ASTRA-Sim: Quick Example

Run Astra-Sim with a quick example (Ring_allgather_16npus.sh): This example demonstrates a ring all-gather operation on 16 NPUs connected in a ring topology. Please go back to build up the necessary dependencies before running the example. The following shows the expected output:

 1[system::topology::RingTopology] [info] ring of node 0, id: 0 dimension: local total nodes in ring: 16 index in ring: 0 offset: 1 total nodes in ring: 16
 2[system::topology::RingTopology] [info] ring of node 0, id: 0 dimension: local total nodes in ring: 16 index in ring: 0 offset: 1 total nodes in ring: 16
 3[system::topology::RingTopology] [info] ring of node 0, id: 0 dimension: local total nodes in ring: 16 index in ring: 0 offset: 1 total nodes in ring: 16
 4[system::topology::RingTopology] [info] ring of node 0, id: 0 dimension: local total nodes in ring: 16 index in ring: 0 offset: 1 total nodes in ring: 16
