ANTS 4 OMP Interrupt Error

Question

I downloaded trial versions of the ANTS and dotTrace profiles.

When profiling in ANTS, at some point the program stops, and I get this error in the console window:

system error (-2147467259): __kmp_setaffinity: SetThreadAffinityMask: Unspecified error

OMP cancellation: fatal system error detected.

Program profiles without drama in dotTrace. What does the error mean and is it a problem with my code or with ANTS?

Answer 1

ANTS Profiler must establish a thread binding in order to maintain complex cross-thread synchronization, which will slow down the application and seriously complicate Profiler code.

Win32 API "SetThreadAffinityMask" - , , , % userprofile%\Local Settings\Application Data\Red Gate\ANTS Performance Profiler 5\PerformanceProfilerSettings.xml UseThreadAffinity False.
