Christopher Kelly	d161c2dc35	Improved formating of timing output in mixed-prec multishift ... In test of mixed-prec multishift, added comparison against full double precision multishift both for timing and to cross-check the results	2021-01-20 15:42:06 -05:00
Christopher Kelly	7a06826cf1	Added option to NerscIO to disable exit on failing plaquette check allowing for circumvention of factor of 2 error in CPS-generated G-parity config headers ... Adapted mixed-prec multi-shift test to new way to pass gauge BC directions and added cmdline option to perform the G-parity plaquette comparison with the corrected plaquette when loading config	2021-01-20 13:31:50 -05:00
Christopher Kelly	901ee77b84	Mixed precision multishift test can now be performed with/without G-parity using cmdline check and can load a pregenerated configuration	2021-01-20 11:45:44 -05:00
Christopher Kelly	1b84f59273	Added a mixed precision multishift algorithm for which the matrix multiplies are performed in single precision but the search directions are accumulated in double precision. ... A reliable update step is performed at a tunable frequency to correct the residual. A final mixed-prec single-shift solve is performed on each pole to perform cleanup if necessary. A test is provided to demonstrate the algorithm.	2021-01-06 12:24:44 -05:00
