Intel's Heterogeneous Core SIMD/AVX Roadmap and the Scheduling Problem

Research Report — February 2026 Audience: Senior kernel engineers (particularly RISC-V), for architectural comparison

---

Executive Summary

Intel's introduction of hybrid (big.LITTLE-style) x86 CPUs starting with Alder Lake in 2021 created an unprecedented problem in the x86 ecosystem: heterogeneous ISA support across cores within a single package. The P-cores (Golden Cove) supported AVX-512 while the E-cores (Gracemont) did not. Intel's handling of this — disabling AVX-512 across the entire chip — and their multi-year journey toward AVX10 as a solution provides critical lessons for any ISA designer considering heterogeneous core designs. This report covers the technical details, the OS scheduling implications, and comparisons with Arm, Apple, and RISC-V approaches.

How I Got Claude Code Working in China — What Works and What Doesn't

February 12, 2026

If you're a developer in China trying to use Claude Code, you've probably hit the 403 wall. This guide covers how to get it working in three scenarios:

1. macOS Terminal (shell) - using claude CLI directly in your terminal
2. VS Code Terminal - using claude CLI inside VS Code's integrated terminal
3. VS Code Claude Code Extension - using the Claude Code chat panel (installed as a VS Code extension)
