Wind River Support Network

Description

In Wind River Linux 1.4 pthreads are not scheduled on multiple cores on Cavium Octeon cn38xx. Running a simple test routine to schedule numerous threads in one process across all cores of the Cavium is not successful. It does appear that the scheduler is supporting the per process, thread affinity (( i.e. a core from the set of cores configured via sched_setaffinity() is used by the process), but all threads end up getting scheduled on this same core. IDENTIFIER = WIND00123031
