Detailed Description

This class contains thread configuration it supports parsing the ThreadConfig parameter and handling LockExecuteThreadToCPU etc...

This is used in ndb_mgmd when verifying configuration and by ndbmtd

TAP-TESTS are provided in mt_thr_config.cpp

Definition at line 36 of file mt_thr_config.hpp.

Member Function Documentation

int THRConfig::do_bindings ( )
protected

Check that no cpu_sets overlap

Check that no cpu_sets overlap

Remove all already bound threads from LockExecuteThreadToCPU-mask

don't count this one...

This is old mt.cpp : setcpuaffinity

let each LQH have it's own CPU and rest share...
