Speaker
Mr
Sverre Jarp
(CERN)
Description
This talk will start by reminding the audience that Moore's law is very much alive (even after 40+ years of existence).
Transistors will continue to double for every new silicon generation every other year.
Chip designers are therefore trying every possible "trick" for putting the transistors to good use.
The most notable one is to push more parallelism into each CPU: More and longer vectors, more parallel execution units,
more cores and more hyperthreading inside each core. In addition highly parallel grphics processing units (GPUs) are
also entering the game and compete efficiently with CPUs in several computing fields.
The speaker will try to predict the CPU dimensions we will reach during the LHC era, based on what we have seen in the recent past and the projected roadmap for silicon.
He will also discuss the impact on HEP software.
Can we continue to rely on event-level parallelism at the process levels or do we need to move to a new software paradigm?
