What I said is very clear, the OS can't access user-level thread, right ? so schedular can't schedule them ... I may be missing something, but this point is not wrong... if you can jot down some basic points for a user-level thread, then surely there is only thing at the top, and that's noting but the fact that "OS doesn't know about the user-level threads and thas why it can't schedule them seperately on multiple processors on SMP"... Please tell me where exactly I am wrong... Thanks. Sumit Sharma.
