Python function

set_virtual_cpu_target

set_virtual_cpu_target()

max.driver.set_virtual_cpu_target(cpu: str) → None

source

Sets the CPU target for host-independent kernel codegen.

Set this before any CPU kernel is compiled. CPU kernels compiled afterwards target this CPU, so the kernel cache can be shipped to, and reused on, a host with a different CPU. Mirrors set_virtual_device_target_arch() for GPUs.

Parameters:

cpu – An LLVM target-CPU name, such as x86-64-v3 or neoverse-n1; generic, for the most portable baseline of the host architecture family (x86-64 on x86_64, the armv8-a baseline on AArch64, an error for other families); or an empty string, which restores host-CPU codegen. native is rejected because it would compile for the host’s CPU.
