I was thinking ...
while(pthread_create(&path, NULL, counter, file));
is that right? (1 Reply)

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)

PTHREAD_JOIN(3) BSD Library Functions Manual PTHREAD_JOIN(3)
NAME
pthread_join -- wait for thread termination
LIBRARY
POSIX Threads Library (libpthread, -lpthread)
SYNOPSIS
#include <pthread.h>
int
pthread_join(pthread_t thread, void **value_ptr);
DESCRIPTION
The pthread_join() function suspends execution of the calling thread until the target thread terminates unless the target thread has already
terminated.
On return from a successful pthread_join() call with a non-NULL value_ptr argument, the value passed to pthread_exit() by the terminating
thread is stored in the location referenced by value_ptr. When a pthread_join() returns successfully, the target thread has been terminated.
The results of multiple simultaneous calls to pthread_join() specifying the same target thread are undefined. If the thread calling
pthread_join() is cancelled, then the target thread is not detached.
A thread that has exited but remains unjoined counts against _POSIX_THREAD_THREADS_MAX.
RETURN VALUES
If successful, the pthread_join() function will return zero. Otherwise an error number will be returned to indicate the error.
ERRORS
pthread_join() shall fail if:
[EINVAL] The value specified by thread does not refer to a joinable thread.
[ESRCH] No thread could be found corresponding to that specified by the given thread ID, thread.
pthread_join() may fail if:
[EDEADLK] A deadlock was detected or the value of thread specifies the calling thread.
SEE ALSO
wait(2), pthread_create(3)
STANDARDS
The function conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
