Fortran and mkl also are the same?

I imply here that you have done the same for all three computers and 
obtained the same answers (?)

In some configurations, as far as I remember, the system does not 
transfer set-up to executing scripts. I'd advice you to add the command 
"ulimit -a" to run_lapw (or runsp_lapw if you have used this) and to 
check the output for each computer, no necessity to really make the 
cycle, it is sufficient to add this command somewhere in the beginning 
around lapw0 execution and a stop command just after it, and to see the

This (b) computer completes two iterations. Compare scf file with the 
scf file from (c) computer. Are these two iterations identical?

During these two iterations make "top" in terminal and check what 
happened with memory during lapw2. And maybe you see something during 
lapw2 in the third iteration.	

For the present, nothing more clever comes into my mind.
