pdime

Todo

This command has not yet been ported to the new APBS syntax (see YAML- and JSON-format input files).

Specify the processor array to be used in a parallel focusing (mg-para) calculation. The syntax is:

pdime {npx npy npz}

where npx npy npz are the integer number of processors to be used in the x-, y- and z-directions of the system. The product npx × npy × npz should be less than or equal to the total number of processors with which APBS was invoked (usually via mpirun). If more processors are provided at invocation than actually used during the run, the extra processors are not used in the calculation. The processors are tiled across the domain in a Cartesian fashion with a specified amount of overlap (see ofrac) between each processor to ensure continuity of the solution. Each processor’s subdomain will contain the number of grid points specified by the dime keyword. For broad spatial support of the splines, every charge included in partition needs to be at least 1 grid space (chgm spl0), 2 grid spaces (chgm spl2), or 3 grid spaces (chgm spl4) away from the partition boundary.
