As someone suggested earlier, you dont need a full installation of gfortran 4.1. Instead search for a deb of libgfortran1, extract it into a folder and then include that folder in your library path.
Not sure where to ask and don't know if anyone have asked this question before. Can program using ACML-GPU run in virtual machine under VMWARE server?
I eventually made the acml-GPU examples work on my Linux machine. What a relief!
Acutally, some of the programs in the example folder are in infortran, so gfortran-4.1.2 is needed if one want to comple them. I downgraded my Ubuntu to 8.04 for whcih the gcc4.1.2 and gfortran-4.1.2 are both available and everything works.
What I really want to use are the FFT routines in the acml library. It looks like that they are not available for acml-GPU library yet. If it is true, do you know when they will be available? If possible I wish I can get some early vesions of them to test out. I will be happy to report the results back once I try them out. Mainly, I am interested in 1D FFT routines.
Thanks in advance for your help.
I recently wrote a program to benchmark NVidia's CUDA FFT (CUFFT) routine. The program did 204800 2048 point FFT and IFFT pair. It take about 17 seconds using a 9600GT. This is similar to the routines in FFTw Library on a 2.66 GHz Core 2 CPU. Very disappointed. Actually, AMCL scored the best. It only took 7 seconds. I also found independent verification from the Web that CUFFT only became faster if the FFT size is larger than 32768 points.
Hope AMCL-GPU FFT will be better when ready.
