Observations<br />

1. There can be a provision for the user to list the various grid nodes participating in the<br />

computation with status like busy, idle etc.<br />

2. The total number of tasks and current task number are to be given to the subtasks by vishwa to<br />

allow writing parallel code. Splitting the data manually is tedious and time consuming. Once these two<br />

parameters are available, the sub task can read a selected region of the input data for processing.<br />

3. It is observed that, when given number of splits more than one, most of the time the sub tasks are<br />

executed on the same grid node and when executed on different nodes, the result is not properly<br />

combined.<br />

4. Finding the time requirement for the computation including task distribution and result<br />

aggregation is difficult.<br />

5. A provision can be given for submitting multiple source files including cpp files.<br />

6. The 'user' program could read the parameters (metafile, sub task file, result file etc) from a file to<br />

avoid entering these parameters every time for different runs.<br />

7. Displaying the entire result file onto the screen can be avoided.<br />
