Hi everyone,

I'm trying to model a slab of Ge but I get the following errors:

I checked the OUTCAR and all the nearest neighbor lengths are quite reasonable. I also tried both ALGO = Normal and Fast with the same result. The strange thing is, I've done a few very similar slab calculations and everything went great with no errors, so I'm at a loss at what could make this calculation different.

As I suppose the TACC people have installed vasp properly, the reason for the ZPOTRF error must be related to your input, please check ALL distances (also those of the atoms with the neighbors in the periodically repeated cell!) once more

Hello, I have also recently noticed this problem while trying to run a TST style code but I get this error after the first itteration has already finished. I also get fewer repeats of this error when i reduce the MPI parallelization.
Here is my output:

| ADVICE TO THIS USER RUNNING 'VASP/VAMP' (HEAR YOUR MASTER'S VOICE ...): |
| |
| You have a (more or less) 'large supercell' and for larger cells |
| it might be more efficient to use real space projection opertators |
| So try LREAL= Auto in the INCAR file. |
| Mind: At the moment your POTCAR file does not contain real space |
| projectors, and has to be modified, BUT if you |
| want to do an extremely accurate calculation you might also keep the |
| reciprocal projection scheme (i.e. LREAL=.FALSE.) |

The run then freezes on this RMM step which is also strange.

Thanks,
