or should care when used in parallel implementations java.util.arrays.parallelsort(t[] a, comparator<? super t> cmp) ? the comparison method nature pure function evaluated against objects may considered immutable @ least during sorting operation. mutating objects during sorting break essential assumption of sorting algorithm, order imposed comparator stable throughout operation. the above implies that, although comparator must thread-safe when used in parallel sort, given no special effort. on flip side, need make sure doesn't contain thread-unsafe code 1 reason or another, such using thread-unsafe collaborator instance shared across invocations of compare() .

cloud - Microsoft HPC pack / MPI , scheduler not regrowing task in job? -

-
i have job composed 3 tasks: task 1 : min 1, max 4 nodes task 2 : min 1, max 1 node task 3 : min 1, max 4 nodes my scheduler set queued, graceful preemption , adjust resources automatically. jobs scheduled via service on target machine, same priority. here question: 1 job queued, sometimes, scheduler allocates 1 node task 3, if there no other jobs queued. working intended? trial , error can see if task 1 + 2 doesn't take time, task3 have 4 nodes allocated. otherwise, if task1+2 takes little longer (20 mins or so) task3 gets allocated 1 node only. i'm not sure if working intended or if should write kind of service periodically checks queue status , if needs be, changes task3 minimum nodes requirement before task2 finishes course of action. any insight appreciated, thanks!
