This workshop was led by Roch Archambault, from the IBM Toronto Lab, and focused on their compiler technologies, specifically for the POWER architecture. The agenda for the 2-day workshop was:
Tuesday 17 February 2009
9:00-9:15 Introduction and overview of agenda
9:15-11:15 Compiler Overview - machine independent (Roch) Compiler overview (block diagrams, high level optimizations) and roadmap Compiler Details and flag enhancements O4, O5, qhot, qipa, inlining, stackcheck, pdf why qhot default in v10/11? useful information in listings
11:15-11:30 break
11:30-12:30 POWER6 overview - hardware (Jim) P6 processor (Caches, functional units, MC, fabric) SMT, prefetch, … Systems (HE, IH, L4, HV4, HV8) – focus on IH Including which exploit 2 MC, 2B vs. 4B vs. 8B fabric Clock speeds Hand Tuning Recommendations Separation of FP Compare and Branch FP Store double pair
