GPULib 1.8 released

GPULib 1.8 has been released with updates to the underlying libraries as well as many other features in many areas of the library. It has been updated to use the most recent versions of IDL and CUDA, IDL 8.4 and CUDA 6.5. The new features are:

  • Support for integer data types. I have been wanting to support integer types in GPULib for awhile and now GPULib supports all the numeric types provided by IDL! We can finally do:

    dx = gpuIndgen(10)
  • Added GPUREPMAT routine. This is a handy routine to create a new array by repeating a 2-dimensional array in a grid.

  • Added GPUCREATEKERNEL routine to create the source code of a simple kernel. This is a code generation routine that can be loaded with GPULOADMODULE/GPULOADFUNCTION and executed with GPUEXECUTEFUNCTION.

  • Added GPUFINITE routine similar to IDL's library routine.

  • Added linear algebra routines GPULUDC, GPULUSOL, and GPULEAST_SQUARES. This fills out more of the GPU equivalent of the convenience routines provided by IDL so that the LAPACK interface of MAGMA is not required to perform linear algebra computations.

  • Added support for RHO and THETA keywords in GPURADON.

  • Added GPUMEAN routine. This routine has DIMENSION and NAN keywords with the same functionality as IDL's library routine.
