Thread of execution is the smallest sequence of programmed instructions that can be managed independently by scheduler. Thread is a component of process and so multiple threads can be associated in a process. Linux doesn’t have a separate threads per process limit, but has a limit on the total number of processes on the system (as threads just processes with a shared address space on Linux).
Our task is to find out maximum number of thread that can be created within a single process (maximum number of thread that pthread_create can create). Maximum number of threads can be seen is ubuntu by using command:
This thread limit for linux can be modified at runtime by writing desired limit to /proc/sys/kernel/threads-max.
Compile the following program on ubuntu operating system, to check maximum number of threads that can be created within a process in C.
cc filename.c -pthread where filename.c is the name with which file is saved.
Maximum number of thread within a Process is : 32754
