No Fortran main method exists, use C equivalent instead.

Enable use of SIMD directive inside of loop rather than on outer loop.
Enable use of SIMD directive inside of loop rather than on outer loop.
optimize for maximum speed and enable more aggressive optimizations that may not improve performance on some programs
Enable the compiler to generate multi-threaded code based on the OpenMP* directives (same as -fopenmp)
Enables OpenMP* offloading compilation for target pragmas. This
option only applies to Intel(R) MIC Architecture and Intel(R)
Graphics Technology. Enabled by default with -qopenmp.
Use -qno-openmp-offload to disable.
Specify kind to specify the default device for target pragmas
host - allow target code to run on host system while still doing
the outlining for offload
mic - specify Intel(R) MIC Architecture
gfx - specify Intel(R) Graphics Technology
Generate instructions for the highest instruction set and processor available on the compilation host machine.

Platform settings
One or more of the following settings may have been applied to the testbed. If so, the "Platform Notes" section of the report will say so; and you can read below to find out more about what these settings mean.
LD_LIBRARY_PATH=<directories> (linker)
LD_LIBRARY_PATH controls the search order for both the compile-time and run-time linkers. Usually, it can be defaulted; but testers may sometimes choose to explicitly set it (as documented in the notes in the submission), in order to ensure that the correct versions of libraries are picked up.
STACKSIZE=<n> (Unix)
Set the size of the stack (temporary storage area) for each slave thread of a multithreaded program.
ulimit -s <n> (Unix)
Sets the stack size to n kbytes, or "unlimited" to allow the stack size to grow without limit.
Flag description origin markings:
