Abstract
With the surge of multi- and manycores, much research has focused on algorithms for mapping and scheduling on these complex platforms. Large classes of these algorithms face scalability problems. This is why diverse methods are commonly used for reducing the search space. While most such approaches leverage the inherent symmetry of architectures and applications, they do it in a problem-specific and intuitive way. However, intuitive approaches become impractical with growing hardware complexity, like Network-on-Chip interconnect or heterogeneous cores. In this paper, we present a formal framework that can determine the inherent symmetry of architectures and applications algorithmically and leverage these for problems in software synthesis. Our approach is based on the mathematical theory of groups and a generalization called inverse semigroups. We evaluate our approach in two state-of-the-art mapping frameworks. Even for the platforms with a handful of cores of today and moderate-size benchmarks, our approach consistently yields reductions of the overall execution time of algorithms, accelerating them by a factor up to 10 in our experiments, or improving the quality of the results.

Abstract
Technological advances drive hardware to ever smaller feature sizes, causing devices to become more vulnerable to faults. Applications can be protected against errors resulting from faults by adding error detection and recovery measures in software. This is popularly achieved by applying automatic program transformations. However, transformations applied to intermediate program representations are fundamentally incapable of protecting against vulnerabilities that are introduced during compilation. In particular, the compiler backend may introduce additional memory accesses. This report presents an extended compiler backend that protects these accesses against faults in the memory system. It is demonstrated that this enables the detection of all single bit flips in memory. On a subset of SPEC CINT2006 the runtime overhead caused by the extended backend amounts to 1.50x for the 32-bit processor architecture i386, and 1.13x for the 64-bit architecture x86 64.

Abstract
The use of heterogeneous Multi-Processor System-on-Chip (MPSoC) is a widely accepted solution to address the increasing demands on high performance and energy efficiency for modern embedded devices. To enable the full potential of these platforms, new tools are needed to tackle the programming complexity of MPSoCs, while allowing for high productivity. This chapter discusses the MPSoC Application Programming Studio (MAPS), a framework that provides facilities for expressing parallelism and tool flows for parallelization, mapping/scheduling, and code generation for heterogeneous MPSoCs. Two case studies of the use of MAPS in commercial environments are presented. This chapter closes by discussing early experiences of transferring the MAPS technology into Silexica GmbH, a start-up company that provides multi-core programming tools.

Abstract
State-of-the-art DRAM cache employs a small Tag-Cache and its performance is dependent upon two important parameters namely bank-level-parallelism and Tag-Cache hit rate. These parameters depend upon the row buffer organization. Recently, it has been shown that a small row buffer organization delivers better performance via improved bank-level-parallelism than the traditional large row buffer organization along with energy benefits. However, small row buffers do not fully exploit the temporal locality of tag accesses, leading to reduced Tag- Cache hit rates. As a result, the DRAM cache needs to be re-designed for small row buffer organization to achieve additional performance benefits. In this paper, we propose a novel tag-store mechanism that improves the Tag-Cache hit rate by 70% compared to existing DRAM tag-store mechanisms employing small row buffer organization. In addition, we enhance the DRAM cache controller with novel policies that take into account the locality characteristics of cache accesses. We evaluate our novel tag-store mechanism and controller policies in an 8-core system running the SPEC2006 benchmark and compare their performance and energy consumption against recent proposals. Our architecture improves the average performance by 21.2% and 11.4% respectively compared to large and small row buffer organizations via simultaneously improving both parameters. Compared to DRAM cache with large row buffer organization, we report an energy improvement of 62%.

Abstract
Errors in memory are known to be a major cause of system failures. Moreover, it has recently been found that single-error correcting, double-error detecting (SECDED) codes, which are widely used in ECC memory modules, are incapable of handling large fractions of errors that occur in practice. This calls for more powerful error detection measures. However, the higher the number of bit flips that can still be detected as an error, the larger the memory overhead. Cost considerations and the varying needs for reliability of different applications may not always warrant laying down extra hardware to accommodate overheads. Software-implemented error detection offers a flexible alternative. In this work we propose the software-implemented flexMEDiC scheme for detecting errors in the memory system, including main memory, on-chip caches, and load-store queues. It is shown that single and double bit flips are detected by flexMEDiC, and evidence is given that suggests that up to five bit flips within a single data word can still be detected as errors. The average runtime overhead incurred by flexMEDiC is 1.55x.

Abstract
Domain-specific languages (DSLs) are of increasing importance in scientific high-performance computing to reduce development costs, raise the level of abstraction and, thus, ease scientific programming. However, designing and implementing DSLs is not an easy task, as it requires knowledge of the application domain and experience in language engineering and compilers. Consequently, many DSLs follow a weak approach using macros or text generators, which lack many of the features that make a DSL a comfortable for programmers. Some of these features—e.g., syntax highlighting, type inference, error reporting, and code completion—are easily provided by language workbenches, which combine language engineering techniques and tools in a common ecosystem. In this paper, we present the Parallel Particle-Mesh Environment (PPME), a DSL and development environment for numerical simulations based on particle methods and hybrid particle-mesh methods. PPME uses the meta programming system (MPS), a projectional language workbench. PPME is the successor of the Parallel Particle-Mesh Language (PPML), a Fortran-based DSL that used conventional implementation strategies. We analyze and compare both languages and demonstrate how the programmer s experience can be improved using static analyses and projectional editing. Furthermore, we present an explicit domain model for particle abstractions and the first formal type system for particle methods.

