Detailed Description

template<typename CELL_TYPE>
class LibGeoDecomp::StripingSimulator< CELL_TYPE >

This class aims at providing a very simple, but working parallel simulation facility.

It's not very modular, it's not fast, but it's simple and it actually works.

CoordBox<DIM> LibGeoDecomp::StripingSimulator< CELL_TYPE >::adaptDimensions ( const WeightVec & newPartitions ) [inline, private]

resets various sizes, heights etc.

according to newPartitions, returns the new bounding box of the stripes. It doesn't actually resize the stripes since different actions are required during load balancing and initialization.

unsigned LibGeoDecomp::StripingSimulator< CELL_TYPE >::ghostHeightLower [private]

we need to distinguish four types of rims:

the inner rim is sent to neighboring nodes (and lies whithin our own stripe)
the outer rim is received from them (and is appended beneath/above our stripe)
the lower rim is located at the lower edge of our stripe (where the absolute value of the y-coordinates are higher),
the upper rim conversely is at the upper edge (smaller coordinate values)

we assume the inner and outer rims to be of the same size. "rim" is the same as "ghost" and "ghost region".
