Summary of Changes

This PR optimizes the threading logic in GESV by refining switchover thresholds for parallel execution, particularly for Windows on ARM64 (WoA).

  • COMPLEX Data type: Parallel execution if m * n > 600
  • SINGLE/DOUBLE Data type: Parallel execution if m * n > 1000
  • Ensures optimal threading on ARM-based devices.
  • Preserved existing thresholds for other platforms.

Benchmark Data (Timings in ms)

Below is the benchmark data comparing single-threaded vs. parallel execution for different input sizes on WoA.
