Introduction to Intel Advisor Vectorization
Thread Prototyping
Swiftly model, tune, and test the performance of multiple threading designs without disrupting development.
- Identify issues and fix them before implementing parallelism.
- Add threading to C, C++, C#, and Fortran code.
- Prototype the performance impact of different threaded designs and project scaling on systems with larger core counts to identify potential scaling without disrupting development or implementation.
- Find and eliminate data-sharing issues during design (when they're less expensive to fix).
Flow Graph Analyzer
Use a rapid visual prototyping environment for applications that can be expressed as flow graphs using Intel® oneAPI Threading Building Blocks (oneTBB) applications.
- Construct, validate, and model application design and performance before generating oneTBB code.
- Get insight into nested or top-level data-parallel algorithm efficiency.
In addition to oneTBB, Flow Graph Analyzer helps you to:
- Visualize and interact with SYCL asynchronous task graphs.
- Get insights into SYCL task scheduling inefficiencies.
- Speed up algorithm design and express data-parallel constructs more efficiently.
- Visualize and analyze OpenMP task dependence graphs for performance bottlenecks.

What Customers Are Saying
"We recommend using Intel MPI for best performance, and tools such as VTune Profiler and Advisor to help better understand performance optimizations and how to best migrate your workloads to the cloud. Intel Advisor and the roofline model really allows our customers to understand what is possible and what the performance could be for their specific workloads."
— Ilias Katsardis, HPC solution lead, Google Cloud Platform* service
"Intel Advisor made it easier to find the cause of bottlenecks and decide on next optimization steps. It provided data to help us forecast the performance gain before we invested significant effort in implementation."
— Igor Chernykh, assistant professor, Novosibirsk State University
"Intel Advisor has been extremely helpful in identifying the best pieces of code for parallelization. We can save several days of manual work by targeting the right loops. At the same time, we can use Intel Advisor to find potential thread safety issues to help avoid problems later on."
— Carlos Boneti, HPC software engineer, Schlumberger
