Introducing Amazon EC2 P2 Instances, the largest GPU-Powered virtual machine in the cloud

We are excited to announce the availability of P2 instances, a new instance type designed for compute-intensive applications that require high-performance GPU coprocessors and massive parallel floating point performance. P2 instances are ideal for deep learning, computational fluid dynamics, computational finance, seismic analysis, molecular modeling, genomics, and rendering workloads. For graphics workloads requiring DirectX and OpenGL, you can continue to use G2 instances.
