– AIX 6.1 TL8 and 7.1 TL2 introduce – Power 7 provides a register to control
support for 16 MB page sizes memory pre-fetching (DSCR – Data
Stream Control Register)
– Automatically enabled when AIX DSO
enhanced feature is installed – Controls pre-fetch enablement, depth
and stride of pre-fetching.
– DSO monitors TLB missed with large
memory workloads and automatically – DSCR control automatically enabled
does page size promotion when AIX DSO enhanced feature is
installed
– Targets System V shared memory
– DSO analyzes memory access patterns
and determines optimal values for DSCR
that can be applied at the LPAR or per-
process level
– DSCR management is dynamic and can
be continually adjusted based on
changing workload dynamics
