Dear Rudolf,
Thank you very much for your reply.
I have a suspension of polymers coupled with fluid. (LJ+LB)
Here are the parameters:
box_l = 300*sigma (box is a cube)
number of polymers = 300
beads per polymer = 26
All the particles = 300*26 =7800
LJ cut = sigma*(2**(1/6))
l_skin = 8.3 *sigma (set it thid to have 31cells in each direction)
LB cells = 50
number of cells in each direction = 31
Timing for 100 productive run after setting the system and warming up:
1core 17.824 s
2core 16.22 s
4core 15.93 s
8core 17.83 s
If I want get one node with 128 cores on cluster and only use 4 of them, the cluster support will not be happy.
Best regards,
Ahmad reza
