[PATCH 3/3] powerpc: enabled asymmetric SMT scheduling on POWER7
The POWER7 core has dynamic SMT mode switching which is controlled by the hypervisor. There are 3 SMT modes: SMT1 uses thread 0 SMT2 uses threads 0 & 1 SMT4 uses threads 0, 1, 2 & 3 When in any particular SMT mode, all threads have the same performance as each other (ie. at any moment in time, all threads pe... 8 Jun 2010 01:29

[PATCH 0/3] sched: asymmetrical packing for POWER7 SMT4
This patch series implements asymmetric SMT packing which ensures consistently good performance on POWER7. Without this series, tasks will vary in performance by around +/-30% on POWER7 This new version is based on help from Vatsa and Vaidy in an attempt to answer concerns that Peter Zijlstra had about the origi... 8 Jun 2010 01:29
