Name

ccdgs - gather-scatter operations on large blocks of data

Synopsis

ccdgs [parameter=value]

Description

This program was purely written to check how your I/O subsystem is handling transposing matrices in 2D or 3D. Examples of use would be to see how a series of snapshots, e.g. an APT cube (where A=Attribute, P=Particle, T=Time) transforms to a series of orbits, an ATP cube. Typical sizes: A=10 P=10^6, T=10^3.

Parameters

The following parameters are recognized in any order if the keyword is also given:
in=
Input filename (2d/3d block of data) [???]
out=
Output filename (2d/3d block of data) [???]
size=
Size in nx,ny[,nz] [10,10,1]
bs=
Block size per item [4]
mode=
Mode of copy [xy]
offset=
Offset (not used) [0]
