This is MILC Version 7 code Gradually version 6 code is being ported to it and new modules have been added. So far the following applications have been tested: clover_dynamical clover_invert clover_invert2 ext_src file_utilities gluon_prop heavy ks_eigen ks_hl_spectrum ks_imp_dyn ks_imp_rhmc ks_imp_invert_multi ks_imp_utilities pure_gauge pw_nr_meson schroed_cl_inv smooth_inst symanzik_sl32 wilson_static Build the code with GNU make. See the README file in this directory for general instructions. Here are highlights of the changes: For version 7.6.2 Revise metadata for FNAL correlator files in clover_invert2 Add QOP and QDP support for clover inversions. Add heavy-light-light baryon code from Heechang Na. Add ks_eigen code from version 6 and fix QDP support. Add ext_src for generating extended source from propagators Add some spectrum calculations to HISQ targets in ks_imp_rhmc Add HISQ fermion code from Doug and Alexei Add link and action coeffs to all fermion_force calls. Remove global accessor calls for these coeffs. Change normalization of point sink props in ks_hl_spectrum fix seg fault, and allow suppression of correlators in log file. Fix nrestart treatment in QOP inverter calls. For version 7.6.0 Adds pw_nr_meson. Does P-wave charmonium. Support for FNAL correlator format for ks_hl_spectrum. Support for double-precision NERSC archive lattices. clover_invert2 enlarges the capabilities of clover_invert. Support for changed QOPQDP Asqtad inverter conventions in qopqdp-0.10.1 with a backward compatibility option in Makefile. Partial preparation for HISQ: move calls for fat link creation out of all staggered dslash and congrad. Changes API for all ks_congrad and dslash calls - hence a new minor version number. Fix bugs in io_source_w_fm.c and in io_helpers_w.c. Add capability of reading a sink smearing function. For version 7.5.0 Precision selection for QOP and QDP Asqtad fermion force (single & multisource) Change to true residual stopping condition in single mass staggered and clover inverters. Prepare for supporting FNAL relative residual. Support for fixed mesh layouts (e.g. BG/L and QCDOC) Support a variety of FNAL Wilson sources and propagator formats. Support for USQCD/SciDAC gauge file format in some applications. Dcache I/O support (FNAL) Drop site structure temps from gaugefix args. Drop site structure args from restrict_fourier args New interface for clover inverters. Z2 random number support in f_meas Support qopqdp-0.7.7 and later for fermion force. EVENANDODD KS matrix inversion now does odd-site polish Support for QCDOC multi Asqtad force and multi Asqtad inverter A few more less-used version 6 apps upgraded to version 7. For version 7.4.0 Mixed precision for QOP and QDP inverters, dslash, and supporting fermion links. Introduced precision selection "prec_pbp" for f_meas.c inversions. Made multicg option choice available to applications other than RHMC. Support qopqdp-0.7.7 including FNMAT version of multi fermion force "initialize_machine" now takes pointers to argc and **argv. Support USQCD metadata in SciDAC file output Print list of selected options during setup. Segregate inclusion of SciDAC headers for faster compilation times Libraries "make" builds both precisions independently. Make reporting of remapping time optional with macro REMAP. For version 7.3.1 Polished the parameter input format for the RHMC. Now allow comment lines beginning with # in parameter input. Added NERSC checksum to link trace. Added more precise timing to the QOP and QDP modules including remapping times. For version 7.3.0 Nearly complete QOP and QDP support for all major components of Asqtad molecular dynamics, including Doug's new multi fermion force. Reworked RHMC parameter input and Remez parameter output. Added support for more than two pseudofermion fields in RHMC Support different CG residuals for RHMC MD, FA, GR. Changed inline global make macros to C_GLOBAL_INLINE and SSE_GLOBAL_INLINE. Added file pointer to get_i, get_f, etc. Added nrestart to KS CG routines throughout. (These last changes affect most application subdirectories.) For version 7.2.2 Upgrade RHMC code to do concurrent EOS calculations Fix p4 capability in ks_imp_dyn. Distinguish inverter residuals for mol dyn and action. For version 7.2.1 Start supporting the QOP/QDP package Split out fermion_links_fn from quark_stuff but no QOP support for fat and long link generation, yet. Make sample files precision-specific For version 7.2.0.1 Correct the weights for QOP_asqtad_force_multi in fermion_force_asqtad_qop.c Restore clobbered sse directory. For version 7.2.0 Port clover_dynamical to Version 7 Add RHMC code and rearrange multicg and multi fermion force procedures Add Level 3 wrappers for Level 3 multicg and multi fermion force Begin adding plaquette and link trace to MILC file metadata. Add Urs's gluon_prop For version 7.1.12 Fix Level 3 fermion force coef usage Support new level 3 interface for asqtad_invert and asqtad_force Add clover_invert to Version 7. For version 7.1.11 Support new Level 3 API for Asqtad fermion force and inverter Support for QOP/QDP awaits upgrade. Change write_ksprop_info_item to use fwrite instead of fprintf Add MILC imitations of Level 3 force and inverter for testing Make dummy QCDML be legitimate XML For previous versions 7 1.
