8.12 Most systems allow a program to allocate more memory to its address space during execution. Allocation of data in the heap segments of programs is an example of such allocated memory. What is required to s
In the figure, allocation of tasks to threads are color-coded. Note that the G-threads will request tasks more often than the C-threads as GPUs make the calculations faster than a single CPU core. Moreover, faster GPUs will be assigned work more frequently than modest GPUs. Show moreView...
These trends of computer architecture trigger to rethink the internal structures and policies of today's operating system. In this paper, we design a new memory-aware CPU allocation policy for multicore NUMA architectures that has the following three features. First, it makes a CPU allocation ...
Memory Controller—This can be as simple as just an interface to some DRAM, or it can include a cache manager performing cache space allocation and cache lookup. Cache is an important subject and will be covered in Chapter 22,“The Cache Layer.” Host Interface—This is the physical link ...
Some systems support dynamic memory allocation, where memory banks can be dynamically assigned or reconfigured based on changing workload requirements. This flexibility allows for efficient utilization of memory resources and optimization of system performance in real-time. ...

The basic idea here is to delay the allocation of the freed memory region so that any immediate access to it after it has been freed can be detected. Naturally, the size of this quarantine region needs to be limited, otherwise it will result in significant memory pressure. Based on this,...
A method, system, and computer program product for profiling memory allocation in a data processing system are disclosed. The method includes initiating a memory allocation request and, in response to the memory allocation request, profiling the memory allocation request to determine a prescribed set ...
