StarSs is a task-based programming model that allows to parallelize sequential applications by means of annotating the code with compiler directives. The model further supports transparent execution of designated tasks on heterogeneous platforms, inc

The appearance of multi/many-core processors created a gap between the parallel hardware and sequential software. Furthermore, this gap keeps increasing, since the community cannot find an appealing solution for parallelizing applications. We propose

The multicore era has increased the need for highly parallel software. Since automatic parallelization turned out ineffective for many production codes, the community hopes for the development of tools that may assist parallelization, providing hints

The years of practice in optimizing applications point that the major issue is focus - identifying the critical code section whose optimization would yield the highest overall speedup. While this issue is mainly solved for sequential applications, it

Task-based parallel programming languages require the programmer to partition the traditional sequential code into smaller tasks in order to take advantage of the existing dataflow parallelism inherent in the applications. However, obtaining the part

Overlapping communication and computation allows both processors and network to be utilized concurrently and leads to two clear benefits: overall speedup and a reduction in network performance requirements. Still, it remains unclear how much overlap
