+If you are having trouble building OpenBLAS out of the box, you may need to specify your CPU Architecture.
+Common architecture options include SandyBridge and Haswell. Even if your build worked correctly, it may
+not be optimal. The default architecture, if not specified, is Nehalem, which is probably not the ideal
+choice unless using an older computer.
+
+To specify the architecture simply use the TARGET flag. For example, TARGET=SANDYBRIDGE will build for
+the SandyBridge architecture. Similarly, TARGET=HASWELL will target the Haswell (or Crystalwell)
+architecture(s). To do this simply modify the BUILD_COMMAND to include this flag ____after____ the call
+to $(MAKE) as it must be an argument to make. It is recommend the same be done for the INSTALL_COMMAND
+as well.
+
+More information can be found on the OpenBLAS GitHub webpage ( https://github.com/xianyi/OpenBLAS/ ). A list
+of architectures supported can be found here ( https://github.com/xianyi/OpenBLAS/blob/develop/TargetList.txt ).
+Note that at the time of writing this READNME, the list has not been updated in about a year; so, it does not
+list HASWELL even though it is supported by the version we are using.
