Application Details

• Description: OSMesa is used since Octave 4.0 for offscreen rendering from OpenGL toolkits FLTK and Qt.
• Version: 2016-12-21 (compiled with gcc)
• Modules: sparsehash/2016-12-21/gcc-4.9.3
• Licence: Github, open-source

Usage

The sparsehash package consists of two hashtable implementations: sparse, which is designed to be very space efficient, and dense, which is designed to be very time efficient. For each one, the package provides both a hash-map and a hash-set, to mirror the classes in the common STL implementation.

These classes are:

• sparse_hash_map
• sparse_hash_set
• dense_hash_map
• dense_hash_set

In addition to the hash-map (and hash-set) classes, there's also a lower-level class that implements a "sparse" array. This class can be useful in its own right; consider using it when you'd normally use a sparse_hash_map, but your keys are all smallish integers.

Example

[username@login01 ~]$ module add  sparsehash/2016-12-21/gcc-4.9.3
