General Questions and Answers / Re: ATKError: bad allocation
« on: April 25, 2009, 17:32 »
I have already posted my input files.
I think this problem may be caused by the lack of memory. Although the processor is quad-core one, I run only one atk process on it. There's more than 3.5G physical memory available for ATK and the peak memory it used is no more than 2.0G. I tried to reduce the k-point number in z-axis to 10, but there's the same error when the two probe calculation starts. Today I moved the calculation to a linux workstation, the memory is also 4G on it. By now the calculation is going on well without the same error even when the input file is the 100 k-ponit in z-axis.
