And also, many parallel system consists of network of workstation, the difference between Parallel DB & Distributed DB is becoming smaller. [Reference] 1. Great Paper on PDB&DDB Explanation Distributed and Parallel Database Systems 2. Great Paper by Jim Gray Parallel Database Systems 3. ...
In the last decade, research on database systems has focused on GPU co-processing to accelerate query engines [33,34,35,36]. GPUs, initially intended for image processing and parallel computations of vectorised data, also allow general-purpose computations (GPGPU). In the context of machine l...
Challenges for self-driving database systems, which tune their physical design and configuration autonomously, are manifold: Such systems have to anticipate future workloads, find robust configurations efficiently, and incorporate knowledge gained by previous actions into later decisions. We present a compo...
If tasks can run independently of one another, they can be distributed to different CPUs or nodes and there will be a scaleup: more processes will be able to run through the database in the same amount of time. If processes can run ten times faster, then the system can accomplish ten ...
The early 2000s saw the development of distributed computing, often involving multiple independent computers that could work on a task together, without shared memory. The early 2000s and onwards also saw an increase in the use of graphics processing units (GPUs), which consist of a large numbe...

To use RDMA, parallel database systems need to choose between message-passing mechanisms or shared memory abstractions for data transfer. Message-oriented communication is cooperative: The receiver initiates the communication and specifies a location in its memory space that will be changed; then the ...
I have now circled around to a class of problems that are not motivated by the shift to multicore but rather, like Web servers, have concurrency as core characteristics that must be addressed as part of the overall architecture of the application. Similar concerns apply to distributed application...
the Integrated Distributed Lock Manager (IDLM) component in the SGA, an area for global locks and resources. This area was formerly part of the external Distributed Lock Manager (DLM). Additional Information: For more information on Oracle8 database processes and memory structures, see Oracle8...
In recent years, inspired by the multisensory (visual and auditory) perception of the world by humans, research on classification methods has gradually shifted from unimodal to multi-modal domains28. Multimodal data fusion aims to combine different distributed and different types of data in a single...
