Dear all,

I would like to know how to get the required memory before calculation.

Some posts say about "makeparam" but it seems not available in vasp5.4.4, right?

I tried "make makeparam" in vasp.5.4.4 directory but

"make: *** No rule to make target `makeparam'. Stop." ---- this showed up.

Is there any other tool to get the required memory for the calculation ??

Thanks!

The use of makeparam has been long gone from the code and is not available in VASP 5.4.4 or higher.

Unfortunately there is no overall memory estimation in the code now. Upcoming releases will have a memory estimation for GW. We also plan to work on further extending the memory estimation to others parts in the code.
Unfortunately it is a cumbersome task to program that in, since almost every array is dynamically allocated at different places in the code depending on the calculational parameters.
