SAGE includes the C/C++ libraries listed below. For each library, determine whether or not (or to what extent) it is thread safe. == SAGE-related Problems ==

Line 6: Line 8:
"Be careful if your application uses libraries or other objects that don't explicitly guarantee thread-safeness. When in doubt, assume that they are not thread-safe until proven otherwise.
Thread-safeness: in a nutshell, refers an application's ability to execute multiple threads simultaneously without "clobbering" shared data or creating "race" conditions. For example, suppose that you use a library routine that accesses/modifies a global structure or location in memory. If two threads both call this routine it is possible that they may try to modify this global structure/memory location at the same time. If the routine does not employ some sort of synchronization constructs to prevent data corruption, then it is not thread-safe. The implication to users of external library routines is that if you aren't 100% certain the routine is thread-safe, then you take your chances with problems that could arise." -- from [http://www.llnl.gov/computing/tutorials/pthreads/ the pthreads tutorial]
