Sample: simpleMultiCopy
Minimum spec: SM 1.1

Supported in GPUs with Compute Capability 1.1, overlapping compute with one memcopy is possible from the host system.  For Quadro and Tesla GPUs with Compute Capability 2.0, a second overlapped copy operation in either direction at full speed is possible (PCI-e is symmetric).  This sample illustrates the usage of CUDA streams to achieve overlapping of kernel execution with data copies to and
