We analyze representatives in terms of many aspects including programming model, languages, supported platforms, license, optimization goals, ease of programming, debugging, deployment, portability, level of parallelism, constructs enabling parallelism and synchronization, features introduced in recent versions indicating trends, support for hybridity in parallel execution, and disadvantages. Such detailed analysis has led us to the identification of trends in high-performance computing and of the challenges to be addressed in the near future. It can help to shape future versions of programming standards, select technologies best matching programmers’ needs, and avoid potential difficulties while using high- performance computing systems. -

Don’t sit on the fence A static analysis approach to automatic fence insertion Jade Alglave1, Daniel Kroening2, Vincent Nimal2, and Daniel Poetzl2 1 University College London, UK 2University of Oxford, UK Abstract Modern architectures rely on memory fences to prevent undesired weakenings of memory consistency. As the fences’ semantics may be subtle, the automation of their placement is highly desirable. But precise methods for restoring consistency do not scale to deployed systems code. We choose to trade some precision for genuine scalability: our technique is suitable for large code bases. We implement it in our new musketeer tool, and detail experiments on more than 350 executables of packages found in Debian Linux 7.1, e.g. memcached (about 10000 LoC). 1 Introduction Concurrent programs are hard to design and implement, especially when running on multiprocessor archi- tectures. Multiprocessors implement weak memory models, which feature e.g. instruction reordering, store buffering (both appearing on x86), or store atomicity relaxation (a particularity of Power and ARM). Hence, multiprocessors allow more behaviours than Lamport’s Sequential Consistency (SC) [Lam79], a theoretical model where the execution of a program corresponds to an interleaving of the different threads. This has a dramatic effect on programmers, most of whom learned to program with SC. Fortunately, architectures provide special fence (or barrier) instructions to prevent certain behaviours. Yet both the questions of where and how to insert fences are contentious, as fences are architecture-specific and expensive. Attempts at automatically placing fences include Visual Studio 2013, which offers an option to guarantee acquire/release semantics (we study the performance impact of this policy in Sec.
