Hi, everyone,<br><br>I'm trying to do DF-DFT-SAPT calculations. And I started with the sample example of Ne-Ar interactions.<br><br>The calculation was ran with 8 processors. <br>The job required 490GB memory. If the allocated memory is smaller than 400GB, the job would be killed due to inadequate memory.<br>
<br>The simulation time for the job is around one hour, which is much long than DFT-SAPT calculation of the same system (which only takes about 1 minute with 500MB memory).<br>The computation resources I'm using is a distributed-memory system. And I would like to provide more details of the clusters if necessary.<br>
<br>Despite the long simulation time, the simulation result is the same as the sample output.<br><br>The input and output file are attached.<br><br>Is there any keyword I should use to reduce the memory use and simulation time?<br>
If I'm speculating that the density fitting code is not compiled properly, anything I should do to verify that and how I can fix this compiling problem?<br><br>Any hint is appreciated. Do let me know if the question is not made clear.<br>
<br>Thank you.<br><br>Best,<br>Yanbin<br>
