MILC-based code for nHYP-smeared staggered fermions and more

Top-level directories follow the MILC layout
generic        -- Procedures common to most applications: communications, I/O, data layout, pure-gauge computations, etc.
generic_ks     -- Procedures common to staggered-fermion (Kogut--Susskind) applications
generic_nhyp   -- Procedures common to nHYP-smeared applications
generic_wilson -- Procedures common to Wilson-fermion applications
include        -- Header files for common procedures
libraries      -- Single processor linear algebra routines

Then there are various application directories, each with more detailed READMEs:
KS_nHYP_FA        -- nHYP-smeared staggered HMC with fundamental and adjoint plaquette terms in gauge action
S4b_params        -- Order parameters for S4-broken lattice phase
blocked_eig       -- Measure eigenvalues on RG-blocked lattice
check_load        -- Just load lattice to check plaquette and link trace
double_lattice    -- Save lattice doubled in all four directions with periodic boundary conditions
eig_KS_Kalkreuter -- Native staggered Dirac eigenvalue calculations using Kalkreuter algorithm
eig_KS_PRIMME     -- Good staggered Dirac eigenvalue calculations using PRIMME
eig_Wilson_PRIMME -- Good (hermitian) Wilson Dirac eigenvalue calculations using PRIMME
hvy_qpot          -- Wilson loops for heavy quark (static) potential
ks_spectrum       -- Staggered spectrum
ks_vacpol         -- Staggered vacuum polarization tensors for S parameter
mcrg_blocking     -- RG blocking and related measurements
mode_number       -- Stochastic staggered eigenvalue mode number nu(lambda)
smearing          -- HYP smear and save for analyses using different code bases
wilson_flow       -- Wilson flow with optional RG-blocking and measurements

Finally, the testsuite directory contains some sample input files and corresponding output for testing

Dependences:
The good eigenvalue measurements require PRIMME and LAPACK
