ga get2eri - cannot allocate buf error


  • Guest -
Dear All,

Sometimes I get the subj. error while running relativistic computations, as follows:
=====
convergence iter energy DeltaE RMS-Dens Diis-err time
---------------- ----- ----------------- --------- --------- ---------  ------
d= 0,ls=0.0,diis 1 -14268.4248148144 -1.51D+04 3.70D-02 1.17D+00 347.8
------------------------------------------------------------------------
ga_get2eri: cannot allocate buf 1
------------------------------------------------------------------------
------------------------------------------------------------------------
current input line :
182: task dft energy

==


Some of the isomeric molecules do compute energy, but some others fail. What could be the reason, and how to workaround it? Thank you!

You are simply running out of memory in your calculation. As this call uses local memory, you can specifically increase the stack memory without increasing global.
