Dear all, I have one question regarding the GC threads execution time distribution, and would like to know if Jikes has the similar flag or way to implement one. Thank you all in advance! The flag in Hotspot, "-XX:+PrintGCTaskTimeStamps", can print the usage as following, VM-Thread 17672326 17673726 17674290GC-Thread 0 entries: 4 [ old-to-young-roots-task 17672442 17672479 ] [ old-to-young-roots-task 17672479 17672496 ] [ thread-roots-task 17672496 17672691 ] [ steal-task 17672692 17673678 ]GC-Thread 1 entries: 9 [ old-to-young-roots-task 17672434 17672482 ] [ serial-old-to-young-roots-task 17672483 17672502 ] [ thread-roots-task 17672503 17672572 ] [ thread-roots-task 17672572 17672580 ] [ thread-roots-task 17672580 17672580 ] [ scavenge-roots-task 17672581 17672582 ] [ scavenge-roots-task 17672583 17672641 ] [ steal-task 17672641 17673677 ] [ waitfor-barrier-task 17673678 17673693 ]GC-Thread 2 entries: 10 [ noop task 17672421 17672422 ] [ thread-roots-task 17672523 17672574 ] [ thread-roots-task 17672574 17672575 ] [ thread-roots-task 17672575 17672576 ] [ thread-roots-task 17672576 17672581 ] [ scavenge-roots-task 17672581 17672582 ] [ scavenge-roots-task 17672582 17672584 ] [ scavenge-roots-task 17672584 17672585 ] [ scavenge-roots-task 17672585 17672585 ] [ steal-task 17672585 17673677 ]GC-Thread 3 entries: 10 [ old-to-young-roots-task 17672454 17672484 ] [ scavenge-roots-task 17672485 17672487 ] [ scavenge-roots-task 17672487 17672490 ] [ thread-roots-task 17672490 17672572 ] [ thread-roots-task 17672572 17672573 ] [ thread-roots-task 17672573 17672574 ] [ thread-roots-task 17672574 17672575 ] [ thread-roots-task 17672575 17672579 ] [ thread-roots-task 17672580 17672603 ] [ steal-task 17672603 17673677 ] Thanks!BestJunjie ------------------------------------------------------------------------------ _______________________________________________ Jikesrvm-researchers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/jikesrvm-researchers
