RE: [Condor-users] network file access between linux and windows

[RÃgis Baudu <Regis.Baudu@xxxxxxxxxxxxx>]

thanks a lot for your answers. I am going to test samba.
But, I am not sure to well understand the 2 following answers.
Is the first solution using samba requires specific setting between windows account and unix file/directory permissions/ownerships ?
 
In our case, the whole simulation files need to be access by the program. Does it mean that the Samba solution does not prevent data transfer on windows machine ? If yes, is there other solutions. If not, what do you mean by "Data Transfer would therefore not be avoided." ?
 
thanks a lot
RÃgis

	If the whole files need to be accessed in the runs, then by the time the job
	has completed, all the data in the simulation files will still have to have
	been transferred. Data Transfer would therefore not be avoided.
	
	The pros and cons to this (and other networked files solutions) compared to
	pre-staging the input files are:
	* Data transfer is done piecemeal during the run of the program, rather than
	  in one go before your program starts. Both methods have their own implications
	  on network performance.
	* The Windows machines never need to have the whole file on their machine at
	  one time.
