abstract = {Today’s supercomputers gain their performance through a
rapidly increasingnumber of cores per node. To tackle issues
arising from those developmentsnew parallelization
approaches guided by modern software engineering are
in-evitable. The concept of task-based parallelization is a
promising candidate toovercome many of those challenges.
However, for latency-critical applications,like molecular
dynamics, available tasking frameworks introduce
considerableoverheads. In this work a lightweight task
engine for latency-critical applica-tions is proposed. The
main contributions of this thesis are a static
data-flowdispatcher, a type-driven priority scheduler and an
extension for communication-enabled tasks. The dispatcher
allows a user-configurable mapping of
algorithmicdependencies in the task-engine at compile-time.
Resolving these dependenciesat compile-time reduces the
run-time overhead. The scheduler enables the pri-oritized
execution of a critical path of an algorithm. Additionally,
the prioritiesare deduced from the task type at compile-time
as well. Furthermore, the afore-mentioned task engine
supports inter-node communication via message passing.The
provided communication interface drastically simplifies the
user interface ofinter-node communication without
introducing additional performance
penalties.Thisisonlypossiblebydistinguishingtwodeveloperroles–thelibrarydeveloperand
the algorithm developer. All proposed components follow a
strict guideline toincrease the maintainability for library
developers and the usability for algorithmdevelopers. To
reach this goal a high level of abstraction and
encapsulation isrequired in the software stack. As proof of
concept the communication-enabledtask engine is utilized to
parallelize the FMM for molecular dynamics.},
