....on a multiprocessor. By addressing the needs of the workstation environment, our proposal makes multiple contexts more attractive for commodity microprocessors. 1 Introduction Large scale multiprocessors, such as the one shown in Figure 1, are increasingly built using commodity microprocessors [2, 16]. While these commodity microprocessors provide a relatively lowcost compute node, their performance depends heavily on employing a sophisticated cache hierarchy to insulate the processor from the long remote memory latency. Providing the ability to cache shared data [16] can greatly increase the ....

On Bounding Time and Space for Multiprocessor Garbage.. - Guy Blelloch Perry (1999)   (1 citation)  (Correct)

....parallelized. The TestAndSet and FetchAndAdd primitives can be implemented in parallel using a combining network, and it has been argued that they can be made no slower than a memory reference to the shared memory [14, 28] Furthermore several machines have supported these primitives in hardware [13, 27, 20, 31, 18]. Most current symmetric multiprocessors support the TestAndSet operation directly, but not the FetchAndAdd. On the Sun Enterprise Server, for example, TestAndSet only requires about the same time as a memory reference (15 cycles if in second level cache and 60 cycles if in shared memory) 23] ....

....like the Silicon Graphics Power Series [6] Whilst this machine cannot deliver the sustained performed mentioned earlier in the paper, the study allowed us to evaluate the effectiveness of parallelising the model. There are now much larger and faster shared memory machines (like the CRAY T3D [7], the Convex SPP [8] and the Kendall Square Research KSR2 [9] which are capable of delivering the required performance. These machine utilise a distributed virtual shared memory unlike the current shared memory machines. Figure 2 Sample ozone contours The generation of ozone contours requires ....
