HPC 2013-14 | HPC strategies Te fourth dimension, HPC Usage

Expansion, is the one dedicated to the development and democratisation of HPC usage. Here we leave the purely technical realm to look at equally important actions, to do with the economy and education/training, among other things. Tese actions will require coordinated relationships with other players, with a view to developing the overall ecosystem mentioned earlier. First and foremost, it will be about

facilitating access to various levels of computing systems, promoting their use and optimising the costs of purchasing and ownership. In parallel, the SRA recommends stimulating the development of a services sector (porting, optimisation) which would be particularly useful for ISVs and industrial users, as well as supporting SMEs working on HPC technologies. Finally, it seems essential for all those

involved to contribute to HPC training and education, and training programmes focused on HPC usage are seen as equally important as those focused on HPC technology.

A detailed plan for shared funding In the production of the SRA, it seemed relevant to break down the technical aspects of the first three dimensions into six distinct sections, as shown in Figure 2. Te sections are HPC system components and architectures; system and management soſtware; programming environment; energy and resilience; balancing performance between computation, communications, storage; and big data and HPC usage models.

HPC usage models Including: big data, HPC in clouds

Based on this categorisation, each section is

subject to a more acurate analysis and is further broken down into sub-themes and research priorities with different milestones (Figure 3). A total of 140 milestones are proposed, as well as an overall plan linking them together, with two major phases: acquisition of the relevant technology capabilities in the various areas, with associated prototype demonstrators (2014-2017); and consolidation, extension, and exascale integration (2018-2020). Tis programme would be of little

use, however, without a concrete – and realistic – estimation of its costs. Excluding the prototypes, this will be around €150 million a year for seven years. Te European Commission will be approached to fund at

Energy and resiliency

Cooling and energy reuse

Energy-efficiency design of computer systems

System software and OS


Energy-efficient algorithms

Resilience and RAS

Balance compute, I/O and storage performance

I/O interfaces

Storage Hierarchy

Storage services

I/O system simulation

Interconnects and networks

Big data and HPC usage models

HPC as an instrument

HPC for big data


Industrial use of HPC as a commodity

The use of HPC in cloud environments

least half of this, if possible with a subsidy of more than 50 per cent, most notably for the SMEs involved. Te remaining funding will come from industry and research players who will underwrite associated projects and will be retained to carry them out. At the time of going to press, the

implementation of the programme has not been fully finalised. ETP4HPC’s message is that

“Undoubtedly, Europe has the resources in keeping with its ambitions. Now it has to work out how to mobilise them”

if the European Commission offers support at the level that is being proposed, the industry players will be able to commit to the proposed R&D programme, with performance indicators and monitoring mechanisms still to be defined along with the mechanisms for implementing the whole structure. In the face of likely developments on the other side of the Atlantic and the growing power of China, this is no small challenge. Undoubtedly, Europe has the resources in keeping with its ambitions. Now it has to work out how to mobilise them. l
