<DIV><FONT size=2>Dear WIEN users</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I got a segmentation fault during lapw1. My diagnostics
follows.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I run WIEN2k on a case of 32 atoms (an organic molecule), for
this time I set Gmax to 14, <BR>Gmin is calculated to 8,1632etc</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>after about 5-15 s of lapw1 <BR>the program stops and
<BR>LAPW1.error says no more than: "error in lapw1"<BR>and
<BR>STDOUT:<BR>forrtl: severe (174): SIGSEGV, segmentation fault

<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>This happens while calculation of 2 following lighter cases
works nice:<BR>These lighter cases are:<BR>1. The same structure, 32 atoms. I
set Gmax to 10 and choose core orbitals separation <BR>energy in lstart to -4
(instead of -6, recomennded) /average lapw1 execution time here is 12 min/<BR>2.
An analogous structure consisting of 22 atoms -all other conditions are <BR>as
they are in the error-producing case-/average lapw1 execution time here is 5
min/</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I have IntelP4 2,8 GHz, Goto libs, and 1Gb of Ram <BR>of which
about 200Mb is free during the calculations</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Please help:<BR>Can one see which part of a computer such
segmentation error concerns?<BR>Is that so that WIEN stops on an error for
heavier cases instead of just working more slow?<BR>Please send any other of
your comments on my story</FONT></DIV>
