Get Started with Profiling

Matrix Multiply for Heterogeneous Applications

Learn how to profile a code that's compliant with SYCL* for CPU and GPU using Intel® VTune™ Profiler. The sample contains three implementations of matrix multiplication using different SYCL features.

Matrix Multiply for C Code Running on a CPU

Learn how to use Intel VTune Profiler to profile C code running on a GPU. Six different implementations with various levels of CPU optimizations are included.

Guided ISO3DFD OpenMP* Offload

This sample exposes some typical challenges you face when offloading applications onto OpenMP* offload devices and introduces techniques to resolve them.

Tachyon for Optimizing OpenMP or oneTBB Applications

Learn how to use Intel VTune Profiler to improve performance of parallelized applications using OpenMP or Intel® oneAPI Threading Building Blocks (oneTBB) running on a CPU.


Application Profiling Tutorials

Analyze Hot Code Paths Using Flame Graphs​

Understand how you can use Flame Graphs to detect hot spots and hot code paths in Java* workloads using a sample application.​

Profile MPI Applications​

Identify imbalances and communications issues in MPI-enabled applications.​
 

GPU Profiling Tutorials

Profile an OpenMP Offload Application That Runs on a GPU​

Build and compile an OpenMP application offloaded onto an Intel GPU. Use Intel VTune Profiler to run analyses with GPU capabilities (HPC performance characterization, GPU offload, and GPU compute and media hot spots) on the OpenMP application, and then examine the results.​

Profile a SYCL* Application Running on a GPU​

Learn how to use Intel VTune Profiler to run a GPU analysis on the SYCL application and examine the results. ​
