Intel® Parallel Studio XE

Intel Parallel Studio XE is a software development tool suite for compiling applications and optimizing performance with less effort.

The Intel C++ Compiler is not the only tool that comes with IPS XE 2019. It also includes next applications:

• Intel® Advisor
• Intel® Inspector
• Intel® VTune™ Amplifier

Let's take a quick look at each of them:

Intel® Advisor

Vectorization optimization and thread prototyping.

Use this tool in the vectorization and threading stages of the flow.

Intel® Inspector

Memory and thread debugger.

Use this tool to find races, deadlocks, and illegal memory accesses.

• Locate root cause errors early―before you release
• Quickly debug intermittent races and deadlocks

Intel® VTune™ Amplifier

Performance profiler.

Use this tool in the threading and bandwidth optimization stages and for advanced vectorization optimization.

• Save money: Locate root cause errors early―before you release
• Save time: Quickly debug intermittent races and deadlocks

Intel Inspector

Intel Inspector is a dynamic memory and threading error checking instrument to inspect serial and multi-threaded programs.

Intel Inspector comes with Intel Parallel Studio XE along with two other debugging tools - VTune and Advisor.

Create a project There are 2 ways to work with inspector.

• Run inspector directly from Visual Studio

This is the easiest and fastest way that requires no additional configurations.

• Run as a separate program.

Working with Intel Inspector application requires passing it a compiled version of your program. Additionally you may need to link some libraries (lib, dll, etc).

Configure a project Intel suggests using small data set sizes and load threads with small chunks of work..

This will reduce run time and the speed of the analysis.
