  • Generally, the basic optimization level -O2 or -O3 is selected.
  • -mcpu=tsv110 is used on a Kunpeng machine with microarchitecture affinity.
  • A high-performance math library is specified for HPC applications that have computing bottlenecks and involve frequent math library function invoking. For details, see Specifying Math Libraries.
  • jemalloc is enabled for the memory access bottleneck optimization. For details, see Specifying jemalloc.
  • LTO is enabled for the front-end bottleneck optimization, such as databases and distributed storage applications. For details, see LTO.
