# GENERAL NOTES
|
||
|
|
#
|
||
|
|
# 1) Any line beginning with a "#" is considered a comment and will be
|
||
|
|
# ignored by the file parser.
|
||
|
|
#
|
||
|
|
# 2) The order of the lines IS NOT significant.
|
||
|
|
#
|
||
|
|
# 3) Any lines that are optional are marked as such in this file. Unless
|
||
|
|
# otherwise noted a line is required to exist in any input file.
|
||
|
|
#
|
||
|
|
# 4) The default file name expected by nem_spread is "nem_spread.inp". This
|
||
|
|
# can be overridden on the command line (see the nem_spread.man file for
|
||
|
|
# more on this).
|
||
|
|
#
|
||
|
|
# 5) The case of words IS NOT significant, e.g., "file" IS equivalent
|
||
|
|
# to "FILE" or "File", etc.
|
||
|
|
#
|
||
|
|
# 6) The amount of blank space in between words is also significant. Each
|
||
|
|
# word should only be separated by a single space.
|
||
|
|
#
|
||
|
|
# 7) Blank lines are ignored.

# although for most cases only a couple will be needed. The options are:
|

|
|
#
|
||
|
|
# number=<integer> - this is the number of parallel disks that the
|
||
|
|
# results files are spread over. This number must
|
||
|
|
# be specified, and must be first in the options
|
||
|
|
# list.
|
||
|
|
# list={list} - OPTIONAL, If the disks are not sequential, then a
|
||
|
|
# list of disk numbers can be given. This list should

|
|
# be enclosed in brackets "{}", and the disk numbers

|
# blank space, tab, or semicolon.

|

|
|
# disk numbers begin with. If no number is specified,
|
||
|
|
# this defaults to 1. This option is ignored if
|
||
|
|
# "list" is specified.
|
||
|
|
# zeros - OPTIONAL, This specifies that leading zeros are
|
||
|
|
# used in the parallel file naming convention. For
|
||
|
|
# example, on the Paragon, the file name for the
|
||
|
|
# first pfs disk is "/pfs/tmp/io_01/". If this is

# specified, then the default is not to have leading

|
|
# zeros in the path name, such as on the teraflop
|
||
|
|
# machine "/pfs/tmp_1/".

|
||
|
|
# is to stage the writes.

|
# name. For example, if one is running on an SGI workstation and

||
|
|
# using the "tflop" numbering scheme then you could use something
|

|
|
# similar to "/usr/tmp/pio_" in this field so that files would be
