Topics
- Sections 1.1 and 1.1.2
- Update performance trends in multiprocessors.
- Section 1.1.1, first half: Scientific/engineering application trends
- What characterizes present-day applications?
- How much memory, processor time, etc.?
- How high is the speedup?
- Section 1.1.1, second half: Commercial application trends
- What characterizes present-day applications?
- How much memory, processor time, etc.?
- How high is the speedup?
- Section 1.1.3: Architectural trends
- How have architectures changed in the past 10 years?
- Update Figs. 1.8 and 1.9 with new points, for 2000, 2002, 2004, 2006, and 2007.
Architectural Trends- This summary give a detail observation of architectural trends. It also highlights the concepts of VLIW(Very Long Instruction Word), Multi-threading, Multi-core CPUs, and Speculative Execution. It also updates Figs. 1.8 and 1.9 with new points, for 2000, 2002, 2004, 2006, and 2007.
- Section 1.1.4: Supercomputers
- Compare current supercomputers with those of 10 yrs. ago.
- Update Figures 1.10 to 1.12 with new data points. For 1.12, consult top500.org.
Supercomputers- This summary give a detail description of the definition of what a supercomputer is, the evolution of the supercomputer's architecture and performance, and explores the main metric (LINPACK Benchmark Suite) for evaluating the effectiveness of supercomputers. It also takes a look at the most dominant supercomputers of the last 10 years.
- Sections 1.2.1 and 1.2.4: Communication architecture
- Trends in last 10 years.
- How has data parallelism found its way into shared-memory and message-passing machines? An early example would be MMX.
- Would you change the number of layers in Fig. 1.13?
- Section 1.2.2: Shared address space
- Any changes in the organization of address spaces in the last 10 years?
- Are the interconnection structures different in new computers now than they were 10 years ago?
- What is the size and capacity of current SMPs?
- How have supercomputers evolved since the Cray T3E?
- Section 1.2.3: Message passing
- Are blade servers an extension of message passing?
- How have blade architectures evolved over the past 10 years?
Message Passing This summary highlights the typical structure, advantages and gives a detailed introduction of what message passing is.
- Section 1.2.5: Trends in vector processing and array processing.
- New machines have recently been announced. Why will this be an important architectural dimension in the coming years?
- Section 1.2.6
- New developments in dataflow and systolic architectures, if any.
- Or if not, why are these styles not evolving with time?
- Sections 1.3.1 and 1.3.2: Communication and programming model
- How have reordering strategies evolved to accommodate larger multicomputers?
- Have new kinds of synchronization operations been developed?
- I doubt that other topics covered in these sections have changed much, but do check.
- Sections 1.3.3 and 1.3.4: Most changes here are probably related to performance metrics.
- Cite other models for measuring artifacts such as data-transfer time, overhead, occupancy, and communication cost. Focus on the models that are most useful in practice.
