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 in, 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)
“No sooner had I glanced at this letter, than I concluded it to be that of which I was in search. To be sure, it was, to all appearance, radically different from the one of which the Prefect had read us so minute a description.... But, then, the radicalness of these differences ... these things ... were strongly corroborative of suspicion.”
—Edgar Allan Poe (1809–1849)
“The modern world needs people with a complex identity who are intellectually autonomous and prepared to cope with uncertainty; who are able to tolerate ambiguity and not be driven by fear into a rigid, single-solution approach to problems, who are rational, foresightful and who look for facts; who can draw inferences and can control their behavior in the light of foreseen consequences, who are altruistic and enjoy doing for others, and who understand social forces and trends.”
—Robert Havighurst (20th century)

Policemen so cherish their status as keepers of the peace and protectors of the public that they have occasionally been known to beat to death those citizens or groups who question that status.”
—David Mamet (b. 1947)
