-    To distribute the XeGPU operation to work items, the tensor_desc must be specified with the sg_map
-    attribute at the tensor description creation time.
-    Within the `sg_map`, `wi_layout` specifies the layout of work items,
-    describing the mapping of work items to the tensor.
-    wi_layout[0] x wi_layout[1] must be equal to the total number of work items within a subgroup.
-    `wi_data` specifies the minimum number of data elements assigned to each work item for a single distribution.
-
-    E.g., #xegpu.sg_map<wi_layout = [1, 16], wi_data = [1, 1]>
-    In this example, the subgroup has 16 work items in wi_layout=[1, 16],
-    each accessing 1 element as specified by wi_data=[1, 1].
+    XeGPU operations leverages LayoutAttr to distribute data across work-item. It is specified in tensor_descs
+    upon the tensor description creation. LayoutAttr contains the following parameters.
+
+    * scope: specifies the scope of current code. It can be either wg (workgroup), sg (subgroup) or wi (workitem).
+             it is hard required for subgroup, but optional for workgroup and wi. By default, if a LayoutAttr
+             contains sg_layout and sg_data, it will be treated as workgroup code; and if it only contains
+             wi_layout and wi_data, it will be considered as workitem level.
+    * sg_layout: [optional] specifies the total number of subgroups and their layout in a workgroup.
+    * sg_data: [optional] specifies the data size accessed per subgroup.
+    * order: [optional] specifies the dimension order used to linearize n-d sbugroup ids to 1-d.
+            The first dimension in the order list is the fastest-changing dimension.
+    * wi_layout: [required] specifies the total number of work-items and their layout in a subgroup
+    * wi_data: [required] specifies the data size accessed per work-item for a single distribution.
 
     `wi_data[0] * wi_data[1]` can be greater than 1, meaning that each work item operates on multiple elements,
     which is eventually lowered to "SIMT-flavor" vector, like SPIR-V vector or llvm vector, or packed to a storage data type.
     The multiple elements indicated by `wi_data` can only be from one dimension and must be contiguous in the memory along either dimension.
+
+    E.g., #xegpu.layout<wi_layout = [1, 16], wi_data = [1, 1]>
+    In this example, the subgroup has 16 work items in wi_layout=[1, 16], each accessing 1 element as specified by wi_data=[1, 1].
+
+    E.g., #xegpu.layout<sg_layout = [2, 4], sg_data = [16, 16], wi_layout = [1, 16], wi_data = [1, 1]>
+    In this example, the layout representing a workgroup work distribution. A workgroup has 8 subgroups organized as 2x4 layout.
+    and each subgroup accesses a 16x16 block per instruction, which is further disbributed to 16 work items as described above.

+    TensorDesc is a type designed to describe regions of interest in data, as well as some features
+    unique to Intel hardware. Unlike the built-in tensor type in MLIR, it essentially contains only
+    metadata and does not hold the data itself. It is primarily designed to support 2D block load/store
+    and DPAS (matrix multiplication instruction) on Intel GPUs. It encodes the following information:
 
     * shape:  the sizes/shape of the intereted data block, e.g., 8x16 means 8 rows
               and each row contains 16 contiguous data element. The rows could be
-              either contiguous or not, depends on whether the encoding attribute
-              is set or not.
-    * element_type: the data type of the data element, e.g., f16, f32.
+              either contiguous or not, depends on the encoding attribute. If the
+              encoding is a BlockTensorDescAttr, rows are contiguous. If the encoding
+              is a ScatterTensorDescAttr, rows are not necessary to be contiguous. If
+              encoding is not set, it is considered as a default BlockTensorDescAttr.
 
-    Similar to the builtin tensor, it also provides an optinal attribute to encoding
-    the following information via the TensorDescAttr object:
-    * memory_space (xegpu::MemorySpace): [optional] where the data is located,
-                global memory or shared memory. It is default to Global.
-    * array_length (int): [optional] The number of contiguous blocks with size as `shape`,
-               that will be loaded by block load at a time. It is default to 1.
-    * boundary_check (bool): [optional] indicates whether the operation detects the boundary
-                and pads with zero for out-of-boundary access. It is default to do boundary check.
+    * element_type: the data type of the data element, e.g., f16, f32.
