Supporting future applications like gestural interfaces on low-power platforms such as cell phones and tablets forces developers to provide high compute bandwidth with low latency. To this end, PTask is a dataflow programming framework for GPUs that insulates the programmer from low-level details such as device-management, data transfer, and asynchrony. PTask is supported at the system call interface, so the OS can provide isolation and fairness guarantees for GPU computations.
