Re: [Dmtcp-forum] Moving DMTCP checkpoint problem

[Kapil A. <ka...@cc...>]

Hi Alan,

Could you please checkout the latest source from svn:
 svn checkout svn://svn.code.sf.net/p/dmtcp/code/branches/1.2 dmtcp-1.2

The dmtcp_resart_script.sh now accepts a --ckptdir flag where you can
specify the new checkpoint directory. I believe in your case, you would
want to use the same directory for both --resartdir and --ckptdir flags to
point to the same directory.

Thanks,
Kapil
