This is a part of my whole problem
As u can see in the vmstat output, 39 waiting processes are there and also the cpu is idle, when I check using Top command, i see that there is approximately 2 gb of RAM free which is not being used. Also cpu is approximately 80% idle.
Some(~10, which is very less, we generally run 30 of these parallely) really cpu intensive tasks have been made to run on this machine and their speed is very slow. neither are they executing fast(using the available cpu), nor are the waiting processes running. what is the meaning of this?
also from iostat output, i don't see lot of io happening.

Hi All,
Is there a max number of slabs that can be used per kernel module? I'm having a tough time finding out that kind of information, but the array 'node_zonelists' (mmzone.h) has a size of 5. I just want to avoid buffer overruns and other bad stuff.
Cheers,

Using pthreads is there a way to determine how many threads are waiting on a locked resource? I mean, once a shared resource is protected using e.g. pthread_rwlock_t or pthread_mutex_t one thread grabs the lock and other threads will go to sleep waiting for the resource to be available again. Is... (0 Replies)
