[Wien] strange time using -it switch

[Yongsheng Zhang]

I think I am using $SCRATCH. In my .cshrc file, I have the line,
setenv SCRATCH ./

This machine is a shared memory machine, 4 CPUs in one node. Since the
communication between nodes is slow, I only use one node in k-point
parallel style NOT MPI parallel.

The same thing happens on our IBM Linux cluster, 2 CPUs in one node. -it
switch only works with the line without "$para". It is not a shared
memory machine, and I use "ssh" for parallelization. Moreover, on this
machine, the "-it" switch meets another problem: The first full
diagonalization iteration is fine, and memory is enough for the
calculation, but when it switches to "-it" in the second iteration, and
copy case.vector into case.vector_old correctly, it says "insufficiently
virtual memory".

.....

Then I do a test, turning off the "-it" switch, and the job just run
smoothly.


Thank you very much
