> Greetings, everyone.
> 
> It's my pleasure to announce a talk by Prof Babak Falsafi of EPFL
> (formerly of CMU), renowned computer architect. Babak will speak in
> MPEB 6.12 at 2 PM on Tuesday, the 4th of February.
> 
> Let me emphasize that no matter the area of CS you work in, this is a
> talk you should find relevant and interesting.
> 
> Computer architecture is hugely important to the work of practically
> every computer scientist, as it dictates what the CPUs we all use look
> like (and thus what algorithms need to look like). For decades,
> computer architects devised ingenious techniques for increasing CPU
> clock speeds and extracting ever greater performance from the same
> sequential programs. They then determined that clock speed increases
> could not be sustained any longer because of fundamental limits on
> heat dissipation. Thus began the era of multi-core CPUs, which offer
> increased parallelism, but not clock-rate increases. That shift has
> required rethinking algorithms and data structures, compilers, OS
> kernels, memory consistency models, and even debugging and testing,
> among other areas.
> 
> Babak will speak on the next round of scaling limitations that future
> server-class CPUs will encounter, and how those limitations will
> change the way CPUs look, including his own creative work on how to
> ensure that future CPUs continue to offer performance increases
> despite these limitations.
> 
> He will target his talk to a general CS audience--he will not be
> assuming specialist knowledge of computer architecture.
> 
> All very strongly encouraged to attend. Again, this a topic that
> undergirds what all of us do!

> Abstract:
> 
> Information technology is now an indispensable pillar of a modern-day
> society, thanks to the proliferation of digital platforms in the past
> several decades. We are now witnessing two inflection points, however,
> that are about to change IT as we know it. First, we are entering the
> Big Data era where demand for robust and economical data processing,
> communication and storage is growing faster than technology can
> sustain. Second, while forecasts indicate that chip density scaling
> will continue for another decade, the diminishing returns in supply
> voltage scaling and the impending "energy wall" are leading server
> designers towards energy-centric solutions, and ultimately Dark
> Silicon. In this talk, I will motivate these two IT trends and present
> promising research avenues for server chip design including
> specialized scale-out processors, on-chip networks and die-stacked
> DRAM cache hierarchies.
> 
> Bio:
> 
> Babak is Professor in the School of Computer and Communication
> Sciences and the founding director of the EcoCloud research center
> pioneering future energy-efficient and environmentally-friendly cloud
> technologies at EPFL. He has made numerous contributions to computer
> system design and evaluation including a scalable multiprocessor
> architecture which was prototyped by Sun Microsystems (now Oracle),
> snoop filters and temporal stream prefetchers that are incorporated
> into IBM BlueGene/P and BlueGene/Q, and computer system simulation
> sampling methodologies that have been in use by AMD and HP for
> research and product development. His most notable contribution has
> been to be first to show that contrary to conventional wisdom,
> multiprocessor memory programming models -- known as memory
> consistency models -- prevalent in all modern systems are neither
> necessary nor sufficient to achieve high performance. He is a
> recipient of an NSF CAREER award, IBM Faculty Partnership Awards, and
> an Alfred P. Sloan Research Fellowship. He is a fellow of IEEE.
