follow dev70_3, the SU(3) feature of the gauge does not seem to be the cause of the problem, after removing the use of all SU(3) features in PyQCU/cpp/cuda/qcu/include/define.h, "Difference: 1.9331150241763544e-06" changed to "Difference: 7.450580540990326e-09" (clover_term in /root/PyQCU/examples/pyqcu/conftest.clover.bistabcg-v20260505.log and /root/PyQCU/examples/pyqcu/conftest.clover.bistabcg-v20260506.log), but the problem of abnormal total number of solver iterations in dev70_3 did not change significantly, so why is that???
