Issue while running NWCHEM on more number of processors
Hi, Hubb,

Yes that was cluster issues and that is being solved.Thanks.

Now I am getting the following error when I try to run my input file on 128 processors. The same input file ran successfully on 64 processors.

Input file:



start 26dnt
