memory issues

Dear Dr. Ozaki,

I run a small job (10 atoms, 100 Ry cutoff, 12x12x12 k-point mesh) in parallel (10 cpus= 5 nodes with 4 Gb memory each). I noticed that for this job each openmx process asked about 30-40% of memory (~1.5Gb). On other cluster (sgi altix, shared memory), each process uses 10Gb memory. I am a little bit puzzled, because even plane wave calculations for this job use smaller amount of memory than openmx. Is it normal?

The required memory size seems to be larger than what I feel.
It is a good indication which tells us where memory is wasted.
I will try to fix the origin if you send me the input file.
