Dear everyone,
please help me overcome this problem with stacksize. This appeared when running vasp.
"OMP abort: Unable to set worker thread stack size to 2098176 bytes
Try reducing KMP_STACKSIZE or increasing the shell stack limit. "
Please tell me detail as much as possible.
Note: I'm a user, not the Admin of the computer system.
Thank you very much.

KMP_STACKSIZE is an environment variable in Open MP, it gives the available stack size for each thread.
please try (one of) the following
a) set KMP_STACKSIZE explicitely
(setenv KMP_STACKSIZE=2m would e.g. set it to 2 Megabytes)
please ask your sys admin about the maximum available stack size and/or to increase the stack size maximum..
b) check the stack limit of your shell ("ulimit -s"); if it is limited, please set "ulimit -s unlimited" for your shell (in the .bashrc file for example)

Huhu, I though I did. But my "setenv", "limit", "ulimit" commands didn't work. I'm trying to contact with sys admin now.

I came across this same problem when I accessed my work computer through SSH. When I use VASP on it "interactively" it works just fine. Setting KMP_STACKSIZE or using ulimit didn't work for me either. However, when I ran VASP in a new screen (just write 'screen') everything worked fine again. Hope this helps somebody, although perhaps not really the correct solution.
