Meeting the performance, energy-efficiency, and resilience requirements 
of systems and applications at exascale will require rapid, accurate, 
and dynamic evaluation of tradeoffs. To provide these capabilities, 
significant advances in predictive modeling and simulation methods are 
needed. Models are key tools in the area of application/system 
co-design. As applications and systems evolve, models must be able to 
track ongoing complex changes and predict the impact of developments in 
both software and hardware design. While today's methods tend to focus 
on application performance as the metric of concern, modeling methods 
must evolve to consider performance, power consumption, and reliability 
in concert. It is critical to develop tools and techniques that will 
allow modeling capability to spread into the larger computational 
science community where it will have the greatest possible impact. 
Simulation and emulation capabilities must also expand along multiple 
directions, including scalability improvements, interoperability, 
support for exascale system design, and interfaces with modeling tools. 

As part of the process, we solicit community input, in the form of 
position papers that describe novel research approaches for performance 
modeling and simulation at extreme scales. Position papers should 
address one or more of the following areas. 

1. Development and generation of machine and application abstractions. 
Application developers need new abstract machine models that expose 
expected hardware features (e.g., SIMD, lightweight cores, or 
specialized functional units) and performance targets in terms of 
hierarchical parallelism, scale, data movement, computational intensity, 
bandwidths, latencies, and storage capacities of possible exascale 
configurations, as well as non-performance objectives such as power and 
resilience. Meanwhile, system architects need architecture-independent 
models of important applications that they can use to identify, 
understand, and evaluate application behavior on these proposed 
architectures. These abstractions must exist across the modeling, 
simulation, and measurement infrastructures. 

2. Dynamic and Actionable Modeling. Modeling and simulation techniques 
must provide predictive and optimization capabilities at runtime. This 
will require the development of rapid evaluation techniques as well as 
interfaces for incorporating models into the layers within the software 
stack. In addition to dynamic model creation, models must be actionable. 
That is, the models must enable appropriate levels of the software stack 
to react to the instantaneous state of the system, both hardware and 
software, and provide the necessary information that can be used to 
guide and optimize system operation. 

3. Standards, Integration, and Interoperability of ModSim Methodologies 
and Tools. ModSim components will be integrated in different layers of 
the exascale software stack and must be able to interoperate and 
leverage common infrastructure including aspects such as time 
progression mechanisms (e.g. in discrete-event generation), parameter 
sharing, component querying for internal data, and interfaces to dynamic 

The Organizing Committee will review these position papers and invite 
selected contributors to participate in the workshop to be held on 
September 4-5, 2013, in Seattle, WA. Responsive submissions will be made 
public via the workshop website and selected papers will be included in 
a post-workshop proceedings. 

Necessary background information, including previous workshop reports 
and submission instructions, can be found at 
http://hpc.pnl.gov/modsim/2013/, and submissions can be made with 
EasyChair at http://j.mp/modsim2013. 

Position papers (up to 2 pages) should describe a fundamental computer 
science research approach in the development of performance modeling and 
simulation approaches to address the key challenges associated with 
exascale computing systems. This description should be followed by a 
brief summary of related work and an assessment of the approach based on 
the following dimensions. 

1. Challenges addressed: Which exascale modeling and/or simulation 
challenges does this approach address? 

2. Maturity: What are the indicators that this approach will address the 
identified challenges? 

3. Uniqueness: To what extent is the proposed approach unique to 
exascale systems? Could it be addressed by other research programs? 

4. Novelty: How is this approach different from existing solutions? 

5. Applicability: To what extent will the proposed approach, if 
successful, be applicable to other areas? 

6. Effort: How much effort is needed to effectively explore this 

The paper may include any number of authors, but must provide contact 
information for a single "contact" author. There is no limit to the 
number of position papers that an individual or group can submit. 
Authors are strongly encouraged to follow the structure presented above. 
Authors of selected position papers will be invited to participate in a 
workshop based on the overall quality of the position paper(s) and our 
expectation that their inclusion in the workshop will stimulate 
constructive discussion by workshop participants. Unique positions that 
are well presented and emphasize transformative approaches will be given 

1. Length: Up to 2 pages (a list of cited references does not count 
against this limit). 

2. Due Date: June 3. Submission site: http://j.mp/modsim2013 

3. Notification of Selection for Workshop Presentation: June 21
