user don't get into trouble about this. You want to tune this
size to increse the number of processes. This is the
<tt>STACK_SIZE</tt> define in
- <tt>src/xbt/xbt_ucontext.c</tt>, which is 128kb by default.
+ <tt>src/xbt/xbt_context_sysv.c</tt>, which is 128kb by default.
Reduce this as much as you can, but be warned that if this value
is too low, you'll get a segfault. The token ring example, which
is quite simple, runs with 40kb stacks.
\subsubsection faq_trouble_errors_big_fat_warning I'm told that my XML files are too old.
-We have decided to change the units in SimGrid. Now we use Bytes, Flops and

+The format of the XML platform description files is sometimes
+improved. For example, we decided to change the units used in SimGrid
+from MBytes, MFlops and seconds to Bytes, Flops and seconds to ease
+people exchanging small messages. We also reworked the route
+descriptions to allow more compact descriptions.
+
+That is why the XML files are versionned using the 'version' attribute
+of the root tag. Currently, it should read:
\verbatim
- <platform_description version="1">
+ <platform version="2">
\endverbatim
-You should try to use the surfxml_update.pl script that can be found
-<a href="https://gforge.inria.fr/plugins/scmsvn/viewcvs.php/contrib/trunk/platform_generation/?rev=4721&root=simgrid"">here</a>.

+If your files are too old, you can use the simgrid_update_xml.pl
+script which can be found in the tools directory of the archive.
