public static String preparePtxFile(InputStream cuFileStream,
                                    String arch)
                             throws IOException,

The extension of the given file name is replaced with "ptx". If the file with the resulting name does not exist, it is compiled from the given file using NVCC. The name of the PTX file is returned.

Parameters:

cuFileStream - The name of the .cu file

arch - String specifying the architecture (see nvcc command, -arch argument). Examples are sm_12, sm_20, sm_30

Returns:

The name of the PTX file.

Throws:

IOException - Thrown if an I/O error occurs.

URISyntaxException - Thrown if the cuFileURL cannot be converted to an URI.
