Recently, we have received several inquiries about "Out of memory error occurred.", "No space left on device error occurred" , and "File writing stopped." when using Gaussian.
This error may be caused by a problem in specifying the environment variable GAUSS_SCRDIR, which has exhausted the scratch directory capacity of Gaussian.
In particular, if the following specification, which was recommended in the initial usage guide for TSUBAME3 and TSUBAME4, is still in place, the possibility of this problem occurring is very high.
export GAUSS_SCRDIR=$TMPDIR
The GAUSS_SCRDIR setting is automatically set in the Gaussian module provided by TSUBAME4.0,
If you are using Gaussian, please check the execution script to see if this specification remains.
If the specification remains, delete it.
If the scratch directory space is exhausted even after deleting the above specification and using the default local scratch area, please specify a group disk for the scratch directory.
