IBM SWG and STG Are Teaming on Software Optimization (Project Mason)

� Targeted whole-stack performance analysis and remediation of key software

– Deep analysis & tuning across full sw stacks– Focus on the POWER7 / POWER7+ / POWER8– Distinguish the Power architecture as a preferred platform for

software deployment– Focus on scalability

� Extensive collaboration across SWG and STG, leveraging and propagating skills

� Focused on realistic workloads run in customer-typical configurations, to ensure that recognized value is delivered

� Deliver out-of-the-box performance where possible, minimizing reliance on customer tuning

� Drive changes to field releases as soon as practical

Application

IBM Software

IBM Software automatically exploits

processor chip, threads, cache affinity, processor

binding, and memory affinity

available on POWER7 to optimize performance and deliver best value

– No redesign of application required

– No rewriting of business queries

– Near-Linear scalability

– Real-time analysis on concurrent threads

– Continuous availability with Power and AIX

– Only vendor to use decimal floating processor

Shared Processor Logical Partitions (LPAR’s)

� Multiple LPAR’s can share the same physical processors

� POWER hypervisor dynamically allocates CPU resource based on LPAR load

� Two types of LPAR configs:– Capped : LPAR cannot exceed its

entitled CPU capacity

– Uncapped : LPAR is free to exceeds its entitled CPU capacity if needed

� LPAR’s can be grouped into virtual poolsShared processor pool

DB2 Exploitation of Power Systems

� Performance of POWER7 and DB2– More cores and threads – 32 chips, 8 cores/chip, 4 threads/core

- Multi-year TPC-C, TPC-H and SAP benchmark leadership-Exploited by DB2 better than any other DBMS yielding up to 30-35% performance for certain workloads-DB2 threaded engine built to scale on large multi core servers

– Cache exploitation- Judicious use of L2 cache prefetch instruction embedded into DB2 to limit cache stalls- Careful placement of hot and critical structures along processor cache line boundaries

� Consolidation of DB2 on POWER7– PowerVM virtualization second to none

- Active Memory Sharing exploited by DB2 self tuning memory managerWhen peak demand hits, DB2 can immediately leverage additional resources

- Workload management integrated between AIX and DB2DB2 able to meet customers SLAs more easily

� Reliability of Power Systems and DB2– Power 3x – 4x more reliable than Linux on x86 – 99.997% availability with Power and AIX

DB2 tightly integrated with PowerHA and other HA features of AIX

DB2 engine source code is

compiled on AIX with its optimized compiler
