Re: Amazon EC2 Configuration for GPU Instance

Hi Kees,

Most of them are virtual machines on headless systems.. except the one
that Pete was using! The blurb on the AWS site says:-

'G2

This family includes G2 instances intended for graphics and general
purpose GPU compute applications.

Features:

High Frequency Intel Xeon E5-2670 (Sandy Bridge) Processors
High-performance NVIDIA GPU with 1,536 CUDA cores and 4GB of video memory
On-board hardware video encoder designed to support up to eight
real-time HD video streams (720p@30fps) or up to four real-time FHD
video streams (1080p at 30 fps).
Support for low-latency frame capture and encoding for either the full
operating system or select render targets, enabling high-quality
interactive streaming experiences.'

He said it gets about 420 Mk/sec. I am looking forward to when they
offer AMD based systems :)

Kind regards,
Mike
