multiples of these nodes are interconnected on a higher level Examples of systems with such a hierarchical memory architecture are the Sequent NUMA-Q, the SGI Origin 2000/3000 series, and the IBM Blue Gene/L (van der Steen and Dongarra [193]), which is the world s fastest computer at the time this is written [186] Motivations The following paragraphs brie y look at the motivations for the different architectures Centralized shared-memory architectures are an intuitive extension of a single processor architecture; however, the contention for the communication resources to the central memory signi cantly limits the scalability of these machines Bus-based systems therefore have a small number of processors (usually 8), for example, systems with 86 processors, and only more sophisticated interconnection networks allow these systems to scale up to 64 processors For example, in the Sun Enterprise series (van der Steen and Dongarra [193]), systems with low model numbers (eg, 3000) are connected by a bus, whereas the high-end model, the Sun Enterprise 10000, uses a crossbar (see Section 22) for up to 64 processors In contrast, distributed memory architectures with message passing allow a much simpler system design, but their programming becomes more complicated In fact, commodity PCs can be connected via a commodity network (eg, Ethernet) to build a so-called cluster of workstations or PCs (Patterson [147], Sterling et al [181]) The big advantage of distributed memory systems is their much better scalability Hence, it is no surprise that the massively parallel processors (MPPs) are distributed memory systems using message passing with up to hundred thousand processors (eg, Thinking Machines CM-5, Intel Paragon, and IBM Blue Gene/L) Distributed shared-memory architectures try to integrate both approaches They provide the ease of the shared-memory programming paradigm and bene t from the scalability of distributed memory systems, for instance, Cray T3D/T3E, the SGI Origin 2000/3000 series, or the HP SuperDome series (van der Steen and Dongarra [193]) Yet, shared-memory programming of these architectures can have limited ef ciency in as much as the heterogeneous access times to memory are often hidden from the programmer 213 Programming Paradigms and Models Shared-Memory Versus Message Passing Programming The programming paradigms for parallel systems have a strong correspondence to the memory access policies of multiprocessors Fundamentally, one can distinguish between shared-memory and message passing programming In the former paradigm, every processor has full access to the shared memory, and communication between the parallel processors is done implicitly via the memory Only concurrent access to the same memory location needs explicit synchronization of the processors In message passing programming, every exchange of data among processors must be explicitly expressed with send and receive commands It must be noted that the employed programming paradigm does not always correspond to the underlying memory organization of the target system Message passing.

^ ^ corresponds to the value of l2 and the error bars to the standard deviation of l2 or the 68.26% con dence intervals. We see that for our datasets the Weibull model does substantially better than the others (except for FTP.DATA, consistent with Paxson and Floyd [35]) although the value of the discrepancy is quite substantial for some of the application types and some datasets. In fact, for all CMU datasets the Weibull model is statistically better than the other models in 203 of 240 cases, it is indistinguishable in 25 cases, and is beaten by one of the other models in only 12 instances. Actually the Pareto model is better in eight cases, while the exponential model is better in three cases, and the lognormal model in one case. For the AT&T datasets the Weibull model is statistically better than the other models in 90 of 95 instances, it is indistinguishable from the Pareto or the exponential model in three instances, and it is beaten by the Pareto model in only two instances. For the LBL and DEC datasets we observe that the Weibull distribution is capable of modeling some but not all applications. For example, the Weibull distribution performs very well for SMTP, NNTP, and FTP.CONN connections but poorly for HTTP and TELNET connections for the 1993 LBL-7 dataset. An explanation for HTTP is that very few people were using it at the time of the collection of the trace. Therefore the sample may not be appropriate. For TELNET it seems that a nonstationary approach is
