CPU ISA Hints
Supported values (defaults in bold)
Enables CPU ISA hints
Use default configuration for ISA Prefer to use YMM registers for vector operations
- dnnl::set_cpu_isa_hints function allows changing the CPU ISA hint at run-time. The limitation is that it is possible to set the value only once. In addition, it is advised to call this function before any other oneDNN API. This is because the first internal query of CPU ISA hints will disable the ability to change it. Once disabled, changing the CPU ISA hint will return an error.
