Linear parallel decomposition of tissue. Example for the case of two nodes (each with 8 cores and 2 GPU devices, that is, a total of 16 CPU cores and 4 GPU devices). Each CPU core processes one task. Four tasks are assigned to each GPU device. For instance, at node 0, GPU 0 processes tasks T ₁, T ₃, T ₅, and T ₇, and GPU 1 the tasks T ₂, T ₄, T ₆, and T ₈.
