topology for node xl170, d6515 and c6525 in utah

[Junhua Yan]

Hello,

Is it possible to learn the actual topology information for node xl170, d6515 and c6525 in Utah? For example, which nodes are under the same experimental/spine switch.

I am studying the networking behaviors for each pair of nodes under different communication patterns and the topology information will help understand the results.

Thank you!

Best,

Junhua Yan

Hi. I will try to pull this info from the DB and get it to you today.

Hi, see the attached image.

Thanks for sharing this Leigh,

Are you aware of a way to request nodes under different switches when creating profiles?

I was only able to find setNoInterSwitchLinks() to request nodes under the same switch.

Thanks,

Junhua

So for a small experiment you can do something like this:

https://www.cloudlab.us/p/testbed/specific-switches

but there have to be free nodes connected to the switches you
specify in the profile. You can see what nodes are free by looking
at this page:

https://www.cloudlab.us/cluster-status.php?cluster=Utah

Not many nodes free at the moment. Please note that the reservation
system is not much use in a case like this, since you cannot reserve
specific nodes.
