Dear all,

I am using nwchem-6.6. I got the following error. It says the available GA memory is 729192872 bytes and it is trying to create ga of size 957293768. Then I got the error. How can I solve this issue? (e.g. how can I enlarge available ga memory?) Thanks.

v2    file size   =         39892107
4-index algorithm nr. 13 is used
imaxsize = 40
imaxsize ichop = 0
