RGlimpse2 phasing-executable dispatch information

RGlimpse2 dispatches whole child executables rather than mutating a backend in the R process. The scalar SIMDe executable is always the fallback. A native executable is selected only when it was built and the package's baseline CPUID/HWCAP probe confirms CPU and operating-system support.

Usage

RGlimpse2SimdInfo(
  requested_backend = character(0),
  selected_backend = character(0),
  compiled_backends = character(0),
  cpu_supported_backends = character(0),
  available_backends = character(0),
  phase_executable = character(0),
  target_arch = character(0),
  target_os = character(0)
)

Arguments

requested_backend

Requested backend ("auto", "scalar", "avx2", "avx512", or "neon").

selected_backend

Resolved backend.

compiled_backends

Backends represented by installed executables.

cpu_supported_backends

Backends supported by the runtime CPU and OS.

available_backends

Intersection of compiled and CPU-supported backends.

phase_executable

Selected absolute executable path.

target_arch, target_os

Baseline probe target identifiers.
