Abstract
| Many domains such as scientific computing and neuroscience require
end users to compose heterogeneous computational entities to automate their professional
tasks. However, an issue that frequently hampers such composition is
data-mismatches between computational entities. Although, many composition
frameworks today provide support for data mismatch resolution through specialpurpose
data converters, end users still have to put significant effort in dealing
with data mismatches, e.g., identifying the available converters and determining
which of them meet their QoS expectations. In this paper we present an approach
that eliminates this effort by automating the detection and resolution of data mismatches.
Specifically, it uses architectural abstractions to automatically detect
different types of data mismatches, model-generation techniques to fix those mismatches,
and utility theory to decide the best fix based on QoS constraints. We
illustrate our approach in the neuroscience domain where data-mismatches can
be fixed in an efficient manner on the order of few seconds. |
