“…In the Invasive Computing project, we implemented the actor model using the FunState model, which emphasizes clearly defined communication channels between the different actors [1]. The resulting library, actorX10 [13], implements this model in a distributed memory environment (X10-based APGAS). In [13] and [14], we showed that this approach can be used for applications in HPC as well, by implementing a tsunami simulation proxy application, SWE-X10.…”

Programmability is one of the key challenges of Exascale Computing. Using the actor model for distributed computations may be one solution. The actor model separates computation from communication while still enabling their overlap. Each actor possesses specified communication endpoints to publish and receive information. Computations are undertaken based on the data available on these channels. We present a library that implements this programming model using UPC++, a PGAS library, and evaluate three different parallelization strategies, one based on rank-sequential execution, one based on multiple threads in a rank, and one based on OpenMP tasks. In an evaluation of our library using shallow water proxy applications, our solution compares favorably against an earlier implementation based on X10, and a BSP-based approach.

“…This is a modern parallel programming language to program scalable multi-core systems due to the support of partitioned global address space (PGAS). Our implemented actor library, called actorX10 [20], enables to implement formal actor models as exemplified in Script 1. First, the actors belonging to an application are declared (line 3-6), and then the actor graph is built (line 18) by adding all actors (lines 21-23) and connecting their inputs and outputs to realize the channels (lines [25][26][27][28].…”

Multi-Processor Systems-on-a-Chip (MPSoCs) provide sufficient computing power for many applications in scientific as well as embedded applications. Unfortunately, when real-time requirements need to be guaranteed, applications suffer from the interference with other applications, uncertainty of dynamic workload and state of the hardware. Composable application/architecture design and timing analysis is therefore a must for guaranteeing real-time applications to satisfy their timing requirements independent from dynamic workload. Here, Invasive Computing is used as the key enabler for compositional timing analysis on MPSoCs, as it provides the required isolation of resources allocated to each application. On the basis of this paradigm, this work proposes a hybrid application mapping methodology that combines designtime analysis of application mappings with run-time management. Design space exploration delivers several resource reservation configurations with verified real-time guarantees for individual applications. These timing properties can then be guaranteed at run-time, as long as dynamic resource allocations comply with the offline analyzed resource configurations. This article describes our methodology and presents programming, optimization, analysis, and hardware techniques for enforcing timing predictability. A case study illustrates the timing-predictable management of real-time computer vision applications in dynamic robot system scenarios.

“…We use the actor model and the ActorX10 library described in Roloff et al (2016). We subdivide the simulation domain, represented by a two-dimensional array of unknowns for h, hu, hv and b, into equally sized, rectangular patches and assign one actor to every patch.…”

We present an X10 software package for the solution of the shallow water equations, a set of equations commonly used to simulate tsunami and flooding events. The software uses an actor-oriented approach to obtain a communication scheme that does not rely on central coordination. Instead, each actor only communicates with its neighbors. We evaluated the package via scaling tests on singleplace shared memory as well as multi-place distributed memory system configurations, and found it to perform comparably to prior implementations based on C++, OpenMP and MPI.
