You need to account for powering CPU, motherboard, memory, and hard drives. Also you should leave some room so the power supply is not running at 100% all the time.

You missed the part in red at the top of http://www.computerbase.de/artikel/graf ... d-6990/25/ "Gemessen wird die Gesamt-Leistungsaufnahme des Testsystems." and translated "Measures the total power consumption of the test system."

I got the power consumptions from http://en.wikipedia.org/wiki/Comparison ... sing_units

Thank you Sc00bz, my mistake.

There are certain power supplies rated for "continuous power" output - those are theoretically good for rated power at 100% of the time.

In general, though, 80% is a good cap.
