Re: Why the same code running on linux and windows differs so much (2X)

Well, Apart from driver's support, the underlying hardware also need to support VM.  ( i am sure of this)

Only when both are possible, VM is listed out there ( i believe so)

Re: Why the same code running on linux and windows differs so much (2X)

Just put some update of my effort to figure out what happen.

I have both kubuntu 12.10 and window 7 install on my laptop.

And my host code support offline compilation of the kernel code.

So I put the PTX binary code compiled under kubuntu to window 7 OS, and run my kernel using offline compilation which is compiled under kubuntu.

The performance is still 2 times slower than that of kubuntu.

So I suspect that it is the driver problem, as my driver under windows 7 is OEM specific and is not verified successfully by the AMD verification tool for the latest driver.

my platform is Samsung np530u3c ultrabook
