To run narxnet in HPC machine for larder data

I have another question about running narx with bigg data. I tried increase the hidden size, to get better model.

seems like 300 is some upper limit for the hidden units allowed- memory error. So for 1000 it clearly says no.

with the narxnet of :

net = narxnet(1:25,1:25,1000);

I get this error .e file

{Error using zeros
    Requested 1000x54373200 (405.1GB) array exceeds maximum array size preference
    (377.4GB). This might cause MATLAB to become unresponsive.
    
    Error in nnet.internal.configure.inputWeight (line 25)
    net.IW{i,j} = zeros(newSize);
    
    Error in nnet.internal.configure.input (line 42)
    net = nnet.internal.configure.inputWeight(net,j,i,x);
    
    Error in network/configure (line 244)
    net = nnet.internal.configure.input(net,i,X{i});
    
    Error in preparets (line 302)
    net = configure(net,'input',xx(i,:),i);
    }

with the size 600 i get - out of memeory error, How to fix it to able to use the NARX for big data:

net = narxnet(1:25,1:25,600);

we get the following

{Out of memory.
