Dear All,
1. I cross-checked the code for Mesh_XY.py and MeshDirCorners_XY.py file.
Where, in the MeshDirCorners_XY.py has the proper implementation of the
connected dir_nodes.
However, I couldn't find any code that connectes the dir_nodes with each
router inside the Mesh_XY.py file.
2. Now, as mentioned in the figure of Mesh_XY at homepage of garnet 2.0,
two links are connected between two routers (one incomming and outgoing).
However, if we see the below code for Mesh_XY, we can see both links are
connected to the same port number or string. Hence, it means as the
bandwidth factor is fixed, either one of the router can send a packet at a
time, not both.
# East output to West input links (weight = 1)
for row in xrange(num_rows):
for col in xrange(num_columns):
if (col + 1 < num_columns):
east_out = col + (row * num_columns)
west_in = (col + 1) + (row * num_columns)
int_links.append(IntLink(link_id=link_count,
src_node=routers[east_out],
dst_node=routers[west_in],
src_outport="East",
dst_inport="West",
latency = link_latency,
weight=1))
link_count += 1
# West output to East input links (weight = 1)
for row in xrange(num_rows):
for col in xrange(num_columns):
if (col + 1 < num_columns):
east_in = col + (row * num_columns)
west_out = (col + 1) + (row * num_columns)
int_links.append(IntLink(link_id=link_count,
src_node=routers[west_out],
dst_node=routers[east_in],
src_outport="West",
dst_inport="East",
latency = link_latency,
weight=1))
link_count += 1
3. I also like to know how much minimum clock cycle is required to transmit
a complete packet between the two interconnected routers.
4. And is it possible to make the packet level tracing in Garnet 2.0.
Please let me know the details to increase the understanding.
Thanks a lot in advance for your kind help.
Best regards,
F. A. Faisal
