Task Table

A TaskTable records tasks information.

• The entire task table belongs to the same BSPJobID.
• A 2d array space is allocated with numBSPTasks row, and maxTaskAttempts is configured to check if `attempt task' exceeds the upper bound.

• Each row's first slot (ie Task\[0\]) is assigned with a task where

TaskID's id: 1...N where N < numBSPTasks
TaskAttemptID' id: 1

• A task managed by the task table has attributes such that

{TaskID's id: 1...N where N < numBSPTasks, and the same row's id should equal.}
{TaskAttemptID's id: 1...M where M < maxTaskAttempts }
