Chap2. Heterogeneous data parallel computing The structure of a CUDA C program reflects the coexistence of a host (CPU) and one or more devices (GPUs) in the computer. Each CUDA C source file can have a mixture of host code and device code. By default, any traditional C program is a CUDA program that contains only host code. One can add device code into any source file. The device code is clear..

Xen and the Art of Virtualization Abstraction Numerous systems have been designed which use virtualization to subdivide the ample resources of a modern computer. Some require specialized hardware, or cannot support commodity operating systems. Some target 100% binary compatibility at the expense of performance. Others sacrifice security or functionality for speed. Few offer resource isolation or..
