Allocateing 128 element fifo:
fifo = Fifo('test_fifo', FifoType.HOST_WO)
fifo_size = 128
fifo.allocate(device, graph.get_option(GraphOption.RO_INPUT_TENSOR_DESCRIPTORS)[0], fifo_size)
data = np.empty(shape=(32, 32)).astype(np.float32)
for i in range(fifo_size):
print(i)
fifo.write_elem(data, None)
write_elem starts blocking on iteration 64.
Is there some hidden limit to fifo sizes?
