Hello
when we have an instruction like, a[i] = a[i] +b [I]
do we need write allocation for a[i], since it is loaded before?

Hi Mohammad,
Write-Allocate (WA) was covered in slide set 5 by Prof. Wellein, please check again in the slides or your notes from the lecture.
Think about what WA (or "Read For Ownership"/RFO) means, when it is triggered and what's the difference to a "normal" Read operation.
Best,
Jan
