Vtune Profiler Features

The Vtune Profiler has a variety of features that provide information to assist in the optimization of application performance, system performance. The profiler also assists in system configuration for HPC, Cloud, IoT, media, storage, etc.

The profiler provides compatibility for a variety of systems and platforms that include the following:

    CPU, GPU, and FGPA

    Any combination of the following languages: SYCL, C, C++, C+, Fortran, OpenCL, Python, Google Go, Java, .NET, Assembly

    Optimized performance that avoids power or thermal throttling 

    Collection of coarse-grained data over extended periods with details results including mapping to source code
