From: Terry Lambert <terry@lambert.org> Date: Mon, 20 May 1996 22:21:33 -0700 (MST) The SunOS LWP's are pretty easy. Actually SunOS does do lwp scheduling where it checks for AST's etc. although I don't know how relevant that is to whats being discussed. Furthermore, the way Solaris does threads in the kernel has been proven to be a lose (pre-emption, a billion mutexes in the kernel, another thousand read writer locks) and expect the industry to move in "another" direction. Computer science has proven that current smp technology (read as: what SVR4.2MP based kernels do right now) cannot scale past 32 cpu's without an exponential loss in performance. Clustering is the answer and can scale to more CPU's than you can count in an unsigned char. ;-) Later, David S. Miller davem@caip.rutgers.edu
