A. Features of GridPortal 2.1

The following are the features included in the new version of GridPortal 2.1,

1. Job submission through Gridway by explicitly selecting the cluster
    This option is for users who want to submit their jobs to a specific cluster of their choice

2. Job submission through Gridway without selecting cluster
    This is the preferred option. Gridway will automatically select the best cluster in which the job can be executed based on CPU load. The local job scheduler (such as Torque) will in turn select the best nodes within that particular cluster

3. Resubmission of job
   Allows the user to view the selected Job Id details and Resubmit the jobs with/without updating the relevent fields.

4. Job submission with support of Wall time
    This option is for the users who want to run their application/job for a long time.

5. Job submission through GT4
    This option is for users who want to submit jobs directly to Globus without using the scheduler. We don.t support Heterogeneous jobs here

6. Compiler Service
    Here user can compile their application source code in GARUDA grid environment.

7. Mobile job resubmission and job status
   User can re submit job and the status of job by sending sms from mobile.

8. Job monitoring: Job Status, View/Download Output files, Cancel Jobs
    This option is for already submitted jobs, either through Gridway or through Globus. Cancel option is available only for Gridway jobs

9. File Management
    Here users can stage files into GSRM server.GSRM is the data grid solution for the GARUDA grid.user can manage his files by file operations like renaming, copying,deleting and moving.
