branch is fairly wide ranging, and came from optimization of the Cineca staggered RHMC benchmark:\r\n* More robust SVD in HISQ\r\n* Unitarity checks now include a check for Nan\r\n* Improved performance of multi-shift solver\r\n  * Delay shift updates until middle of subsequent dslash to improve strong scaling\r\n  * Stop iterating on shifted systems if iterated residuals fall below precision limit\r\n* Optimization of HISQ and gauge force kernels through kernel fusion\r\n* Significant of gauge force routines\r\n* Reduced compilation time using trait mappers \r\n* Added `momActionQuda` for computing the momentum contribution to the action\r\n* Added `projectSU3Quda` for projecting the gauge field onto the SU(3) manifold (uses the projection from APE smearing)\r\n* Fixed bugs in gauge phase application kernel and added support for imaginary chemical potential (closes #284)\r\n* In the milc interface staggered solver, use the resident gauge field until it is invalidated by constructing a new set of fat/long links\r\n* Experimental support for fully GPU resident momentum: download when momActionQuda is computed and invalidate (disabled by default since this is not supported in mainline MILC)\r\n* LDG loads are now enabled by default when `gauge::FloatNOrder` is used\r\n* Improved debugging: added L1 norm reduction kernel and check for Nan when copying gauge fields (when debugging is enabled)\r\n* Minor bug fixes\r\n* Removal of dead code"},"comment":{"url":"https://api.github.com/repos/lattice/quda/issues/comments/145570127","html_url":"https://github.com/lattice/quda/pull/366#issuecomment-145570127","issue_url":"https://api.github.com/repos/lattice/quda/issues/366","id":145570127,"user":{"login":"mikeaclark","id":316771,"avatar_url":"https://avatars.githubusercontent.com/u/316771?v=3","gravatar_id":"","url":"https://api.github.com/users/mikeaclark","html_url":"https://github.com/mikeaclark","followers_url":"https://api.github.com/users/mikeaclark/followers","following_url":"https://api.github.com/users/mikeaclark/following{/other_user}","gists_url":"https://api.github.com/users/mikeaclark/gists{/gist_id}","starred_url":"https://api.github.com/users/mikeaclark/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mikeaclark/subscriptions","organizations_url":"https://api.github.com/users/mikeaclark/orgs","repos_url":"https://api.github.com/users/mikeaclark/repos","events_url":"https://api.github.com/users/mikeaclark/events{/privacy}","received_events_url":"https://api.github.com/users/mikeaclark/received_events","type":"User","site_admin":false},"created_at":"2015-10-05T15:28:32Z","updated_at":"2015-10-05T15:28:32Z","body":"Can
