Spherical Harmonic Transforms (SHT) are at the heart of many scientific and practical applications ranging from climate modeling to cosmological observations. In many of these areas a new wave of exci...
We describe an algorithm for computing an inverse spherical harmonic transform suitable for graphic processing units (GPU). We use CUDA and base our implementation on a Fortran90 routine included in ...
