The paper describes a generic, open-source infrastructure called SearchBestie (or S'Bestie for short) that we propose as a platform for experimenting with search-based techniques and for applying them in the area of software testing. Further, motivated by a lack of work on search-based testing targeted at identifying concurrency-related problems, we instantiate S'Bestie for search-based testing of concurrent programs using the IBM's concurrency testing infrastructure called ConTest. We demonstrate on series of experiments the capabilities of S'Bestie and (despite we have just made our first experiments with S'Bestie) also the fact that using search-based testing in the context of testing concurrent programs can be useful.

Coarse-grained reconfigurable array architectures have drawn increasing attention due to their good performance and flexibility. In general, they show high performance for compute-intensive kernel code, but cannot handle controlintensive parts efficiently, thereby degrading the overall performance. In this paper, we present automatic mapping of control-intensive kernels onto coarse-grained reconfigurable array architecture by using kernel-level speculative execution. Experimental results show that our automatic mapping tool successfully handles control-intensive kernels for coarsegrained reconfigurable array architecture. In particular, it improves the performance of the H.264 deblocking filters for luma and chroma over 26 and 16 times respectively compared to conventional software implementation. Compared to the approach using predicated execution, the proposed approach achieves 2.27 times performance enhancement.
Thermal management is critical for clusters because of the increasing power consumption of modern processors, compact server architectures and growing server density in data centers. Thermal balancing mitigates hot sp...
