memory contention

[′mem·rē kən′ten·chən]
(computer science)
A situation in which two different programs, or two parts of a program, try to read items in the same block of memory at the same time.

5GB limit on D3 virtual memory, the per-process memory limit imposed by a 32-bit application and true 64-bit provide for improved process performance, larger memory resident dataset, reduced memory contention, and enhanced overall system performance," explained John Bramley, Lab Business Area executive at Rocket Software.
Memory Contention -- Multiple threads try to access memory at the same time.
Linear speedup is not entirely achieved because of memory contention, that is, concurrent accesses to different data structures in the same memory modules.
We believe that the degradation is due to (1) memory contention as the disks transfer data to memory, (2) preemption of the file system and application threads due to disk interrupts, and (3) contention for kernel data structures such as the ready queues.
Using a traditional Harvard architecture, it features separate local, tightly coupled, instruction and data RAMs to eliminate memory contention and provide fast performance on performance-critical code and interrupt handling routines.

6 provides support across the spectrum of embedded needs as well as enhancements in the general areas of determinism, reduced memory contention, and the leveraging of POSIX for thread creation and management and task scheduling.
OctigaBay has been developing a high performance computing (HPC) system designed around its direct connected processor architecture, an innovative approach to massively parallel processing that directly links together processors, alleviating memory contention and interconnect bottlenecks found in cluster systems.
A+OpenTune/Storage Edition can measure the CPU and memory utilization, I/O transfer rates, and uncover disk bottlenecks, to easily identify system problems such as runaway processes consuming excessive CPU resources, disk "hot spots," and system slowdowns due to memory contention.
