Sir we have set OMP_NUM_THREAD = 8 and it using all the 8 processors as can also been seen from CPU_MONITOR<br>

<br></div>
OMP_NUM_THREAD = 8 does NOT give any speed up !! Did you check your running time with values of OMP_NUM_THREAD =1,2,4<br>
and a k-parallelization !<div><div></div><div class="h5"><br>
