Several large randomized trials showed that tamoxifen alone is no more the standard adjuvant hormonal therapy for menopausal patients. Aromatase inhibitors, given upfront or sequentially after tamoxifen, confirmed their efficacy by improving disease free survival, risk of distant metastasis and overall survival in some situations or subgroups of patients. These drugs are usually well tolerated, but they clearly increase bone mineral density loss as well as the risk of fractures and their long term safety on the cardio-vascular system needs to be followed. Thus, even if the role of the aromatase inhibitors is now evident in the adjuvant therapy of postmenopausal women the benefice/risk ratio should be carefully evaluated for each patient.

This study looks at how increased memory utilisation affects throughput and energy consumption in scientific computing, especially in high-energy physics. Our aim is to minimise energy consumed by a set of jobs without increasing the processing time. The earlier tests indicated that, especially in data analysis, throughput can increase over 100% and energy consumption decrease 50% by processing multiple jobs in parallel per CPU core. Since jobs are heterogeneous, it is not possible to find an optimum value for the number of parallel jobs. A better solution is based on memory utilisation, but finding an optimum memory threshold is not straightforward. Therefore, a fuzzy logic-based algorithm was developed that can dynamically adapt the memory threshold based on the overall load. In this way, it is possible to keep memory consumption stable with different workloads while achieving significantly higher throughput and energy-efficiency than using a traditional fixed number of jobs or fixed memory threshold approaches.
