Is the glass half empty or half full? shown that a speaker's choice of frame can reflect their knowledge of the environment, and that listeners can be sensitive to this information. Is the glass half empty or half full? "Is the glass half empty or half full?" is a common expression, a proverbial phrase, generally used rhetorically to indicate that a particular situation could be a cause for optimism (half full) or pessimism (half empty), or as a general litmus test to simply determine an individual's worldview. The purpose of the question is to demonstrate that the situation may be seen in different ways depending on one's point
GCD test arrays present in two or more statements, it can be calculated whether it is legal to parallelize the loop or not. A linear Diophantine equation has an integer solution x1, x2..., xn iff GCD (a1,a2.., an) divides c. E.g. GCD(2,-2) =2, 2 cannot divide 1. So, there is no integer solution for the equation above. It is difficult to analyze array references in compile time to determine data dependency (whether they point to same address or not). A simple and sufficient test for the absence of a dependence is the greatest common divisor (GCD) test. It is based on the
