PTHREAD_TESTCANCEL(3)					     Linux Programmer's Manual					     PTHREAD_TESTCANCEL(3)

NAME
pthread_testcancel - request delivery of any pending cancellation request SYNOPSIS
#include <pthread.h> void pthread_testcancel(void); Compile and link with -pthread. DESCRIPTION
Calling pthread_testcancel() creates a cancellation point within the calling thread, so that a thread that is otherwise executing code that contains no cancellation points will respond to a cancellation request. If cancelability is disabled (using pthread_setcancelstate(3)), or no cancellation request is pending, then a call to pthread_cancel() has no effect. RETURN VALUE
This function does not return a value. If the calling thread is canceled as a consequence of a call to this function, then the function does not return. ERRORS
This function always succeeds. CONFORMING TO
POSIX.1-2001. EXAMPLE
See pthread_cleanup_push(3). SEE ALSO
pthread_cancel(3), pthread_cleanup_push(3), pthread_setcancelstate(3), pthreads(7) COLOPHON

a pthread problem

Hello, I run my pthread code on Linux with 4 processors. However, the speed up is only 2 times. The code is about solving equation (G+s(i)C)z(i)=B*us(i), i=1,...,n. Here G,C are m*m matrix, B*us(i) is a m*1 vector and s(i) are n different numbers. I need to solve the equation n times to... (2 Replies)
