In this paper we present a new stable algorithm for the parallel QR-decomposition of " tall and skinny " matrices. The algorithm has been developed for the dense symmetric eigensolver ELPA, whereat the QR-decomposition of tall and skinny matrices represents an important substep. Our new approach is based on the fast but unstable CholeskyQR algorithm [1]. We(More)
We report results of compositional analyses of 16 new lunar meteorite stones for which names have been approved since our report of last year and speculate about pairing relationships on the basis of composition and preliminary petrographic data. Lunar meteorites are a valuable opportunity to expand our lunar sample library. We have conducted preliminary(More)
