£313 million collaboration to boost Big Data research in the UK

The research programme will leverage OpenPOWER high performance computing

innovations to enable complex analytics on massive amounts of data.

IBM contributions

• Latest data-centric and cognitive computing technologies,

including ‘Watson’ cognitive computing platform

• 24 IBM researchers to be based at the Hartree Centre

• Joint commercialisation of intellectual property produced in

partnership with STFC

https://www.stfc.ac.uk/3583.aspx


• In-memory distributed database using GPUs for processing

• Order of magnitude gains:

• Performance over CPU solutions

• Power reduction

• Cost savings

• Anticipate order of magnitude gains with POWER based NVLink solutions in 2016

GPUdb in-memory Accelerated Database

Ultrafast ingest and analysis of billions of objects

CORAL: Built for Grand Scientific Challenges

Fusion EnergyRole of material disorder, statistics, and fluctuations in nanoscale materials and systems.

CombustionCombustion simulations to enable the next gen diesel/bio- fuels to burn more efficiently

Climate Change Study climate change adaptation and mitigation scenarios; realistically represent detailed features

Nuclear EnergyUnprecedented high-fidelity radiation transport calculations for nuclear energy applications

BiofuelsSearch for renewable and more efficient energy sources

AstrophysicsRadiation transport – critical to astrophysics, laser fusion, atmospheric dynamics, and medical imaging


Profile Existing Code(x86 + GPU)

Build on Power

Profile New Code

(Power + GPU)

Tune for Power + GPU

“Ported”

Explicit architecture

dependencies must be

resolved!When are we “done”?

Take advantage of different

performance ratios between

the systems

Many years of tuning in one

environment can result in

implicit performance

dependencies.

Currently targeting 66 codes

for GPU & Power

40 codes ported

26 codes in process

Power & GPU Scientific Applications Status

Power only – 113 ported, 58 in process


Going back to that “done” question…

Limiter FLOPS Memory IO

Parallel = = =

Expectations P8 & K80 vs

other GPU accelerated systems

Limiter FLOPS Memory IO

Serial = ++ ++

Parallel >= >= ++

• GPUs are identical, with very similar IO

• Amortizing PCIe transfer constrains

exploitable parallelism

• Overall expectation is for broadly similar

performance today

• GPUs are identical, but NVLINK is a ++

• Lower NVLINK transport penalty means

easier to offload FLOPs to GPU

• Overall expectation is for improved

performance tomorrow

Observed results tracking these expectations well

Expectations P8+ & Pascal vs

other GPU accelerated systems
