@ilya @paul, so I moved to NERSC where Greg Daues is working successfully (and where we’d work to tie our prototype to the larger system,.) The good news is it works! (well almost). If Greg and l land on the same cluster head node, we conflict in /temp/fabric. (one of us owns the directory, the other cannot access it) I put a two line change fablib.py in my distribution to be sensitive to an environment variable to keep working. (see below with some surrounding lines for th change) I see there is a framework that tries to get FABRIC_LOG_FILE from a configuration setup, But FABRIC_LOG_FILE is not set-able from the environment. AFAICT.
is there a supportable way or me to change the logfile/data directory in the current code? If not are my changes useful to you?all in all this is working out very well for us.
LOG_LEVELS = {
‘DEBUG’: logging.DEBUG,
‘INFO’: logging.INFO,
‘WARNING’: logging.WARNING,
‘ERROR’: logging.ERROR,
‘CRITICAL’: logging.CRITICAL
}default_fabric_rc = os.environ[‘HOME’] + ‘/work/fabric_config/fabric_rc’
default_log_level = ‘DEBUG’
default_data_dir = os.environ.get(‘FABRIC_DATA_DIR’,’/tmp/fablib’) #change near line526 fablib.py
default_log_file = os.path.join(default_data_dir,’fablib.log’) # changefablib_object = None
ssh_thread_pool_executor = None
no, the test is
two nodes at NCSA,
two at TACC. Each with
a L3 IPV4 network
after the submit, I go to set up routes so that all nodes talk to all other nodes.
When I get the network object to find things I need for routing the network.get_gateway() and network.get_subnet() calls give the errors like
(Pdb) network.get_subnet()
WARNING:root:Failed to get layer: ‘str’ object has no attribute ‘layer’It broke on Friday, so I suspected a change in the downtime, but after Greg and I worked together today, I see the software still works at NERSC, so I am beginning to wonder about my (rickety) python install on my mac… So let me clean house a bit and see what I learn.
Similarly, I am working with the libraries on Linix/MAC. I had working code break as of Friday.
the submit emits errors:
WARNING:root:Failed to get layer: ‘str’ object has no attribute ‘layer
My attempt to set a route after submit
(Pdb) network.get_subnet()
WARNING:root:Failed to get layer: ‘str’ object has no attribute ‘layer’I’m no expert, but the network.slice.slice is serialized java and looks like all the network provisioning was done on the server, but maybe on Friday, there was a change on the FABRIC server-side on how all this was serialized when it was sent to the client, and not it’s not de-serializing?
