In this work, a parallel adaptive algorithm for the computa- tion of a multidimensional integral on heterogeneous GPU and multicore based systems is described. Two dierent strategies have been combined together in the algorithm: a rst procedure is responsible for the load balancing among the threads on the multicore CPU and a second one is responsible for an ecient execution on the GPU of the computa- tional kernel. The performance is analyzed and experimental results on a system with a quad-core CPUs and two GPUs have been achieved.