Abstract
Future systems based on post-CMOS technologies will be wildly heterogeneous, with properties largely unknown today. This paper presents our design of a new hardware/software stack to address the challenge of preparing software development for such systems. It combines well-understood technologies from different areas, e.g., network-on-chips, capability operating systems, flexible programming models and model checking. We describe our approach and provide details on key technologies.

Abstract
Software abstractions are crucial to effectively program heterogeneous Multi-Processor Systems on Chip (MPSoCs). Prime examples of such abstractions are Kahn Process Networks (KPNs) and execution traces. When modeling computation as a KPN, one of the key challenges is to obtain a good mapping, i.e., an assignment of logical computation and communication to physical resources. In this paper we compare two system-level frameworks for solving the mapping problem: Sesame and MAPS. These frameworks, while superficially similar, embody different approaches. Sesame, motivated by modeling and design-space exploration, uses evolutionary algorithms for mapping. MAPS, being a compiler framework, uses simple and fast heuristics instead. In this work we highlight the value of common abstractions, such as KPNs and traces, as a vehicle to enable comparisons between large independent frameworks. These types of comparisons are fundamental for advancing research in the area. At the same time, we illustrate how the lack of formalized models at the hardware level are an obstacle to achieving fair comparisons. Additionally, using a set of applications from the embedded systems domain, we observe that genetic algorithms tend to outperform heuristics by a factor between 1x and 5x, with notable exceptions. This performance comes at the cost of a longer computation time, between 0 and 2 orders of magnitude in our experiments.

Abstract
In deeply embedded heterogeneous multicores the allocation of data to memories is crucial for application performance. For applications with stringent throughput constraints, the allocation is often done manually by carefully assigning static memory locations to the logical buffers of the application. Today, designers are confronted with applications with thousands of buffers and architectures with hundreds of memories, rendering manual approaches impractical. In this paper we present an automatic approach for statically allocating logical buffers to physical memories, assuming a fixed task-to-processor mapping and respecting multiple throughput constraints. In our approach, we model the application in a data-centric way, by explicitly defining buffers and associating computational tasks that access the buffers within well-specified time intervals. Besides, we use an architecture model that allows to perform an allocation that is aware of the topology of the multicore and the physical bandwidth constraints of the interconnect. We present a layered approach to describe and solve the buffer-allocation problem as well as related subproblems, using mixed-integer linear pro- gramming. We show that the buffer-allocation problem is NP-complete, and present a more scalable formulation as a semi-definite programming problem. We evaluate the proposed LP methods by allocating around 1000 buffers corresponding to processing one frame in the Long-Term Evolution (LTE) standard, onto a multicore with 80 processing elements. We introduce a solution approach that allowed to find an optimal allocation in around 2 hours, which is at least two orders of magnitude faster than a straightforward formulation.

We present a layered approach to describe and solve the buffer-allocation problem as well as related subproblems, using mixed-integer linear pro- gramming. We show that the buffer-allocation problem is NP-complete, and present a more scalable formulation as a semi-definite programming problem. We evaluate the proposed LP methods by allocating around 1000 buffers corresponding to processing one frame in the Long-Term Evolution (LTE) standard, onto a multicore with 80 processing elements. We introduce a solution approach that allowed to find an optimal allocation in around 2 hours, which is at least two orders of magnitude faster than a straightforward formulation.}

Abstract
Programming models based on dataflow or process networks are a good match for streaming applications, common in the signal processing, multimedia and automotive domains. In such models, parallelism is expressed explicitly which makes them well-suited for programming parallel machines. Since today s applications are no longer static, expressive programming models are needed, such as those based on Kahn Process Networks (KPNs). In these models, tasks cannot be handled as black boxes, but have to be analyzed, profiled and traced to characterize their behavior. This is especially important in the case of heterogenous platforms with many processors of multiple different types. This presentation describes a tool flow to handle KPN applications and gives insights into mapping algorithms for heterogeneous platforms.

Abstract
This tutorial talk starts by introducing new types of heterogeneous systems and their challenges for hardware/software programming stacks. These systems are currently being investigated in the context of the German cluster of excellence Cfaed – Center for Advancing Electronics Dresden . We will then look at dataflow modeling concepts, with emphasis on the dynamic models that are needed to express today s changing workloads. Finally, the talk will introduce methods and algorithms for mapping sets of applications modeled in this way to heterogeneous systems.

Abstract
In recent years, architectures combining a reconfigurable fabric and a general purpose processor on a single chip became increasingly popular. Such hybrid architectures allow extending embedded software with application specific hardware accelerators to improve performance and/or energy efficiency. Aiding system designers and programmers at handling the complexity of the required process of hardware/software (HW/SW) partitioning is an important issue. Current methods are often restricted, either to bare-metal systems, to subsets of mainstream programming languages, or require special coding guidelines, e.g., via annotations. These restrictions still represent a high entry barrier for the wider community of programmers that new hybrid architectures are intended for. In this paper we revisit HW/SW partitioning and present a seamless programming flow for unrestricted, legacy C code. It consists of a retargetable GCC plugin that automatically identifies code sections for hardware acceleration and generates code accordingly. The proposed workflow was evaluated on the Xilinx Zynq platform using unmodified code from an embedded benchmark suite.

Abstract
In order to perform reliable computations on unreliable hardware, software-based protection mechanisms have been proposed. In this paper we present a compiler infrastructure for software-based code hardening based on encoding. We analyze the trade-off between performance and fault coverage. We look at different code generation strategies that improve the performance of hardened programs by up to 2x while incurring little fault coverage degradation.
