...uot;wait queues" where threads may be placed to enforce caps. I would like to make this visible through DTrace and to add two new probes to the sched provider with the following semantics: cpucaps-sleep Probe that fires immediately before the current thread is placed on a wait queue. The lwpsinfo_t of the waiting thread is pointed to by args[0]. The psinfo_t of the process containing the waiting thread is pointed to by args[1]. cpucaps-wakeup Probe that fires immediately after a thread is removed from a wait queue. The lwpsinfo_t of the waiting thread is pointed to by args[0]. The ps...

Hi: S10 has physical domain control data structure and physical domain control data structure are defined for platform dependent sun4u architecture. From T2000, logical domain will be introduced with new firmware on virtualization. DCS May I ask a few questions below: (1) it seems common psinfo_t and cpuinfo_t does address platform specific information. What is the proper way to access the domain realted structure so that I can lookup related cpuset and domain state or domain heartbeat ? (2) how D structure or uts structure provide the visiability to understand if the proces...

Does dtrace have a problem catching the return from memset on Mac OSX? The script below catches the entry just fine but the return clause is never entered. Thanks, Joel --- pid$target::memset:entry /arg1 == 0/ { self->size = arg2; self->ts = timestamp; self->vts = vtimestamp; } pid$target::memset:return /self->size/ { @ts = sum(timestamp - self->ts); @vts =

Hi, Chris (cc) and I try to get the SGE master monitor work with Apple Leopard dtrace. Unfortunately we are stuck with the error msg below. Anyone having an idea what could be the cause? What I can rule out as cause is function inlining for the reasons explained below. Background information on SGE master monitor implementation is under http://wiki.gridengine.info/wiki/index.php/Dtrace
