  Power efficiency is becoming an ever more important metric for both high
performance and high throughput computing. Over the course of next decade it is
expected that flops/watt will be a major driver for the evolution of computer
architecture. Servers with large numbers of ARM processors, already ubiquitous
in mobile computing, are a promising alternative to traditional x86-64
computing. We present the results of our initial investigations into the use of
ARM processors for scientific computing applications. In particular we report
the results from our work with a current generation ARMv7 development board to
explore ARM-specific issues regarding the software development environment,
operating system, performance benchmarks and issues for porting High Energy
Physics software.
