2. 1. Towards Low-Complexity Scalable Shared-Memory Architectures

   Author : Håkan Zeffer; Erik Hagersten; John Carter; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; shared memory; distributed shared memory; hardware-software trade-off; software coherence; coherence profiling; remote access cache; chip multiprocessor; simultaneous multi threading; simulation; workload characterization; statistical cache model; Computer engineering; Datorteknik;

   Abstract : Plentiful research has addressed low-complexity software-based shared-memory systems since the idea was first introduced more than two decades ago. However, software-coherent systems have not been very successful in the commercial marketplace. We believe there are two main reasons for this: lack of performance and/or lack of binary compatibility. READ MORE

4. 2. Software Techniques for Distributed Shared Memory

   Author : Zoran Radovic; Erik Hagersten; Sandhya Dwarkadas; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; synchronization; distributed shared memory; write permission cache; nonuniform communication architecture; node affinity; locality; hardware-software trade-off; profiling; flexibility; trap-based memory architecture; Computer engineering; Datorteknik; Data- och systemvetenskap; Computer Systems Sciences;

   Abstract : In large multiprocessors, the access to shared memory is often nonuniform, and may vary as much as ten times for some distributed shared-memory architectures (DSMs). This dissertation identifies another important nonuniform property of DSM systems: nonuniform communication architecture, NUCA. READ MORE

5. 3. Iterative and Adaptive PDE Solvers for Shared Memory Architectures

   Author : Henrik Löf; Jarmo Rantakokko; Sverker Holmgren; Erik Hagersten; Mark Bull; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; partial differential equations; iterative methods; finite elements; conjugate gradients; adaptive mesh refinement; multigrid; cc-NUMA; distributed shared memory; OpenMP; page migration; TLB shoot-down; bandwidth minimization; reverse Cuthill-McKee; migrate-on-next-touch; affinity; temporal locality; chip multiprocessors; CMP; Beräkningsvetenskap; Scientific Computing;

   Abstract : Scientific computing is used frequently in an increasing number of disciplines to accelerate scientific discovery. Many such computing problems involve the numerical solution of partial differential equations (PDE). READ MORE

6. 4. Hardware–Software Tradeoffs in Shared-Memory Implementations

   Author : Håkan Zeffer; Erik Hagersten; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer Science;

   Abstract : Shared-memory architectures represent a class of parallel computer systems commonly used in the commercial and technical market. While shared-memory servers typically come in a large variety of configurations and sizes, the advance in semiconductor technology have set the trend towards multiple cores per die and multiple threads per core.

7. 5. Scientific Computing on Multicore Architectures

   Author : Martin Tillenius; Elisabeth Larsson; Sverker Holmgren; Jakub Kurzak; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; multicore; scientific computing; shared memory parallelism; task-based programming; parallel programming model; task scheduling; data versioning; Beräkningsvetenskap; Scientific Computing;

   Abstract : Computer simulations are an indispensable tool for scientists to gain new insights about nature. Simulations of natural phenomena are usually large, and limited by the available computer resources. READ MORE
