DMA host to FPGA array size

$

Currently, I am sending 3 clusters with 11 element each to the FPGA (PXi-7833R).  I thought perhaps, it will be more resource efficient if I were to send the data to the FPGA through a DMA instead.  Is that the case?  

 

When the data arrives at the FPGA, I use a for loop to read all 33 elements into an array, and use the array to build the original 3 clusters within the FPGA.  By doing that, I eliminate the 3 clusters of the FPGA front panel.  On the FPGA side, I dequeue the 33 elements from the DMA with a for loop, but LabVIEW is telling that that array is not a fixed size.  Is there a way around this?
