• Fixed bug in tuning of clover inversion if source destination are the same: source must be preserved and restored since tuning destroys the input.

• clover::FloatNOrder now uses vectorized load/store for improved performance of all algorithms that use this (clover inversion sees a 1.5x speedup). Added missing support for clover norm field save/…

• Set clover norm to 0.1, as 0.2 leads to poorly conditioned clover matrix that results in signficant errors in cholesky decomposition leading to failure in twisted-clover test.

• Clover inversion now uses grid-wide reduction rather than atomics to compute trace log: this makes the result reproducible after tuning has completed. Trace-log computation and twist parameters are…

• Added new parameters QudaInvertParam::compute_clover and QudaInvertParam::return_clover which are used to instruct loadcloverQuda whether to compute the clover field or to download it, and also onc…

• Added new command-line parameters to unit tests for enabling QUDA-side computation of the clover field (and inverse) and for setting the clover coefficient. Updated dslash_test for this: if --compu…
