The document discusses the MODELS project which aims to develop a unified modeling environment for designing parallel applications and heterogeneous platforms. It summarizes the goals of increasing design abstraction levels and expressing parallelism. It then outlines the Eurostars MODELS consortium partners and goals of each work package, which include system modeling tools, design space exploration, and validation of the unified environment.

12. #OSSPARIS16
• Current limitations at high-abstraction levels
• Parallelism is not expressed at high abstraction levels
– Application Parallelism: Task and Data Parallelism?
– Execution Platform Parallelism: How to express many cores of an execution
platform, i.e. 64 cores of a platform?
Modelio in MODELS Project

13. #OSSPARIS16
• Current limitations in existing projects and tools/environments:
– No single environment or design tool present that spans all design levels: high-
level modeling, IP-reuse, design space exploration, platform independence,
automatic verification/validation, etc.
– Existing High-Level Synthesis (HLS) tools are usually tied to specific execution
platforms
MODELS Project

14. #OSSPARIS16
• Model will provide
– A platform-independent design framework and unified environment for next-
generation parallel computing platforms.
– Model definition at different abstraction levels for high-level synthesis, automatic
validation, IP reuse and design space exploration.
– Targeted dataflow applications: signal processing, video compression, 3D medical
image processing, etc.

20. #OSSPARIS16
• MODELS RSM subset main concepts:
– Shaped: A concept that allows to define multiplicity of an element, i.e. no. of times the
element is repeated.
• For e.g. instead of modeling 64 instances of a core, we can model one instance and have a
shaped value of 64
• Can be used for multi-dimensional layout: i.e. 4x4.
– Distribute: A type of Allocation dependency
• Allows to determine which instance of source (application) is mapped to which instance of target
(platform)
– Reshape: A type of connection
• Similar to distribute, allows to connect a source instance to a target instance when either one or
both (source/target) have a shaped value.
