Tornado and Grand Central Dispatch: a quick lookTornado and Grand Central Dispatch: a quick lookPosted Sep 16, 2009 21:54 UTC (Wed) by ballombe (subscriber, #9523)Parent article: Tornado and Grand Central Dispatch: a quick look
What is killing wide-spread use of OpenMP is the lack of support for error recovery (restoring the program to a known state).
If an error occurs inside a library you link to in an OpenMP thread, you generally have no way of recovering.
Is GCD better in that regard ?
(By contrast the POSIX thread API let you do a pthread_exit() with a marker value that will notify the caller of the error and also provide a way to cancel the remaining threads)
