Any benchmark for CHOLMOD on GPU

Hi,
I need this information regarding a funding proposal I am resubmitting.
I have been asked to justify proposed purchase of GPU and report some benchmark against CPU for my application. Most time consuming part of my algorithm involving sparse matrix is CHOLMOD. I am planning to use the one on Prof. Tim Davis' website which is already optimized for GPU:
Any benchmark for either his CHOLMOD algorithm or any CHOLMOD algorithm would be appreciated.
I am expecting my sparse matrix size to be 7000 x 11000.
IF no benchmark can be suggested, can someone suggest me how should I convince reviewers by doing back-of-the-paper calculation.
Regards, DK

I am also interested in this.
I am currently trying to build Cholmod with GPU under Linux
There is no support in Cholmod for GPU support with the example Mex files created in the cholmod/matlab folder

For your matrix size, you are unlikely to see much benefit, though
