Convert fortran function to Cuda

hi there, your CUDA conversion seems pretty interesting challenge for me, however not being a fortran coder I can simply try to understand the initial code. It seems like it depends on Math libraries for solving equations, correct? My estimation is that these libraries would probably make the CUDA conversion task pretty cumbersome!

Hello, I have 5 years of experience working in fortran software development, and 1 year in cuda. From what I saw in your code I'm qualified for do it. But I'm not really sure about how much time you could save from writting this function in CUDA. The time that you can save from vector operations, such as adds and assigments, is really small in comparation to the time of fop%op (If is it not parallelized). So, my advice is, you should keep in mind migrate the fop%op to CUDA. Another point is that there are two diferents ways to migrate this function to CUDA. The first, the easiest and the one that I recommend you is write these subroutines in C and launch the CUDA kernels from it. The second is using CUDA Fortran with the PGI compiler. Install the PGI compiler will take you time, effort and troubleshooting. And you need to ask for a license. If you are interested in my services, write me, so we can talk more about what would be the best solution for your needs. Best regards, Ricardo

Hi, I may be new on freelancer but I have my hands on developing high performance computing solutions, and have in CUDA, OMP, MPI based data parallel application development for GPUs, Multicore CPUs, Xeon PHIs, using libraries such as Intel-mkl, CuBlas, CuFFT.
