Table 1.

Time comparison of running the ASCE method with different numbers of elements for 100 000 timesteps. Each row gives the real time taken to compute 100 000 timesteps of cell movement for a sample system, the first row with eight CPU cores working in parallel, the second for a single CPU, and the third with an older generation GPU. Column 1 gives the times for a system consisting of one element in a single cell. Column 2 is for 10 elements of the same type in a single cell. Column 3 is for 100 elements of the same type evenly divided into 10 cells. Column 4 is for 1000 elements of the same type divided evenly into 100 cells. Column 5 is for 100 cells, each containing five elements of one type and five elements of another type. The first four columns indicate performance for the standard SCE method while the final column (*) indicates performance for ASCE with two element types.
