<div dir="ltr"><div dir="ltr"><div><div>Dears;</div></div><div>I am calculating the DOS for a structure of graphene-water system on top of SiO2 hydrogen passivated substrate. I am enabling verbosity = high to see all details, the calculation go through each k-point, but experiencing some ScaLAPACK warnings (where I found in this forum that is can be ignored).</div>
<div><br></div><div>The problem is in the NSCF calculation, where for most systems I have it works with small 8x8x1 k-point mesh but with 16x16x1 it can't work (even specifying less processes per nodes)...it stops at certain k-point and that is all. So, kindly advice me what to do?</div>
