Kernel Weaver: Automatically Fusing Database Primitives for Efficient GPU Computation
2012
2012 45th Annual IEEE/ACM International Symposium on Microarchitecture
Preserved Fulltext
Based on this classification, we propose a compiler framework, Kernel Weaver, that can automatically fuse relational algebra operators thereby eliminating redundant data movement. ...
Kernel fusion fuses the code bodies of two GPU kernels to i) reduce data footprint to cut down data movement throughout GPU and CPU memory hierarchy, and ii) enlarge compiler optimization scope. ...
First there is a need for the efficient GPU implementations of RA primitives. ...

, query parallelization techniques used by analytical database engines are designed for homogeneous multicore servers, where query plans are parallelized across CPUs to process data stored in cache coherent ...
In doing so, we show that efficiently exploiting CPU-GPU parallelism can provide 2.8x and 6.4x improvement in performance compared to state-of-the-art CPU-based and GPU-based DBMS. ...
Kernel Weaver [35] is a compiler that automatically tries to fuse multiple relational operations together into a single kernel, in order to i) reduce data movement and ii) enable additional compiler ...

Our goal is to bring efficient, object-oriented programming to massively parallel SIMD architectures, especially GPUs. ...
Object-oriented programming is often regarded as too inefficient for high-performance computing (HPC), despite the fact that many important HPC problems have an inherent object structure. ...
For example, Harlan [84] supports nested kernels, Futhark [82] has support for nested parallelism and a powerful fusion engine for map/reduce combinations, and Kernel Weaver focuses on database queries ...
