https://community.hpe.com/t5/operating-system-linux/how-to-change-a-thread-s-scheduling-priority/m-p/4055109#M64815 In HPUX, you can use the pthread_setschedparam() to change a thread’s scheduling priority. But when this code is used in RHELv4, I get EPERM error.<BR /><BR />I modified /etc/security/limits.conf to get ability to change process priority, but it had no effects. How does one change a thread’s scheduling priority in Linux?<BR /><BR />Thanks<BR /><BR />Tim<BR /> Thu, 16 Aug 2007 00:56:52 GMT Tim Yeung_1 2007-08-16T00:56:52Z https://community.hpe.com/t5/operating-system-linux/how-to-change-a-thread-s-scheduling-priority/m-p/4055109#M64815 In HPUX, you can use the pthread_setschedparam() to change a thread’s scheduling priority.
