First parallel implementation of the CESTAC Method with self validation
First parallel implementation of the CESTAC Method with self validation
With the CESTAC method, which allows to validate numerical computation, one needs to run the code several times (in practice 3 times). The CADNA library (Control of Accuracy and Debugging for Numerical Applications) proposes a sequential and synchronous implementation of the CESTAC method. By using CADNA the computation time is multiplied by a factor which varies from 5 to 8 without the self validation of the method and by a factor around 15 with the self validation. These ratios are too important. This paper presents the first results obtained with a parallel implementation of the CESTAC method which includes the self validation.
