Setup

Change cx5_IFACE and FPGA_IFACE properties with correct interface names in sandia-experiment/scripts/setup/ip_interface.config file

Only for CX5 run this - (on both sender and receiver)

./scripts/setup/install-dependencies.sh

Setting up CX5 with filters and cluster mode - (on sender)

./scripts/setup/sender_setup.sh -n cx5 --add_filters --cluster_mode

Setting up CX5 with cluster mode - (on receiver)

./scripts/setup/receiver_setup.sh -n cx5 --cluster_mode

Setting up FPGA with filters and cluster mode - (on sender)

./scripts/setup/sender_setup.sh -n fpga --add_filters --cluster_mode

Setting up FPGA with cluster mode - (on receiver)

./scripts/setup/receiver_setup.sh -n fpga --cluster_mode

If you want to add dummy filters for FPGA for performance enhancement. This will add 2000 dummy rules. (On sender)

./scripts/setup/dummy_filters.sh -n fpga

Run experiments

Describe your experiements in a json file (sandia-experiment/workloads/template.json) and run

python3 workloads/run_experiments.py template.json

  • There are three modes

    • CLUSTER
    • NORMAL
    • IP

  • Cluster mode behaviour

    • One to one mapping between clients and servers
    • Number of clients and servers will be based on "parallel" property. "clients" and "server_instances" properties are ignored.
    • Virtual IPs will be taken into account. Virtual IPs are calculated based on the first IP address provided in "server_list" and "client_list". This assumes that the NIC is configured with multiple IPs.

  • Normal mode bahaviour

    • IP list is ignored.
    • Servers and clients are distinguied only by the ports and will have the same IP (first IP) specified in "server_list" and "client_list".
    • If there are more clients than server instances, clients will pick servers in a round robin manner
    • If there are more servers than clients then there will be idle servers

  • Other requirements

    • Control node should have access to all clients and servers.
    • Control node can behave as one of the clients.

Workloads

  • NOTE: Memcached experiments assume that the memcached server is up and populated with data. Instrcutions on setting up memcached can be find in sandia-experiment/workloads/memcached instrcutions.md file.

Experiment Analyzer

  • Generic Analyzer (Use this as the base analysis script when developing specific analyzers)

    • analysis/analyzer.py

  • Iperf throughput

    • python3 analysis/iperf_stats.py "file_pattern" "tar_location" "process_location"
      • eg: python3 analysis/iperf_stats.py "Exp0-r0--iperf-20220818T143252" "/tmp/data-raw" "/tmp/data-processed"

Other Scripts

[Only when you need individual scripts instead of going with the default cluster setup]

Regardless of the NIC type - Generic performance tuning (On both sender and receiver)

./scripts/setup/setup-generic.sh

Change network settings (only for FPGA) on both sender and receiver

./scripts/setup/network_settings.sh -n fpga

Setting up IPs

  • Edit ip_interface.config with relevant values

on sender CX5

./scripts/setup/setup-ip.sh -n cx5 -h src 
./scripts/setup/setup-ip.sh -n cx5 -h src --assign-multiple-ips

on receiver CX5

./scripts/setup/setup-ip.sh -n cx5 -h dst
./scripts/setup/setup-ip.sh -n cx5 -h dst --assign-multiple-ips

on sender FPGA

./scripts/setup/setup-ip.sh -n fpga -h src 
./scripts/setup/setup-ip.sh -n fpga -h src --assign-multiple-ips

on receiver FPGA

./scripts/setup/setup-ip.sh -n fpga -h dst
./scripts/setup/setup-ip.sh -n fpga -h dst --assign-multiple-ips

Settings up filter rules

on sender

./scripts/setup/remove_filters.sh -n cx5
./scripts/setup/remove_filters.sh -n fpga
./scripts/setup/add_filters.sh -n cx5
./scripts/setup/add_filters.sh -n fpga

Enable XPS

./scripts/setup/enable_xps.sh -n fpga
./scripts/setup/enable_xps.sh -n cx5

Disable XPS

sudo ./scripts/setup/xps_setup.sh --dev ifname --default --disable

Add dummy rules

on sender

Edit sandia-experiment/scripts/setup/ip_interface.config with relevant values

./scripts/setup/dummy_filters.sh -n fpga
./scripts/setup/dummy_filters.sh -n cx5
