CodePeer 3.0 also adds many new features, including support for precise IEEE 754 floating-point semantics, added flexibility in analyzing complex projects, improved support for legacy Ada compilers, more precise diagnostic messages, and a new check on parameter aliasing.
It can be noticed that the off-norms do not reach the convergence criteria, and each size of the EVD array has different stop criteria for each rotation method (default IEEE 754 single).
It is IEEE 754 compliant, that is, it considers all exceptional cases.
The second part of testing was to compare the numerical stability of our algorithm, because IEEE 754 floating-point operations are not associative (Monniaux, 2008).
The new Tesla product family includes the Tesla S1070 1U computing system and the Tesla C1060 computing processor and delivers:Co Double the performance: up to 4 Teraflops per 1U systemCo Double precision: IEEE 754 arithmetic support Co Double the memory: with 16 Gigabytes of memory per 1U systemCo Up to 3x the power efficiency: for a more efficient computing environment
That is, some components of the IEEE 754 standard may not be followed in a particular computing environment because of the processor or compiler (or both) in use.
