The Ram, in astronomy, a zodiacal and autumnal constellation (see illustration). Among the 12 zodiacal constellations, Aries was considered as the first, because about 2000 years ago when the zodiacal constellations were organized, the Sun was in Aries where it crossed the equator at vernal equinox. Today, because of the precession of the equinoxes, this reference point has moved into the constellation Pisces. However, Aries remains the first sign of the zodiac. See also Constellation.

Translation software from HP that runs on Itanium computers. It allows PA-RISC applications originally written for HP 9000 computers to run natively on Itanium computers running HP's Unix (HP-UX) operating system. Aries provides a way to run legacy applications "as is" before they can be recompiled into native Itanium programs.
Aries interprets PA-RISC instructions one at a time until it finds a code block that is executed a certain number of times. It then converts that code block into native IA-64 instructions and executes the native block the next time it is required. When the program is closed, the IA-64 code is discarded. See Itanium.
