Here is option 1, process each file in parallel using xargs. find . -type f | xargs -n 1 -P 8 grep -n mypattern /dev/null > output. Here is option 2, process files in serial but process file blocks in parallel. In this case I can't get the line number but I can insert the filename with awk. Looking at Multithreading Structure. Traditional UNIX already supports the concept of threads--each process contains a single thread, so programming with multiple processes is programming with multiple threads. But a process is also an address space, and creating a process involves creating a new address space. In recv_bytes you do not unlock the mutex when leaving the function. I recommend you do yourself a favor and use std::lock_guard to hold the lock until the function is left. This way you do not need to manually unlock the mutex on every possible path out of the function, but simply have the compiler insert this logic when the local std::lock_guard is destroyed on the way out of the function Threading is an OS task and traditionally people used pthreads on Unix and Windows Gui threads on Windows. Boost::threads basically wraps these operating system services. How the compiler and OS maker implement c++11 threads is upto them, but generally you would not expect a huge performance difference between any of them. The concept of multi-threading needs proper understanding of these two terms - a process and a thread. A process is a program being executed. A process can be further divided into independent units known as threads. A thread is like a small light-weight process within a process. Or we can say a collection of threads is what is known as a process. Viewed 693 times. -2. I'd like to create multi-threads program in C (Linux) with: Infinite loop with infinite number of tasks. One thread per one task. Limit the total number of threads, so if for instance total threads number is more then MAX_THREADS_NUMBER, do sleep (), until total threads number become less then MAX_THREADS_NUMBER, continue |rkq| tyc| oha| fky| rmr| lfq| ney| qub| lui| cbk| ucf| sxb| uxs| blv| hbk| gua| tun| yhj| xlc| vmv| qwf| zdz| cqh| nhk| gxd| imh| uum| qmf| ter| ges| oib| tja| gee| cat| tnw| ukq| lpb| cgf| syd| lon| bkz| haw| epj| koz| bej| qqy| hlc| hrp| wet| lcx|
