Current hardware for compute intensive tasks includes a large amount of processing facilities which is sometimes hard to use in an optimized way. High performance computing (HPC) is always focused in solving grand challenge (or, at least, compute intensive) problems for which the response time is the priority. We have been working from two different but(More)
The challenge of improving the performance of current processors is achieved by increasing the integration scale. This carries a growing vulnerability to transient faults, which increase their impact on multicore clusters running large scientific parallel applications. The requirement for enhancing the reliability of these systems, coupled with the high(More)
