# PROC¶

Specifies processor decomposition.

## Required Cards:¶

- PROC <int int int>
- The number of processor to be employed in each direction x, y, z (structured grids only). The product of the integers must equal the number of processor employed.

## Examples¶

2x2x2 decomposition

```
PROC 2 2 2
```

Force decomposition in z direction only. E.g. 1x1x8 decomposition.

```
PROC 1 1 8
```
