[Wien] did parallel calculation take effect?

[Laurence Marks]

While we can partially help you with this, you do need to do some
thinking yourself. Some key questions:
a) Which are the "right" libraries to use? Since you appear to have
multiple copies, you need to verify what each of them are otherwise
you might be compiling with one and running with another.
b) Is LD_LIBRARY_PATH set correctly on the compute nodes? For
instance, do an ssh (or rsh) to one of them and then "echo
$LD_LIBRARY_PATH".
c) Are the shared library dependencies setup correctly? Do "man ldd",
"ldd lapw1" on your head node and also on the compute nodes. You may
want to look at "man ldconfig" as well.
d) Is LD_LIBRARY_PATH being exported in jobs? This is a slightly more
subtle issue, and you may simply want to run a job that does "echo
$LD_LIBRARY_PATH" and see the results.
e) Do you want to compile with static intel libraries or dynamic? Do
"man ifort" and/or "ifort -help link". If you don't understand the
difference between the two do a google search on "static linking" and
start reading.
