abstract = {This release features a number of changes in the parallel
implementation and the algorithm. The QR factorization,
which was previously done redundantly on each MPI process,
is not parallelized on a 1D sub-grid of the 2D MPI cartesian
grid. As a consequence of the additional parallelization,
the number and structure of the workspace buffers has
changed greatly diminishing the memory footprint of the
entire library The use of the postApplication function has
been substituted with the result that some of the
communication is now hidden behind computation during the
execution of the Rayleigh-Ritz kernel and the Residual
kernel The parallel HouseholderQR algorithm has been
substituted with the CholeskyQR algorithm (and its more
stable variants). A mechanism to avoid failure of this
algorithm has been introduced based on numerical analysis
results. A new parallel random generator has been added to
reduce the time spent initializing the computation,
especially for large scale problems.},
