Program Model Specific Options

-h [no]acc

Default: -h acc

Enables or disables compiler recognition of OpenACC pragmas.

-h mpin

Default: mpi0

Enables or disables optimization of MPI operations. mpi1 enables this option.

-h [no]omp

Default: -h omp if -O1 or higher is implied or specified.

Enables or disables compiler recognition of OpenMP pragmas. If -O0 is specified, then -h noomp is implied.

-h upc (cc only)

Default: off

Enables compilation of Unified Parallel C (UPC) code. UPC is a C language extension for parallel program development that allows you to explicitly specify parallel programming through language syntax rather than through library functions such as are used in MPI or SHMEM.

-h upc is not supported in the Envoy environment.
