After attending an Exascale presentation at this year's Linux
Foundation's Collaboration Summit, an interest was inspired in
establishing an understanding of the challenges in producing an
ExaFLOP cluster. To gain some perspective, the first question
was what happened in the growth from TeraFLOP to PetaFLOP
clusters. Looking back should help in looking forward and gives
a context for contrasting and comparing. The type of nodes
expected to be part of an ExaScale cluster are nodes built in
the future from the standard processors of that day. The node's
performance capability will be extrapolated based on Moore's
Law. It also assumes that no extreme measures will be undertaken
to modify the HPC applications to benefit from the performance.
The exception to this is the need to support a larger number of
CPUs and nodes. |Author||F. Michel Brown| |White Paper||The Road
