CCL:G: CIS calculations




The problem is probably indicated by the following line:

 LnScr1= 10419141632 LExtra=           0 Total=  48910147664

This "Total" is the disk space used in units of words (bytes / 8) and represents a value of about 364GB. Since you did not set a MaxDisk value (as indicated by MaxDisk=-1 in the output), G03/G09 is trying to write a scratch file of about 350GB. The "Erroneous write" line indicates a failed write, probably because you are out of space on the disk. Assuming CIS calculations in G03/G09 honor MaxDisk, set this value in your route line to the amount of scratch space you want the calculation to be able to use. Gaussian will choose a calculation routine (indicated by ITran=X where X is a number between 1 and 5) to try to remain within the MaxDisk limitation you specify.

Good luck,
Stephen

Dear Peter
I am not sure about your error, but could you change the name of your chk point file, I think you are running two jobs with the same check file name.
Have a go, if it didn't work, could you send your input and output files as attachment files?

Hello,

I'm trying to run CIS calculations. I'm getting the same mistake every time:

How can I overcome this problem?

I appreciate any help
