The following is the Hardware topology of the compute node I am using, a obtained
by using lstopo.

Machine (16GB)
Socket L#0
    L2 L#0 (6144KB)
      L1 L#0 (32KB) + Core L#0 + PU L#0 (P#0)
      L1 L#1 (32KB) + Core L#1 + PU L#1 (P#4)
    L2 L#1 (6144KB)
      L1 L#2 (32KB) + Core L#2 + PU L#2 (P#2)
      L1 L#3 (32KB) + Core L#3 + PU L#3 (P#6)
Socket L#1
    L2 L#2 (6144KB)
      L1 L#4 (32KB) + Core L#4 + PU L#4 (P#1)
      L1 L#5 (32KB) + Core L#5 + PU L#5 (P#5)
    L2 L#3 (6144KB)
      L1 L#6 (32KB) + Core L#6 + PU L#6 (P#3)
      L1 L#7 (32KB) + Core L#7 + PU L#7 (P#7)

It has 4 cores on each socket. But the cores like(0 and 4, 1 and 5 etc.) are to be considered on the same die?

Thanks
