As modern memory subsystems have become complex, performance tuning of application code targeting for their deeper memory hierarchy is critical to rewarding their potential performance. However, it has been depending on time-consuming and empirical ...

Understanding and identifying performance problems is difficult for parallel applications, but is an essential part of software development for parallel systems. In addition to the same problems that exist when analysing sequential programs, software ...

Investigation of the runtime behavior is one of the most important processes for performance tuning on a computer system. Profiling tools have been widely used to detect hot- spots in a program. In addition to them, tracing tools produce valuable ...

Concurrency errors, like data races and deadlocks, are difficult to find due to the large number of possible interleavings in a parallel program. Dynamic tools analyze a single observed execution of a program, and even with multiple executions they can ...

Writing parallel programs is hard, especially for inexperienced programmers. Parallel language features are still being added on a regular basis to most modern object-oriented languages and this trend is likely to continue. Being able to support ...

The Model-Driven Engineering (MDE) paradigm has been successfully embraced for manufacturing maintainable software in several domains while decreasing costs and efforts. One of its principal concepts is rule-based Model Transformation (MT) that enables ...

Performance tuning on a single CPU is still an essential base for massively parallelized applications in the upcoming exascale era to achieve its potential performance against their peak. In this paper, we investigate room for performance improvement ...

To achieve performance improvement by using multi-core processor, efficient utilization of thread-level parallelism is essential. However, conventional parallel processing cannot efficiently utilize potential parallelism within program code, since ...

Linear algebra provides the building blocks for a wide variety of scientific and engineering simulation codes. Users face a world of continuously developing new algorithms and high-performance implementations of these fundamental calculations. In this ...
