Hi everybody,
To check the effect of %MEM on G94 jobs, i did 4 CCSD(T) freq
calculations using same input file but different %MEM=32, 64, 128 and
150MB. No other application prog. was running during these four jobs.

The result is:
  %MEM      CPU       RWF(MB)       MaxMem (from output)
   32mb    55m 35.2s   45           4194304   
   64mb    57m 11.8s   77           8388608
  128mb    59m 37.5s  141           16777216
  150mb   1h 0m 25.5s  163          19660800

It looks odd. Expert's comment please. 
Tapas
PS: I am using RS/6000 Model 590 and AIX4.2
    Total 256mb memory and 13(2+2+9)gb hard disk.
