Tuning Recipes
These recipes explore typical application performance problems that you can detect with Intel® VTune™ Profiler or its predecessor, Intel® VTune™ Amplifier. Use the guidance in these recipes to optimize performance.
- Cache-Related Latency Issues in Segmented Cache Environment
This recipe demonstrates how to use Cache Allocation Technology (CAT) to handle cache-related latency issues (cache misses) when you split a cache between cores. - False Sharing
This recipe explores profiling a memory-bound linear_regression application using the General Exploration and Memory Access analyses of the Intel® VTune™ Amplifier. - Frequent DRAM Accesses
This recipe explores profiling a memory-bound matrix application using the Microarchitecture Exploration and Memory Access analyses of the Intel® VTune™ Profiler to understand the cause of the frequent DRAM accesses. - Poor Port Utilization
Profile a core-bound matrix application using the Microarchitecture Exploration analysis in Intel® VTune™ Profiler. Understand the cause for poor port utilization and use Intel® Advisor to benefit from compiler vectorization. - Page Faults
Identify and measure the impact of page faults on application performance. Use Microarchitecture Exploration, System Overview, and Memory Consumption analyses in Intel® VTune™ Profiler. - Instruction Cache Misses
Profile an application bound on the front-end and reduce ICache misses using the Microarchitecture Exploration analysis with the PGO option. - OS Thread Migration
Identify OS thread migration on the NUMA architecture with the Hotspots analysis in Intel® VTune™ Profiler. - OpenMP* Imbalance and Scheduling Overhead
Follow this recipe to detect and fix frequent parallel bottlenecks of OpenMP programs, such as imbalance on barriers and scheduling overhead. - Processor Cores Underutilization: OpenMP* Serial Time
Use this recipe to identify a fraction of serial execution in an application that was parallelized with OpenMP. Discover additional opportunities for parallelization, and improve the scalability of the application. - Scheduling Overhead in an Intel® oneAPI Threading Building Blocks Application
Detect and fix scheduling overhead in an Intel® oneAPI Threading Building Blocks (oneTBB) application. - PMDK Application Overhead
Find and fix an overhead on memory accesses for a PMDK-based application.
