Differences in Approach or Implementation Status
Some of the libraries have seen more extensive development than the Omega Library in the early 2000s, and in many places has much more sophisticated algorithms. In particular, users have reported good results with the Cloog code generator (both in terms of the code generated, and in terms of ability to control trade-offs when generating code), and with the algorithms for counting integer solutions (Alexander Barvinok's work requires a vertex description of the polytope, which is not supported in the Omega Library).
There are several other points on which the frameworks differ, specifically:

Famous quotes containing the words differences, approach and/or status:
“The country is fed up with children and their problems. For the first time in history, the differences in outlook between people raising children and those who are not are beginning to assume some political significance. This difference is already a part of the conflicts in local school politics. It may spread to other levels of government. Society has less time for the concerns of those who raise the young or try to teach them.”
—Joseph Featherstone (20th century)
“There is no calm philosophy of life here, such as you might put at the end of the Almanac, to hang over the farmer’s hearth,—how men shall live in these winter, in these summer days. No philosophy, properly speaking, of love, or friendship, or religion, or politics, or education, or nature, or spirit; perhaps a nearer approach to a philosophy of kingship, and of the place of the literary man, than of anything else.”
—Henry David Thoreau (1817–1862)
“A genuine Left doesn’t consider anyone’s suffering irrelevant or titillating; nor does it function as a microcosm of capitalist economy, with men competing for power and status at the top, and women doing all the work at the bottom.... Goodbye to all that.”
—Robin Morgan (b. 1941)
