Description (last modified by lnevers@bbn.com)

Background: Listresources showed large number of pcvm slot counts available before the test:

  • pc5 had 97 slots
  • pc3 had 100 slots

Test sequence:

  1. Created 1 sliver named 25vmslice1 with 25 VMs without problems, with the following allocation: 10 VM on pc5, 10 VM on pc3 and 5 VMs on pc4.
  1. Created a second sliver named 25vmslice2 with 25 VMs which caused the following error:

Another instance of the assignment failure occurred while running a 10 experiments with 10 VM test. Test was started with plenty of resources available (pc5 had 97 slots and pc3 had 100 slots). Here is the sequence of events and allocation based on sliverstatus:

  1. Setup 1st sliver 10vmslice1 - OK - Allocation: 10 VMs on pc3
  2. Setup 2nd sliver 10vmslice2 - OK - Allocation: 10 VMs on pc5
  3. Setup 3rd sliver 10vmslice3 - OK - Allocation: 10 VMs on pc5
  4. Setup 4th sliver 10vmslice4 - OK - Allocation: 10 VMs on pc5
  5. Setup 5th sliver 10vmslice5 - OK - Allocation: 10 VMs on pc3

So here is the issue; Creating a 10 node mesh of 100Mb links requires an aggregate bandwidth of 1GB. Not cause you are going to actually use that, but the resource mapper cannot make any assumptions in the absence of other information.

This is why you get to provide a bandwidth in your rspec, to inform the mapper what you really want to do.

Diving deeper for those who are interested; this is a lan of containers on the same physical node, and there is some limit to the amount of traffic that can be sent over the loopback device between containers. At some point the physical node will no longer be able to keep up, and so we set a limit on what you can ask for. At the moment that number is set a lower then it probably should be (at 400Mb).

Bottom line; I bumped that to 1Gb which should allow your rspec to map. These nodes are pretty beefy, so I imagine they can keep up.

Lbs

The message reported to the experimenter is somewhat cryptic and I missed the bandwidth violation which was on line 25 out of 145 lines (not including the omni output).

I realized we are still developing/debugging, but I am going to ask anyways... Are there plans to modify results to provide a more intuitive output?

Re-ran the 10experiments with 10 VMs assuming that the configuration changes from last Friday would handle the bandwidth requirements. Before starting, verified that both shared nodes had 99 slot available.

Set up the first 8 experiments without problem. On the createsliver for the 9th experiment (10vmslice9) fails with this error:

Here is the VM allocation for the 10 experiment with 10 VMs each, in case it is of interest to anyone:

  • 10vmslice1 - 10 VMs on pc5
  • 10vmslice2 - 10 VMs on pc3
  • 10vmslice3 - 10 VMs on pc5
  • 10vmslice4 - 10 VMs on pc3

With the following resources available:

Tried to create one sliver with 20 nodes (20vmslice1), which resulted in the same failure reported yesterday afternoon due (desires:1).
