The goal of the Oracle JVM memory manager is to map Java memory management semantics (automatic memory management) to the Oracle database memory management framework.
It includes both a dynamic memory management stage, where the data types and virtual memory managers are defined, and a physical memory management stage, where the custom memory architecture is defined.
Today's designs use more than just different types of memory and include both memory management and memory protection units to partition and isolate the memory system.
Since a block size of 2 n along each dimension facilitates optimization and allows better memory management (aligned memory allocation), the choice of a 64 × 64 block size is a decent approximation.
Applying a configurable or programmable addressing circuitry capable of parallel memory accesses, the memory management of multimedia applications can be enhanced.
The results show that vertical elasticity, in the shape of dynamic memory management, enables to mitigate memory overprovisioning with controlled application performance penalty.
Object oriented languages such as C++ can use 20 times more memory than procedural languages like C. Bad memory management causes severe waste of memory, several times that actually needed, in programs.
ECP-C takes the programming abstractions described in real-time Java and reflects them into a C application system, providing extensions for multi-threading, resource sharing, memory management, external event, signaling, and memory access.
Optimizations incorporated include: (1) an efficient memory mapping and synchronization interface to minimize data movement, (2) multi-process sharing of the accelerator within a node to obtain balanced load with multicore processors, and (3) an automatic memory management system to efficiently utilize accelerator memory when sub-matrices spill over the limits of device memory.
