We describe a number of algorithms for the model for parallel computation called parallel alternating-direction access machine (PADAM). This model has the memory modules of the global memory arranged as a two-dimensional array, with each processor assigned to a row and a column, the processors can switch synchronously between row and column access modes. We study the issues of inter-processor communication and of e cient use of memory on the PADAM, and develop: an optimal routing scheme among
