NVC/NVC++/NVFORTRAN Compilation Parameter Optimization

Table 1 lists the NVC/NVC++/NVFORTRAN compilation parameters, which can be added during compilation for optimization.

**Table 1** NVC/NVC++/NVFORTRAN compilation parameters
Compilation Option	Description
-Mcache_align	Indicates cache alignment by byte.
-Mfpapprox	Uses low-precision approximation to perform operations such as division and square root.
-Mautoinline	Configures parameters for automatic inlining.
-Minline	Inlines simple functions that are called multiple times.
-Mipa	Performs process analysis and optimization.
-Munroll	Controls loop unrolling.
-fast	Enables vectorization, cache alignment, and flushz.
-gpu=fastmath	Specifies the GPU option to use the fast math library.
-gpu=flushz	Specifies the GPU option to enable flushz.
-O 0 1 2 3 4	Indicates the code optimization level. O4 is recommended.
