TLS Synchronization

Question Text​

Is placing var from support/race-condition/c/race_condition_tls.c in the TLS a valid form of synchronization?

Question Answers​

  • No, because the race condition remains. It just doesn't manifest itself anymore
  • No, because the threads now access different variables, not the same one

  • Yes, because we now remove the race condition

  • Yes, because now the result is correct

Feedback​

Synchronization means that both threads should access the same variable, whereas placing it in the TLS makes each of them access a copy of the variable.
