The modern manycore coprocessors and GPUs demonstrate very high performance on certain problems. Recent research has shown that these coprocessors can be used to accelerate database operations. But, to the best of our knowledge, there is only a little prior work on using coprocessors in multiprocessor database systems. This paper focuses on evaluation of database multiprocessor architectures with manycore coprocessors and GPUs. We implemented the emulator of parallel DBMS that uses computing cluster with NVIDIA GPUs or Intel Xeon Phi coprocessors for relational query processing. It allows to simulate simple SELECT and JOIN queries. A number of experiments have been done using this emulator. These experiments have shown that coprocessors are less efficient than CPUs for processing modeled SELECT queries, but more efficient than CPUs for processing INNER JOIN queries.

Free GPU computing nodes at hgpu.org

Registered users can now run their OpenCL application at hgpu.org. We provide 1 minute of computer time per each run on two nodes with two AMD and one nVidia graphics processing units, correspondingly. There are no restrictions on the number of starts.

The platforms are

Node 1
  • GPU device 0: AMD/ATI Radeon HD 5870 2GB, 850MHz
  • GPU device 1: AMD/ATI Radeon HD 6970 2GB, 880MHz
  • CPU: AMD Phenom II X6 @ 2.8GHz 1055T
  • RAM: 12GB
  • OS: OpenSUSE 13.1
  • SDK: AMD APP SDK 2.9
Node 2
  • GPU device 0: AMD/ATI Radeon HD 7970 3GB, 1000MHz
  • GPU device 1: nVidia GeForce GTX 560 Ti 2GB, 822MHz
  • CPU: Intel Core i7-2600 @ 3.4GHz
  • RAM: 16GB
  • OS: OpenSUSE 12.2
  • SDK: nVidia CUDA Toolkit 6.0.1, AMD APP SDK 2.9

Completed OpenCL project should be uploaded via User dashboard (see instructions and example there), compilation and execution terminal output logs will be provided to the user.

The information send to hgpu.org will be treated according to our Privacy Policy
