Constructor & Destructor Documentation

SemaphoreMapEntry()

tarch::mpi::BooleanSemaphore::BooleanSemaphoreService::SemaphoreMapEntry::SemaphoreMapEntry

(

)

Create new semaphore entry.

The default is that a semaphore is not locked. New entries should only be inserted by addMapEntryLazily() which in turn is triggered by tryLockSemaphoreOnGlobalMaster().

Field Documentation

locked

bool tarch::mpi::BooleanSemaphore::BooleanSemaphoreService::SemaphoreMapEntry::locked

Flag indicating if a semaphore is currently locked.

Definition at line 96 of file BooleanSemaphore.h.

rankThatLastLocked

int tarch::mpi::BooleanSemaphore::BooleanSemaphoreService::SemaphoreMapEntry::rankThatLastLocked

Bookkeeping of who has locked a semaphore last.

I originally wanted to use this one for some fairness checks, but this all became too complicated and did not pay off. Therefore, this flag is solely there for keeping track of historic data.
