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:
“Generally there is no consistent evidence of significant differences in school achievement between children of working and nonworking mothers, but differences that do appear are often related to maternal satisfaction with her chosen role, and the quality of substitute care.”
—Ruth E. Zambrana, U.S. researcher, M. Hurst, and R.L. Hite. “The Working Mother in Contemporary Perspectives: A Review of Literature,” Pediatrics (December 1979)
“When was it that the particles became
The whole man, that tempers and beliefs became
Temper and belief and that differences lost
Difference and were one? It had to be
In the presence of a solitude of the self....”
—Wallace Stevens (1879–1955)
“The nearer people approach old age the closer they return to a semblance of childhood, until the time comes for them to depart this life, again like children, neither tired of living nor aware of death.”
—Desiderius Erasmus (c. 1466–1536)
“What is clear is that Christianity directed increased attention to childhood. For the first time in history it seemed important to decide what the moral status of children was. In the midst of this sometimes excessive concern, a new sympathy for children was promoted. Sometimes this meant criticizing adults. . . . So far as parents were put on the defensive in this way, the beginning of the Christian era marks a revolution in the child’s status.”
—C. John Sommerville (20th century)
