# Specify `cmake --build . --parallel N` to set the number of parallel
compilation jobs.
# Default is derived from CPUs available.

+# By default, cmake will try and discover which GPU architecture to use by
looking at
+# the available GPUs on the machine that you're building on. If you want to
build for
+# a specific GPU architecture or are building on a machine without a GPU, then
+# specify the MXNET_CUDA_ARCH option like:
+#
+# $ cmake .. -DMXNET_CUDA_ARCH=7.0
+#
+# In the example above we're building for sm_70 which is the Volta
architecture.

free to improve it. It may be better than documenting it twice. WDYT?
