Simple but effective techniques for NUMA memory management

Memory and Thread Management on NUMA Systems

Memory allocation constructs to complement NUMA memory management

Nonuniform memory access time (referred to as NUMA) is an important feature in the design of large scale shared memory multiprocessors. However, one implication of the NUMA architecture is that locality of the data is crucial to performance. In the absence of any system support, the programmer is forced to explicitly manage these locality issues, signiicantly increasing the development time for...

MAP-numa: Access Patterns Used to Characterize the NUMA Memory Access Optimization Techniques and Algorithms

Some typical memory access patterns are provided and programmed in C, which can be used as benchmark to characterize the various techniques and algorithms aim to improve the performance of NUMA memory access. These access patterns, called MAP-numa (Memory Access Patterns for NUMA), currently include three classes, whose working data sets are corresponding to 1-dimension array, 2-dimension matri...

Evaluation of NUMA Memory Management Through Modeling and Measurements

The class of NUMA (nonuniform memory access time) shared memory architectures is becoming increasingly important with the desire for larger scale multiprocessors. In such machines, the placement and movement of code and data are crucial to performance. The operating system can play a role in managing placement through the policies and mechanisms of the virtual memory subsystem. In this paper, w...

Simple but effective interventions in diabetes care.

n this issue of the MJA, there is important advice from expert bodies about basic management of diabetes and the investigation of kidney disease, which will inform the everyday care of patients. Cheung, the President of the Australian Diabetes Society, encourages us to individualise both the glycated haemoglobin (HbA1c) targets that we strive for in our patients and the choice of pharmacotherap...
