Recent technologies have brought parallel infrastructure to general users. Nowa-days parallel infrastructure is available in PC’s and personal laptops. Now single core machines have became history. Even multi-core technologies are replaced by GPGPUs when it comes to high performance computing because GPGPUs are giv-ing many cores at low cost. Sequential programs of the past are unable to efficiently utilize this parallel architecture. An application which run parallel has lesser running time than sequential application. Writing parallel programs manually is a difficult task. So we can not expect domain experts to write parallel programs. We can create an automatic parallelizing compiler to convert a sequential code to parallel code. Domain experts can use this kind of compiler to convert their sequential code to parallel code to utilize parallel infrastructure. In this work, we have proposed a tool which will convert a sequential code to parallel code. Here for sequential code we took LINQ programming language and for parallel architecture we took CUDA. LINQ is a query language developed by Microsoft to query data in .NET Languages and CUDA is an architecture developed by NVIDIA to use GPUs. Our proposed parallelizing compiler will automatically convert a LINQ code to an equivalent CUDA code. Microsoft has also developed a compiler to parallelize LINQ operators but it is only for multi-cores and not for GPGPUs. In our work we are parallelizing these LINQ operators in GPGPUs using CUDA.

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: nVidia GeForce GTX 560 Ti 2GB, 822MHz
  • 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: nVidia CUDA Toolkit 6.5.14, AMD APP SDK 3.0
Node 2
  • GPU device 0: AMD/ATI Radeon HD 7970 3GB, 1000MHz
  • GPU device 1: AMD/ATI Radeon HD 5870 2GB, 850MHz
  • CPU: Intel Core i7-2600 @ 3.4GHz
  • RAM: 16GB
  • OS: OpenSUSE 12.3
  • SDK: AMD APP SDK 3.0

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
