void cps::compare_array_relative (  Float *  pion_corr_A, Float *  pion_corr_B, Float  tol, int  time_size )

Comparison of two arrays. Computes the relative difference between each number in the first array and the corresponding number in the second array. The differences are printed to stdout. If all differences are less than a specified tolerance, "test_result = PASS" is printed to stdout; otherwise "test_result = FAIL" is printed. Parameters: pion_corr_A  An floating-point array pion_corr_B  Another floating-point array tol  The tolerance time_size  The length of the arrays Definition at line 48 of file testing_framework_cmp.C. References cps::MPISCU::printf().

void cps::compare_float_relative (  Float  pion_corr_A, Float  pion_corr_B, Float  tol )

Comparison of two floating-point numbers. Computes the relative difference between two numbers The difference is printed to stdout. If the difference is less than a specified tolerance, "test_result = PASS" is printed to stdout; otherwise "test_result = FAIL" is printed. Parameters: pion_corr_A  An floating-point array pion_corr_B  Another floating-point array tol  The tolerance Definition at line 102 of file testing_framework_cmp.C. References cps::MPISCU::printf().

void cps::staggered_local_pion (  Lattice &  lat, Float  mass, IFloat *  pion_corr, int  time_size )

Simple pseudoscalar correlator. The correlation function is computed using a point source at the origin. Parameters: lat  The lattice object containing the gauge configuration. It is assumed that there are no spin degrees of freedom, so this should be a class derived from FstagTypes. mass  Valence quark mass parameter pion_corr  The timesliced pseudoscalar correlation funtion The  number of timeslices over which to compute the correlator. Postcondition: The correlator is written to the array and also printed to stdout. Definition at line 44 of file staggered_local_pion.C.
