Compilers: AMD Fortran/C/C++

Operating systems: Linux

]]>

The OpenMPI C++ driver configured for use with the AOMP C++ compiler (clang++).

]]> mpic++ The OpenMPI C driver configured for use with the AOMP C compiler (clang).

]]> mpicc The OpenMPI Fortran driver configured for use with the AOMP Fortran compiler (flang).

]]> mpif90 Disable warning messages.

]]> -w A basic block is generated for each C statement. No scheduling is done between statements. No global optimizations are performed.

]]> -O0 Level-one optimization specifies local optimization (-O1). ]]> -O1 Level-two optimization (-O2 or -O) specifies global optimization. ]]> -O2 All level 1 and 2 optimizations are performed. In addition, this level enables more aggressive code hoisting and scalar replacement optimizations that may or may not be profitable.

]]> -O3 All level 1 and 2 and 3 optimizations are performed. In addition, this level enables more aggressive code hoisting and scalar replacement optimizations that may or may not be profitable.

]]> -O3 Generate output files in LLVM formats suitable for link time optimization.

]]> -O3 Enable OpenMP compilation for hpc2021.

]]> Enable OPENMP programming model for hpc2021.

]]> Enable OPENMP Target Offload programming model for hpc2021.

]]> Enable using textual F90 include instead of modules for MPI in hpc2021.

]]> Select target to compile for.

]]> -targets=amdgcn-amd-amdhsa Select the openmp target to compile for.

]]> -Xopenmp-target=amdgcn-amd-amdhsa Select the specific target architecture to compile for.

]]> -march=gfx900 Select the specific target architecture to compile for.

]]> -mcpu=x86
