LLRCUDA - getting it to work

diep · 2013-10-02, 00:54

hi!

Trying to get the Tesla's here going with LLR CUDA.

After some attempts got to work LLR CUDA at a box.
Didn't figure out yet how fast it is.
Seems to work for 3 * 2 ^ n - 1 here.

I'd like to test 69 * 2 ^ n - 1 with it.

Maybe i have the wrong syntax?

./llrCUDA -q"69*2^2410035" -d

Then it reports "Not support zero-padded rational base DWT"

What can i change to get it going?

Also not sure it was using the correct CUDA device when i tried some 3*2^n-1 exponents by hand as power consumption hardly got up when it ran as i have 2 CUDA devices in this machine. One 10 core card and one Tesla with 448 cores.

Help and user experiences with LLR cuda much appreciated!

Thanks,
Vincent

Hi,
69 is too large.
