I am a newbie to CUDA and am still trying to get my head around this whole new desktop supercomputing revolution!
I would like to try and use CUDA to do some simulations and of course, using floating point arithmetic there is not enough.
Is double precision arithmetic available on all CUDA hardware or do you need to have the latest and greatest cards for that to work? I have a 8600M GT on my laptop and I am guessing I could not expect double precision arithmetic on that.
Also, are there some limitations on how many double precision variables I can have or something… Of course the number of register variables must be limited but are there any other limitations on declaring variables with double precision?
Hope for some answers.
