Soft error resilient QR factorization for hybrid system with GPGPU

► A soft error resilient QR algorithm for hybrid architecture with CPU and GPU was developed. ► Soft errors during QR factorization in the entire matrix can be detected and corrected. ► Performance impact to the baseline MAGMA QR implementation is low. ► Similar methods can be applied to other one-sided factorization like Cholesky and LU factorization.
