Hi all,
Here is the latest status of the mdsplus/globus infrastructure for
the demo.
What is working:
Controller:
The controller now cycles between three efit shots (shot numbers
1-3). The controller script can take two optional parameters: the
data_server and the compute_server hostnames. The controller now does a
globus-job-submit command to the compute_server to start the efit
application. It passes to this efit script environment variables:
shot_number, data_server and mds_event_target. The efit application
needs to connect to the data server, open the appropriate efit tree
(using shot_number) and write the results. The efit script should then
do an: setevent EFIT_DONE.
Data servers:
Data servers can now be run on both diesel.lbl.gov and
clipper.lbl.gov (and on natasha.lbl.gov on the demo floor if you loose
connectivity to lbl). I have changed the client authentication code to
use MODE_IDENTITY and hardcoded in the identity string of a data server
certificate Mary generated for me. (This will eventually be replaced by
a MODE_CALLBACK which will examine the server identity.) I have
experimented with using globus-job-submit to start these servers. It
works but we will need to have gridmap entries for the certificate you
will use for the demo on the server hosts which will map to an account
which has write access to the data files.
Compute server:
I have a dummy efit job on dg0n7.mcs.anl.gov which successfully runs
via a globus-job-submit command from the controller.
To be done:
Controller:
1) Add picture of fusion experiment control room (C-Mod possibly).
2) Hook up real visualization (either done in IDL or the fancy
version if ready for the demo).
3) Use globus-job-submit, globus-job-cancel and globus-job-clean to
start all mdsplus servers used for a demo. This will need appropriate
gridmap entries mentioned above.
4) Perhaps add infovis database commands to drive infovis display.
5) Install on anl's demo floor workstation.
Data servers:
Essentially complete. Perhaps additional backup data server hosts?
Compute server:
1) Change to use real efit analysis code. gridmap to demo user
account. Single processor/multi processor options?
2) Add backup compute server hosts?
