Processor Value Unit Licensing for MiddlewareEvolving the Structure to Provide a Foundation for the Future Processor Value Unit - Technology Education
Technology Education Agenda • What is a Processor • What is an nWay • Processor Performance • Historical • Strategies • Disparity • Processor Vendors are moving to Multi-core • Summary
Processor Definition is Important in Middleware Licensing • Single-core chips have 1 core per chip • Dual-core chips have 2 cores per chip • Quad-core chips have 4 cores per chip Multi-core chips Dual-core Chip Single-core Chip 1 2 1 IBM defines processor = core As do most Middleware Vendors…eg. Oracle and BEA However, some Hardware Vendors . . . Intel, AMD, and Sun define processor = chip
The Definition of nWay Differs by Hardware Vendor • 4 Processor Cores • 4 Single-core Chips • 8 Processor Cores • 4 Dual-core Chips Server Server 4 3 1 2 1 2 8 6 7 3 4 5 4Way 4Way or 8Way? • IBM System p & i, and HP 9000 call this an 8Way • Sun and all Intel/AMD vendors including IBM System x (xSeries) call this a 4Way All Hardware Vendors call this a 4Way
Most Middleware Vendors Count Processor Cores • 4 Processor Cores • 4 Single-core Chips • 8 Processor Cores • 4 Dual-core Chips Server Server 4 3 1 2 1 2 8 6 7 3 4 5 4Way 4Way or 8Way? Most Middleware Vendors say this Server has 8 Processors All Middleware Vendors say this Server has 4 Processors
Year 1 4 Proc Year 3 1 Core 2 Proc Year 5 1 Core 1 Proc 1 Core 1 Core 1 Core 1 Core 1 Core Constant Workload 1 Core 1 Core 1 Core 1 Core 1 Core 1 Core 1 Core 1 Core 1 Core Same Workload Processor Cores Are Not All Created Equal Today • Historically, a constant workload required fewer processor cores over time • Some processor cores increased performance faster than others • Today, the number of processor cores required for a given workload varies by processor technology
One Processor Core Improve Core Strategy Core Disparity Core Performance Multi-core Strategy Time Processor Core Performance Disparity Expected to Grow • The performance gap is growing between processor core technologies as a result of diverging strategies • Core performance improvement • Flat core performance, but increase cores per chip Increasing processor core performance disparity means traditional per processor licensing is not sustainable
Processor Vendors Are Moving to Multi-core • IBM Power introduced dual-core chips in 2001 • Octi-core chips introduced by Sun in 2005 • Most x86 servers sold in 2006 will have dual-core chips A sustainable licensing structure that addresses the processor performance disparity on these multi-core chips is required
Summary • Processor definition is important in middleware licensing • IBM SWG defines a processor = core • Number of nWays and processors NOT always the same • Processor Core performance disparity is expected to grow • Not all processor cores are created equal today • Two Strategies to Improve Chip Performance • All vendors moving to Multi-core chips • A sustainable licensing structure to address this processor performance disparity is required • Therefore IBM is announcing the Processor Value Unit licensing structure effective July 25, 2006
