The increase in the number of processor cores has opened up new opportunities to take advantage of the parallelism available in modern data-centric applications and workloads. On the other hand, parallelizing programs is still an error-prone and challenging task for the typical programmer. MPP 2016 brings together researchers and practitioners interested in developing novel computational models for parallel programming and architectures. Given the growing interest in task parallelism programming and execution models, MPP 2016 dedicated this edition to such programming model. Nevertheless, authors are also encouraged to submit original works. MPP 2016 will be held in conjunction with the 28th International Symposium on Computer Architecture and High Performance Computing (SBAC-PAD 2016), at Marina del Rey Marriott, Los Angeles, USA.
