Bobo When using code like this def execute_run(list_out):
... do something
pool = ThreadPoolExecutor(6)
for i in list1:
for j in list2:
pool.submit(myfunc, list_out)
pool.join()
Assuming threads modify list_out, do they operate in a sync
Matteo I just started working on pthread API. I've been using different books and websites, and from their reports, pthread synchronization features (for example, those involving mutex locks) work for both uniprocessor and multiprocessor environments. But none

Angelo Regarding Linux 2.4 and Unix SRV4, I don't understand if a realtime process can preempt a timeshared process, otherwise the timeshared process will overtake the timeshared process. I think so because that's why realtime scheduling was introduced. Angelo
