* 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
The nondeterministic nature of threading errors makes it hard to reproduce. Intel Inspector detects and locates threading errors that include
race condition
A race condition or race hazard is the condition of an electronics, software, or other system where the system's substantive behavior is dependent on the sequence or timing of other uncontrollable events. It becomes a bug when one or more of t ...

In concurrent computing, deadlock is any situation in which no member of some group of entities can proceed because each waits for another member, including itself, to take action, such as sending a message or, more commonly, releasing a lo ...

In computing, an uninitialized variable is a variable that is declared but is not set to a definite known value before it is used. It will have ''some'' value, but not a predictable one. As such, it is a programming error and a common source of bu ...
s, use of invalid memory references, mismatched memory, allocation and deallocation, stack memory checks, and stack trace with controllable stack trace depth. Intel Inspector finds these errors and integrates with a debugger to identify the associated issues. It also diagnoses memory growth and locates the call stack causing it.
Intel Inspector has integration with debuggers (Microsoft VS debugger, GDB) so that Inspector automatically detects an error and places a debugger breakpoint at the problematic code location, allowing the user to investigate the details in a debugger.
The tool also detects persistent memory errors. 3D XPoint is a new emerging persistent memory technology for the data centers. Inspector detects persistent memory errors such as redundant cache flushes, memory fences, out-of-order persistent memory stores, incorrect undo logging etc.
Intel Inspector is available for free as a stand-alone tool, as part of Intel
oneAPI HPC and IoT Toolkits. Optional paid commercial support is available for the Intel HPC and IoT Toolkits.
