Thank you Sir, runsp_lapw -it gave me an error: foreach. So I am running with runsp_lapw .... script.
If I run it with Rkmax=6 then it does not show me any warning. At the FAQ of Wienk page standard RMT for O is 6.5 but it also gave me RKmax reduced warning. If someone advises me that I can take RKMAX=6 for O2 system then only I can proceed. I do not have any good facility.

If ~8 GB is your total RAM, keep in mind that the Linux operating might use around 1 GB. Using top [https://superuser.com/questions/282867/why-does-the-memory-usage-in-top-not-add-up ] or a system monitor [https://askubuntu.com/questions/29757/what-can-replace-system-monitoring-in-the-top-gnome-panel-in-unity ], you can check for any unnecessary processes and kill them to try to gain back more "free" memory. Though, while this might help a little with memory, it likely won't help with the speed issue. For speed, you likely need mpi or iterative diagonalization. Are using iterative diagonalization (runsp -it) as was mentioned before: http://zeus.theochem.tuwien.ac.at/pipermail/wien/2017-November/027303.html If none of that helps, it looks like your stuck with doing less accurate calculations using small RKmax values.

But my system is having ~8 GB RAM: 7.6 GiB Intel® Core™ i5-3570K CPU @ 3.40GHz × 4 Intel® Ivybridge Desktop Dear Lyudmila Dobysheva I increase NMATMAX upto45000 and NUME at 10000. At this value, it gave me lapw1 error while at NMATMAX (NUME)=35000(8000) it taking too much time and even after three hrs lapw1 is running. I want to keep consistent RKMAX with the literature. Otherwise, my job is to calculate the thermodynamic stability and for the same, I need the cohessive energy of O also. Can I use RKmax 6.0 for O2 and for others I am tacking 7. If not then what should I do to run this O2 system?
