<div><font size="3">Dear CP2K developers and users,</font></div><div><font size="3"><br></font></div><div><font size="3">Recently we have attempted the GW calculations implemented in CP2K. Two warnings appeared. We have tried to eliminate these warnings for several days. However, the warnings can not be eliminated. The warnings are as follows:</font></div><div><br></div><div><i><font size="2">*** WARNING in rpa_main.F:314 :: Please use NUM_INTEG_POINTS 30 for ***<br> *** low-scaling GW to achieve good accuracy. ***<br><br><br> *** WARNING in rpa_main.F:320 :: The required number of quadrature point ***<br> *** exceeds the maximum possible in the Minimax quadrature scheme. The ***<br> *** number of quadrature point has been reset to 30. ***<br><br> MEMORY_INFO| Memory for MO-contracted integral tensor (compress 63.49 MiB<br> MEMORY_INFO| Compression factor: 3.75<br><br> *** WARNING in mp2_grids.F:152 :: You requested a large minimax grid (> ***<br> *** 20 points) for a small minimax range R (R < 100). That may lead to ***<br> *** numerical instabilities when computing minimax grid weights. You can ***<br> *** prevent small ranges by choosing a larger basis set with higher ***<br> *** angular momenta or alternatively using all-electron calculations. ***</font></i></div><div><i><font size="2"><br></font></i></div><div><i><font size="2"><br></font></i></div><div><font size="3">My questions are: <br></font></div><div><font size="3">1) Are these warnings important to the final results?</font></div><div><font size="3">2) If these warnings are important, how to eliminate them?</font></div>
