Hi Chris, AIX is smart enough not to change the dispatching behaviour when this parameter is (inadvertently) used on POWER6 or even POWER5: You can use the command 'echo "vpm" | kdb | egrep "^Scal|^Eff"' to query the kernel about which mode is set and which mode is effective. In contrast to POWER7 you will see that the "Effective SMT Mode" on POWER5 and POWER6 will not change whatever vpm_throughput_mode is set.
