The ability to perform under pressure is necessary to achieve goals in various domains of life. We conducted a systematic review to synthesise findings from applied studies that focus on interventions developed to enhance an individual's ability to cope under performance pressure. Following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines, a comprehensi...

The eNANOS is an execution framework developed in the Barcelona Supercomputing Center. One of its main objectives is to provide a framework to execute multilevel parallel applications with low-level support. It is also able to provide information about the execution behavior of applications in run time. This information can be used by a Grid Resource Broker or metascheduler to improve its sched...

In single-objective optimization it is possible to find a global optimum, while in the multi-objective case no optimal solution is clearly defined, but several that simultaneously optimize all the objectives. However, the majority of this kind of problems cannot be solved exactly as they have very large and highly complex search spaces. Recently, meta-heuristic approaches have become important ...
