Working on a grid of 40 nodes

Hello. I would like to run a monte carlo simulation for snr=2:0.5:5 and 1000 iterations for every snr on my university grid.It has 40 nodes and each node has 4 cores. I set 1 worker per node and i made 35 tasks like:

t1 = createTask(j, @mcc, 2, {2,1,200,10000});

t2 = createTask(j, @mcc, 2, {2,201,400,10000});

t3 = createTask(j, @mcc, 2, {2,401,600,10000});

t4 = createTask(j, @mcc, 2, {2,601,800,10000});

t5 = createTask(j, @mcc, 2, {2,801,1000,10000});

t6 = createTask(j, @mcc, 2, {2.5,1,200,10000});

....

t35 = createTask(j, @mcc, 2, {5,801,1000,10000});

where

 t = createTask(j, @mcc, 2, {snr,j_start,j_end,length of code});

Every node had 25% cpu usage.So i set 4 workers per node and i made 140 tasks like:

t1 = createTask(j, @mcc, 2, {2,1,50,10000});

t2 = createTask(j, @mcc, 2, {2,51,100,10000});

t3 = createTask(j, @mcc, 2, {2,101,150,10000});

t4 = createTask(j, @mcc, 2, {2,151,200,10000});

....

t140= createTask(j, @mcc, 2, {5,951,1000,10000});

Now, every node has 100%cpu usage.

My questions are:

1.)Is there any reason to use matlabpool somewhere in my program?

2.)Is there any better way to run my program?
