- // 50 user-level threads in ready state and only 2 or 3 LWPs assigned

- // I suspect the problem is related to libthread's LWP
- // pool management and to the kernel's SIGBLOCKING "last LWP parked"
- // upcall policy.
- //
- // The following code is palliative -- it attempts to ensure that our
- // process has sufficient LWPs to take advantage of multiple PEs.
- // Proper long-term cures include using user-level threads bound to LWPs
- // (THR_BOUND) or using LWP-based synchronization. Note that there is a
- // slight timing window with respect to sampling _os_thread_count, but
- // the race is benign. Also, we should periodically recompute
- // _processors_online as the min of SC_NPROCESSORS_ONLN and the
- // the number of PEs in our partition. You might be tempted to use
- // THR_NEW_LWP here, but I'd recommend against it as that could
- // result in undesirable growth of the libthread's LWP pool.
- // The fix below isn't sufficient; for instance, it doesn't take into count
- // LWPs parked on IO. It does, however, help certain CPU-bound benchmarks.
- //
- // Some pathologies this scheme doesn't handle:
- // * Threads can block, releasing the LWPs. The LWPs can age out.
- // When a large number of threads become ready again there aren't
- // enough LWPs available to service them. This can occur when the
- // number of ready threads oscillates.
- // * LWPs/Threads park on IO, thus taking the LWP out of circulation.
- //
