* Save money - Find and root cause errors early before you release * Save time - Quickly debug intermittent races & deadlocks * Easy - No special builds! Use your normal build * Eliminate false errors and speed up analysis by using an API to mark memory that should not be analyzed * Intel Inspector can find both memory and threading errors on MPI applications. Performing an initial analysis on a single shared memory system will identify many errors, and additional analysis can also be run on a cluster. Results are sorted by rank. * Memory errors like leaks, corruption and illegal accesses can be very hard to find without a tool. Threading errors like races and deadlocks can be even harder because they are normally non-deterministic and difficult to reproduce. Intel® Inspector finds errors and makes them deterministic and debuggable.

* Xdebug's basic functions include the display of stack traces on error conditions, maximum nesting level protection and time tracking. * The debug information that Xdebug can provide includes the following: - stack and function traces in error messages with: - full parameter display for user defined functions - function name, file name and line indications - support for member functions - memory allocation - protection for infinite recursions * Xdebug also provides: - profiling information for PHP scripts - code coverage analysis - Capabilities to debug your scripts interactively with a debugger front-end.
