Question about NML

["Cheng-Chang Wu" <chengchangwu-at-yahoo.com>]

Hi,

I've read "Writing NML Configuration Files". After that I try to understand
sim.nml. There are something not cleared in the document.

Taking a buffer line as example,

#  name             type          host        size    neut (old)  buffer# MP
B simmot_cmd  RTLMEM localhost 4096     0       0        14   16   1014
TCP=5005 xdr

what does xdr mean?

And in a process line,
#  name buffer                type         host          ops    server
timeout master cnum
P  emc  emcCommand   LOCAL   localhost   RW          0         1.0         1
0

what does the master field mean?
