BigRamTester run options -Xlog:gc*=debug,gc+phases+task=trace,gc+task+stats=trace,gc+refine=info:x.log -Xms20G -Xmx20G BigRamTester on a 2x10x2 machine.
Look at the attached log file for the task queue stats, particularly the new columns snotfull (indicating that we popped from the overflow queue while the shared queue has not been full) and sempty (indicating that we popped from the overflow queue while shared queue has been empty).
Relevant patches attached.
