Exponentially increasing power densities in current day designs due to aggressive technology scaling has resulted in temperature being one of the primary design constraint along with others like timing, area and power. Lot of design techniques are being adopted during physical design stage to minimize the power, apart from the architectural techniques like throttling for dynamic thermal management. In this work we propose a practical methodology for better thermal management by floorplan modifications based on thermal hotspots obtained through dynamic simulations, without disturbing the logical connectivity information. This methodology definitely warrants the benefits which can be readily realized by doing this analysis early in the design cycle. This can also improve the placement of the thermal sensors and boost additional performance which can be extracted by their delayed triggering, considering the lateral spreading due to better floorplanning.

The unique architecture of the heterogeneous multi-core Cell processor offers great potential for high performance computing. It offers features such as high memory bandwidth using DMA, user managed local stores and SIMD architecture. In this paper, we present strategies for leveraging these features to develop a high performance BLAS library. We propose techniques to partition and distribute data across SPEs for handling DMA efficiently. We show that suitable pre-processing of data leads to significant performance improvements, particularly when data is unaligned. In addition, we use a combination of two kernels -a specialized high performance kernel for the more frequently occurring cases and a generic kernel for handling boundary cases -to obtain better performance. Using these techniques for double precision, we obtain up to 70-80% of peak performance for different memory bandwidth bound BLAS level 1 and 2 routines and up to 80-90% for computation bound BLAS level 3 routines.
