 # rocm_bandwidth_test
+
+Introduction:
+#############
+
+RocBandwidthTest is designed to capture the performance characteristics of buffer
+copying and kernel read/write operations. The help screen of the benchmark
+shows various options one can use in initiating cop/read/writer operations.
+In addition one can also query the topology of the system in terms of memory
+pools and their agents
+
+Build Environment:
+##################
+
+To be able to build RocBandwidthTest, users must ensure that the build platform has
+following conditions satisfied:
+Build Procedure:
+################
+
+The following simply lists the steps to build RocBandwidthTest
+
+--- Define following environment variable to specify location of header
+    and library files
+
+    // Contains header files exported by ROC Runtime
+    ROCR_INC_DIR="Path of ROC Runtime Header Files"
+
+    // Contains library files exported by ROC Runtime
+    ROCR_LIB_DIR="Path of ROC Runtime Library Files"
+
+    // Contains header files exported by ROC Thunk
+    ROCT_INC_DIR="Path of ROC Runtime Header Files"
+
+    // Contains library files exported by ROC Thunk
+    ROCT_LIB_DIR="Path of ROC Runtime Library Files"
+
+--- Create a build directory in the project folder - roc_bandwidth_test.
+
+        e.g. mkdir ./build
+
+--- Set working directory to be the new build directory
+
+        e.g. cd ./build
+
+--- Invoke Cmake to interpret build rules and generate native build files
+    The argument for cmake should be the root folder of RocBandwidthTest
+    test suite
+
+        // Builds Release version (default)
+        // Assumes pwd is .../roc_bandwidth_test/build
+        e.g. cmake ..
+
+        // Builds Debug version
+        // Assumes pwd is .../roc_bandwidth_test/build
+        e.g. cmake -DCMAKE_BUILD_TYPE:STRING=Debug ..
+
+--- Invoke the native build rules generated by cmake to build the various
+    object, library and executable files
+
+        e.g. make
+
+--- Invoke the install command to copy build artifacts to pre-defined folders
+    of RocBandwidthTest suite. Upon completion artifacts will be copied to the
+    bin and lib directories of build directory
+
+        e.g. make install
+
+    @note: All executables will be found in <build_directory>/bin folder
