clOpenCL - Supporting Distributed Heterogeneous Computing in HPC Clusters [chapter]

Albano Alves, José Rufino, António Pina, Luís Paulo Santos
2013 Lecture Notes in Computer Science  
The former examples show that porting single-node-multi-GPU applications to a multi-node-multi-GPU execution environment is not straightforward.  ...  Thus, the benefits of a platform that would allow to efficiently run the same and unmodified program, whether in a single-node-multi-accelerator or a multi-nodemulti-accelerator scenario are obvious.  ...  An OpenCL application comprises a host program and a set of kernels intended to run on compute devices; the OpenCL specification defines a language for kernel programming, and an API for transferring data  ...
