It worked after manually doing the steps you described. Thanks.

I have booked a slice ( d6065a22-c893-425f-b12f-3bc0fe4d2481 ) with NEWY and CERN nodes which are listed as 320Gbps. This time, it did not get stuck. Everything went smoothly. I am still getting around 3 Gbps.

Could you please have a look?
I saw that there is another 8 Gbps line listed for (NewY, CERN). Can you guide me on how to pick sites so that I can get the fastest network speed?

(‘NEWY’, ‘CERN’)

Your provided snippet gets stuck at the ‘make’ command in both of the nodes:

ubuntu@Node-GATECH:~/iperf-3.18$ make

One thing I forgot to mention is the execution often gets stuck in slice submission cell. Like, post boot config of one node is usually done but the other gets stuck. It gets stuck at this point, FIU’s node does not deliver the ‘done!’ message:

Time to StableOK 246 seconds
Running post_boot_config ... 
Running post boot config threads ...
Post boot config Node-GATECH, Done! (16 sec)

Here’s the code:

sites = ['GATECH', 'FIU']
print(f"Sites: {sites}")

node1_name = 'Node1'
node2_name = 'Node2'
cores=8
ram=64
disk=1000
image='default_ubuntu_20'

slice_name = 'iPerf3-tuned-nic-x6-64gb-1tb-GF-2'
nic_name = 'nic1'
model_name = 'NIC_ConnectX_6'
network_name='net1'

from ipaddress import ip_address, IPv4Address, IPv6Address, IPv4Network, IPv6Network

subnet = IPv4Network("192.168.1.0/24")
available_ips = list(subnet)[1:]

#Create Slice
slice = fablib.new_slice(name=slice_name)

net1 = slice.add_l2network(name=network_name, subnet=subnet)

for s in sites:
# Node1
node1 = slice.add_node(name=f"Node-{s}", cores=cores, ram=ram, disk=disk, site=s, image=image)

iface1 = node1.add_component(model=model_name, name=nic_name).get_interfaces()[0]
node1.add_component(model='NVME_P4510', name='nvme1')
iface1.set_mode('auto')
net1.add_interface(iface1)
net1.set_bandwidth(50)

node1.add_post_boot_upload_directory('node_tools','.')
node1.add_post_boot_execute('sudo node_tools/host_tune.sh')
# node1.add_post_boot_execute('node_tools/enable_docker.sh {{ _self_.image }} ')
# node1.add_post_boot_execute('docker pull fabrictestbed/slice-vm-ubuntu20-network-tools:0.0.1 ')

#Submit Slice Request
slice.submit();

I have to stop the execution and move to the next cell. I’ll report here what I get after running the esnet iperf3. Let me know if you need anything to investigate this issue.

It’s working now.

Thanks,

Could you please share your slice ID?

I have tried again, this time without any modifications to the original notebook, but I still got the same error.

Hi Komal,
Here is the slice ID: f05dedc0-468f-406e-a566-8041d507ad60

I am trying to transfer some files from MASS to TACC but it is failing to find any route.

 

Here is the notebook that I used: https://github.com/swargo98/LLM-based-Data-Movement-Optimizer/blob/main/iperf3_optimized_w_error.ipynb

[Rasman Mubtasim Swargo]

Sorry, I could not upload the notebook as the file type is not supported.

Here is the github link of the notebook: https://github.com/swargo98/LLM-based-Data-Movement-Optimizer/blob/main/iperf3_optimized_w_error.ipynb
