Hi Frédéric,
I do have some new on it :). I have made some changes to dmtcp trunk
to allow changing checkpoint directory on-the-fly by a dmtcp plugin.
Here are the steps to use it:
1. Checkout latest dmtcp trunk:
svn co https://dmtcp.svn.sourceforge.net/svnroot/dmtcp/trunk dmtcp-trunk
2. Extract the attached dmtcp plugin and put the directory "ckptDir"
inside test/plugin/.
3. Compile DMTCP.
4. Goto test/plugin/ckptDir, modify ckptDir.c, and do a make to create
ckptDir.so.
The works by reading the file specified in ckptDir.c to find out the
checkpoint-directory. You can change the file specified in ckptDir.c
to point to a different directory before checkpoint and the new ckpt
images will be written in that directory.
To use this plugin, you have to modify your command line as follows:
dmtcp_checkpoint --with-plugin /path/to/ckptDir.so ./a.out
Let me know if you have any questions.
