Some Research Questions

ATI HD Radeon Card Question

Hello all,

I am in the process of doing some GPGPU research and need some questions about my GPU answered if possible.

I am running an ATI Mobility RADEON HD 4530/4570 card on a Dell Studio laptop using Catalyst 9.2. I was wondering if anyone has any information on the size of texture cache on this card?  Also, am I correct in assuming that if memory goes outside the defined bounds of on board memory the memory outside that bounds are mapped to main memory via PCIe?

One last question, does anyone know if there have been any successful implementations of CFD software using the GPU? I have found a few items on the iterative conjugate gradient solver but not its actual use inside of application code.  My quess is that many iterative applications like FEM are not good performers on GPU due to data element reuse?

Thank you.
