ccdgs - gather-scatter operations on large blocks of data
ccdgs
[parameter=value]
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.
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]
