= Parallel DBMS is for: - High Performance - High Availability But both PDB&DDB need to consider the following problems: 1. Data Distribution (Placement & Replicatioin); 2. Query Parallelization(Distributed Evaluation). And also, many parallel system consists of network of workstation, the diff...
In this paper, we propose an operator fusion method based on GPU-accelerated linear algebraic evaluation of relational queries. Our method leverages linear algebra computation properties to merge operators in machine learning predictions and data processing, significantly accelerating predictive pipelines by ...

Query optimization for sequential execution of non-recursive queries has reached a high level of sophistication in commercial DBMS. The successful application of parallel processing for the evaluation of recursive queries will require a ... T Zurek,P Thanisch - Springer-Verlag 被引量: 4发表: 1995...
Graph partitioning has long been seen as a viable approach to addressing Graph DBMS scalability. A partitioning, however, may introduce extra query processing latency unless it is sensitive to a specific query workload, and optimised to minimiseinter-partition traversals for that workload. Additionally...
We use the modulo function in repartitioning data during query evaluation. We pre-project all unused columns as a column-store database would. We choose TPC-H queries Q3, Q4, and Q10 for the evaluation due to their data access locality [7]. The join operations in the queries are ...

In our evaluation, automatic differentiation accelerated the runtime by the number of cached subexpressions compared to compiling each derivative separately. Our GPU kernels with independent models allowed maximal throughput even for small...

Rather than evaluate the parallel operations as they are traversed when the data parallel pipeline is executed, the evaluator306defers the evaluation of parallel operations. Instead, the evaluator306constructs an internal execution plan dataflow graph that contains the operations and their arguments. Once...
