    i wonder how the back-end systems are configured. one would guess the instance you pay for is not a VM since you cannot access the GPU directly, unless Amazon figured out a way.

    I believe it's kVM from what I've read. You get 2 Tesla cores, which unfortunately, only crack at about 49k PMK/s. It's too bad they didn't use Radeon 6990s. :P Those would get 280k PM/s and cost less.

    Yes, if you want speed over reliability. I personally would not want my cracker to miss cracking the password/hash, which in my eyes is a failure.

    I have a hard time believing the accuracy of those numbers. Benchmarks are almost always higher than the actual.

    Here's a few posts to sink your teeth into:

    I do pretty well with my Nvidia GTX 480 (Fermi) at 180K KP/S. Unfortunatley not 64bit until BT5 so kinda limited in terms of tables.

    I could probably take the time to set it up as 64bit manually but im just too lazy.

    http://it.slashdot.org/story/10/11/1...-GPU-Instances
    "As of Nov. 15, 2010, Amazon EC2 is providing what they call 'Cluster GPU Instances': An instance in the Amazon cloud that provides you with the power of two NVIDIA Tesla 'Fermi' M2050 GPUs... Using the CUDA-Multiforce, I was able to crack all hashes from this file with a password length from 1-6 in only 49 Minutes (1 hour costs $2.10 by the way.). This is just another demonstration of the weakness of SHA1 — you really don't want to use it anymore."

    I'm a compulsive post editor, you might wanna wait until my post has been online for 5-10 mins before quoting it as it will likely change.

    I know I seem harsh in some of my replies. SORRY! But if you're doing something illegal or posting something that seems to be obvious BS I'm going to call you on it.
