  58  *
  59  * \param[out] fplog                 Open file pointer for log output
  60  * \param[in]  kernelBaseFilename    The name of the kernel source file to compile, e.g. "nbnxn_ocl_kernels.cl"
  61  * \param[in]  extraDefines          Preprocessor defines required by the calling code, e.g. for configuring the kernels
  62  * \param[in]  context               OpenCL context on the device to compile for
  63  * \param[in]  deviceId              OpenCL device id of the device to compile for

  67  *
  68  * \todo Consider whether we can parallelize the compilation of all
  69  * the kernels by compiling them in separate programs - but since the
  70  * resulting programs can't refer to each other, that might lead to
  71  * bloat of util code?
  72  *
  73  * \throws std::bad_alloc  if out of memory.
  74  *         FileIOError     if a file I/O error prevents returning a valid compiled program.
  75  *         InternalError   if an OpenCL API error prevents returning a valid compiled program. */
