- Vector instruction set usage (AVX-512)
- Cache hierarchy and memory bandwidth management
- FPGA interfacing and acceleration patterns
- Power management APIs (TDP controls)
Getting Started
- Install Intel oneAPI DPC++ compiler
- Leverage
offload pragma
- Profile with VTune Amplifier
Key Hardware Concepts
Intel Core Architecture
Understand the Intel core design principles including instruction pipelining, out-of-order execution, and branch prediction algorithms.
Cache Hierarchy
Optimize applications by understanding L1-L3 cache latency and capacity characteristics.
SIMD Acceleration
Utilize Advanced Vector Extensions for parallel computations using Intel Intrinsics and DPC++.
Thermal Management
Understand Intel's power delivery and thermal design to build reliable systems.
Code Optimization Examples
#include <immintrin.h> void matrix_mult(float *A, float *B, float *C) { __m256 row_a = _mm256_load_ps(A); __m256 row_b = _mm256_load_ps(B); __m256 result = _mm256_dp_ps(row_a, row_b, 0x33); _mm256_store_ps(C, result); }
This AVX-256 example demonstrates vectorized matrix multiplication. Use _mm256_permute_ps
for operand alignment optimization.
