BLACS -- Example Programs
HELLO is one of the simplest BLACS programs. This program takes the available processes, forms them into a process grid, and then has each process check in with the process at (0,0) in the process grid.
PI calculates the value of pi, using numerical integration with parallel processing, and clocks the solution time.
PROCMAP illustrates how to map processes to a grid using BLACS_GRIDMAP. This is a fundamental example using simultaneous multiple (possibly overlapping) grids.
