=head1 DESCRIPTION
|
||
|
|
|
||
|
|
simgrid_update_xml updates the simgrid XML file passed as argument. The file
|
||
|
|
is modified in place, without any kind of backup. You may want to save a copy
|
||
|
|
before running the script.
|
||
|
|
|
||
|
|
In SimGrid XML files, the standard version is indicated in the version
|
||
|
|
attribute of the platform tag. Current version is 4. Here is a list of major
|
||
|
|
changes in each version.

from MFlop/s to Flop/s
