The Open Cloud Testbed (OCT) workflow consists of two parts.
1. Development: OCT development tools are available on build machines that can be allocated as virtual machines (VMs) within a CloudLab experiment. Users can remotely log in to these VMs to build FPGA bitstreams and host executables.
2. Deployment: After creating the bitstreams/host executables, users will use CloudLab for targeting. OCT currently consists of 24 AMD Alveo U280s, 4 AMD VCK5000s, 4 AMD V70s, and 2 NVIDIA V100 GPUs. The U280s and VCK5000s are connected to 100 GbE data center switches using QSFP28 passive DAC cables.
The table below shows the hardware available in OCT along with the host nodes.
| Hardware | Nodes |
|---|---|
| U280 | pc151-pc175 |
| VCK5000 | pc176-pc179 |
| V70 | pc180-pc183 |
| V100 | pc178-pc179 |
All nodes are equipped with 40 GbE regular NICs. In addition, pc160–pc163 also have 100 GbE NICs for high-bandwidth networking.
We have created the CloudLab profiles oct-u280, oct-vck5000, and oct-v70 to help users select nodes with the specific resources they need.
