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

6. 4. Efficient Memory Modeling During Simulation and Native Execution

   Author : Nikos Nikoleris; Erik Hagersten; Lieven Eeckhout; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; performance analysis; cache performance; multicore performance; memory system; memory bandwidth; memory contention; performance prediction; multi-threading; multiprocessing systems; program diagnostics; commodity multicores; multithreaded program resource requirements; performance counters; scalability bottleneck; scalability improvement; Computer Science; Datavetenskap;

   Abstract : Application performance on computer processors depends on a number of complex architectural and microarchitectural design decisions. Consequently, computer architects rely on performance modeling to improve future processors without building prototypes. READ MORE

7. 5. Efficient and Practical Non-Blocking Data Structures

   Author : Håkan Sundell; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; shared data structure; abstract data type; snapshot; lock-free; priority queue; synchronization; non-blocking; skip list; shared memory; deque; real-time; doubly linked list; dictionary; wait-free; shared register;

   Abstract : This thesis deals with how to design and implement efficient, practical and reliable concurrent data structures. The design method using mutual exclusion incurs serious drawbacks, whereas the alternative non-blocking techniques avoid those problems and also admit improved parallelism. READ MORE
