GPU and Neural Network ... is this operation legitimate?

Hi, I need to compute many simple Neural Networks... thousands.
I would like to use a parallel for on the GPU.
The FIRST problem is that I am not able to compute the net on the GPU:
% Net creation
hiddenLayerSize = 10;
net = fitnet(hiddenLayerSize);
% Setup Division of Data for Training, Validation, Testing
net.divideParam.trainRatio = 70/100;
net.divideParam.valRatio = 15/100;
net.divideParam.testRatio = 15/100;
%Training
net.trainFcn = 'trainscg';
net.trainParam.showWindow = false;
net.trainParam.showCommandLine = false;
% Send input and target on the GPU
input_A=gpuArray(input)
target_A=gpuArray(target)
% Train
[net_new,~] = train(net,input_A,target_A)
I receive this error:
Error using network/train (line 293)
Number of samples (rows of gpuArrays) of data arguments do not match.
QUESTION:
Is it possibile to compute the net on the GPU (I want that every core train a different net)? If yes, what am I doing wrong?
