1. 11. Efficient synchronization and coherence for nonuniform communication architectures

   Författare :Zoran Radović; Erik Hagersten; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer Science;

   Sammanfattning : Nonuniformity is a common characteristic of contemporary computer systems, mainly because of physical distances in computer designs. In large multiprocessors, the access to shared memory is often nonuniform, and may vary as much as ten times for some nonuniform memory access (NUMA) architectures, depending on if the memory is close to the requesting processor or not.

3. 12. Algorithms for synchronization and consistency in concurrent system services

   Författare :Anders Gidenstam; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; threading; plausible clocks; memory management; event ordering; lock-free; optimistic causal order; nonblocking; group communication; synchronization; memory reclamation; time stamping system; logical clocks; atomic registers.;

   Sammanfattning : Synchronization, consistency and scalability are important issues in the design of concurrent computer system services. In this thesis we study the application of optimistic and scalable methods in concurrent system services. LÄS MER

4. 13. Lock-Based Resource Sharing in Real-Time Multiprocessor Platforms

   Författare :Sara Afshar; Thomas Nolte; Moris Behnam; Marko Bertogna; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

   Sammanfattning : Embedded systems are typically resource constrained, i.e., resources such as processors, I/O devices, shared buffers or shared memory can be limited for tasks in the system. Therefore, techniques that enable an efficient usage of such resources are of great importance. LÄS MER
