Performance Analysis for Applications & Systems

Intel® VTune™ Profiler optimizes application performance, system performance, and system configuration for AI, HPC, cloud, IoT, media, storage, and more.

• CPU, GPU, and NPU: Tune the entire application’s performance―not just the accelerated portion.
• Multilingual: Profile SYCL*, C, C++, C#, Fortran, OpenCL™ code, Python*, Google Go* programming language, Java*, .NET, Assembly, or any combination of languages.
• System or Application: Get coarse-grained system data for an extended period or detailed results mapped to source code.
• Power: Optimize performance while avoiding power- and thermal-related throttling.

Features

• Algorithm Optimization - Locate hot spots—the most time-consuming parts of your code. - Visualize hot code paths and time spent in each function and with its callees with Flame Graph.
• Microarchitecture and Memory Bottlenecks - Identify the most significant hardware issues that affect the performance of your application with microarchitecture exploration analysis. - Pinpoint memory-access-related issues such as cache misses and high-bandwidth problems.
• Accelerators and XPUs - Optimize GPU offload schema and data transfers for SYCL, OpenCL code, Microsoft DirectX*, or OpenMP* offload code. Identify the most time-consuming GPU kernels for further optimization. - Analyze GPU-bound code for performance bottlenecks caused by microarchitectural constraints or inefficient kernel algorithms. - Understand how much data is transferred between a neural processing unit (NPU) and DDR memory and identify the most time-consuming tasks running on the NPU.
