#define RECLAIM_DISTANCE 10
/*
- * Before going off node we want the VM to try and reclaim from the local
- * node. It does this if the remote distance is larger than RECLAIM_DISTANCE.
- * With the default REMOTE_DISTANCE of 20 and the default RECLAIM_DISTANCE of
- * 20, we never reclaim and go off node straight away.
- *
- * To fix this we choose a smaller value of RECLAIM_DISTANCE.
+ * Avoid creating an extra level of balancing (SD_ALLNODES) on the largest
+ * POWER7 boxes which have a maximum of 32 nodes.
