installed libfabric 1.6 or higher library - see https://ofiwg.github.io/libfabric/

pthread and openmp libraries are still included in makefile but are probably save to remove as they are not used anymore.

simple list of hostnames that act as servers/processing nodes. each line may hold one adress. '//' will tell the parser to ignore this line

current implementation assumes static client/server relationship and requires this file to find servers. Future implementation may run multi purpose nodes from central node. Removing the need for this file.

I recommend starting up servers and clients through slurm scripts. For the above example scripts a number of options need to be provided as these settings will likely vary from system to system:

#path, if Benchmark is not run properly from path it won't find config files.

cd <PATH TO '.../CBM_Benchmark/'>

#match servers/clients _num in conf

SERVERS=5 / CLIENTS=5

#declare an array variable. the names inside this list need to match the slurm names of the hosts listet in serverlist

declare -a nodes=(pn16 pn17 pn18 pn19 pn21 pn22 pn23 pn28 pn29 pn30 pn31 pn32 pn33 pn34 pn37 pn38)

this Benchmark comes with various settings. the default settings should support a network of 10000x10000 nodes. [required] indicates that this field will most likely always need to be adjusted according to the network setup:

//port settings [required]

//client_port:[10000-19999], server_port:[20000-29999], controller_port=[30000-49999]

start_port=10000

controller_port=30000

server_offset=10000

//adress of the controller node [required]

controller_addr=10.1.103.102

//the size of each message. note this is not the MTU(payload) transmitted with each packet

//it is recommendet to keep this above the MTU

msg_size=4096

//define number of nodes [required]

num_en=5

num_pn=5

//duration of the benchmark in seconds

max_duration=40

//time interval between each data snapshot in seconds

checkpoint_intervall=10

command: ./Benchmark <cn/pn/en> <node_id>

run './Benchmark cn 0' on node with controller_addr.

then run './Benchmark en <0:N>' and './Benchmark pn <0:N>' - see runServers.sh / runClients.sh

Note: Benchmark assumes id format [0:n] port numbers are calculated based on node id. The processing nodes(pn) id must match the order of the serverlist.

results will be printet into file './[Weekday] [Month] [Day]' with format:

en_id pn_id num_en num_pn delta_sec time_sec completions msg_size[byte] total[byte] total[Gbit] throughput[Gbit/s]
