How do we go from “here” to “there”? A

(possible) view of tomorrow’s HENP

computing

As the High Energy and Nuclear Physics (HENP) communities are

progressing toward a hardening of their data production environment,

the ever-changing world of computing is bombarding us with new

trends and new paradigms with potentials to dramatically change the

landscape of tomorrow’s computing. From the explosion of new

processor architectures and devices often mixing CPU and powerful

graphics cards, the onset of the multi-core era to the appearance of

the so-called Cloud computing (challenging the existence of Grid

computing), the “buzz” are numerous. But what are the technologies

with a real changing power able to affect today’s HENP HTC & HPC

worlds? What are the challenges for our HENP communities to truly

harvest the power of those new technologies? Are we ready for this

rapid evolution and where do we go from here to “there”? We will

attempt to present a broad overview of the issues and investigate

those questions through a few illustrative examples.
