CCL:G: Disk space error in DoCrtU when optimizing geometry in Gaussian

I think you can specify multiple scratch directories byt having multiple
 RWF files. Try adding something similar to your input file
 %rwf=/scratch-dir/file1.rwf, 1900MB, /scratch-dir/file2.rwf, 1900MB,
 In this example, 1900MB * 3 = 5,700 MB of scratch space is used.
 Not sure what SLURM is, but as long as you have read/write permission in a
 directory you can use as scratch, this should work. Else, contact your
 local IT Gods.
