Using gd_sendtext in Matlab
Type gd_sendtext(‘00447880707831’, ‘job done, results send to [email protected]’) in Matlab environment as shown below
Check if the user has a valid proxy certificate Create a proxy if there is no valid one Submit a job to Globus Server Start the Messenger Application Send the message to the Messenger Server Receive the message from the mobile phone

Future Work
• Implement the other way communication• Send a replied message from mobile phone to
the messenger server• Update the entry in the database• Query the entry from the application in Matlab
