The implementation assumes that processor IDs are in numerical order from 0 to N - 1, where N - count of processor in the system

Member Function Documentation

current_processor()

static unsigned int cds::OS::Linux::topology::current_processor ( )

inlinestatic

Get current processor number.

Caveat: current_processor calls system sched_getcpu function that may not be defined for target system (sched_getcpu is available since glibc 2.6). If sched_getcpu is not defined the function emulates "current processor number" using thread-specific data. You may manually disable the sched_getcpu usage compiling with -DCDS_LINUX_NO_sched_getcpu.
