Hello everybody,
i want to use the multithread core to read/write the shared memory, and
all the thread
should know the info of the shared memory. normally, we use the
spin_lock,or read_lock,
write_lock, but when we test the performance of our programm,we found that
the lock result a
very bad performance.
so i need your help, if you have some experiences about this.
every thread should konw the info of shared memory, but if we use signal,
we still have
to use the lock to make sure that one thread to write the memory .
Thank you very much.
sorry of my poor english.
sno
