  57  *
  58  * \param[out] fplog                 Open file pointer for log output
  59  * \param[in]  kernelBaseFilename    The name of the kernel source file to compile, e.g. "nbnxn_ocl_kernels.cl"
  60  * \param[in]  extraDefines          Preprocessor defines required by the calling code, e.g. for configuring the kernels
  61  * \param[in]  context               OpenCL context on the device to compile for
  62  * \param[in]  deviceId              OpenCL device id of the device to compile for
  63  * \param[in]  deviceVendorId        Enumerator of the device vendor to compile for
  64  *
  65  * \returns The compiled OpenCL program
  66  *
  67  * \todo Consider whether we can parallelize the compilation of all
  68  * the kernels by compiling them in separate programs - but since the
  69  * resulting programs can't refer to each other, that might lead to
  70  * bloat of util code?
  71  *
  72  * \throws std::bad_alloc  if out of memory.
  73  *         FileIOError     if a file I/O error prevents returning a valid compiled program.
  74  *         InternalError   if an OpenCL API error prevents returning a valid compiled program. */
