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_testcancel()
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).

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)
