DPS921/Intel Parallel Studio Inspector

Project Description

The scope of the project is to do determine how useful Intel Inspector is and how to use the debugging feature. The topics we are going to cover today is; what is Intel Parallel Studio Inspector, what are the pros and cons, and how to use Intel Parallel Studio Inspector. The goal of this is to educate ourselves and our classmate the importance of Intel Parallel Studio Inspector and how to use it.

What is Intel Parallel Studio Inspector

Intel Inspector is an easy-to-use memory and threading error debugger for C, C++, and Fortran applications that run on windows and Linux. It helps find and fix problems- such as memory leaks and deadlocks-before they hinder productivity and time-to-market. Inspector is a correctness checking program that helps you find and fix problem like memory leaks and deadlocks. There are two distinct side of the inspector coin design to target specific type of problem: threading error and memory error.

Reliability: find deadlocks and memory errors that cause lockups & crashes

Security: Find memory and threading vulnerabilities used by hackers

Accuracy: Identify memory corruption and race conditions to eliminate erroneous results

Different Deadlocks level

The threading and memory focus each level of analysis. Which progressive gets more details in cost of higher overhead. Each level are level 1: detects deadlock, level 2: detect deadlocks & data races, and level 3: locate deadlocks & data races.

Detect Deadlocks: when two or more threads are permanently stuck because no thread will give up its current lock until it can take the next one. But that lock is being held by another thread in the same position.

Detect deadlocks & data races: will do exactly what I explained earlier plus detect data races. Data races is when the outcome of an operation can change depending on what order the thread reached in.

Locate deadlocks & data races: is more detail with a smaller granularity deeper default stack frame depth and configurable scope.
