Carl has requested that ISI help OSU integrate their Datacutter product with
the Globus Toolkit. They have a specific problem with the gram client
library that is blocking their progress. Details below.

Just finished a con call with OSU re datacutter/Globus integration. These
guys are sharp and have a very good sense of what needs to be done.

They need some help from an engineer to trouble shoot a problem in getting
their sample code that uses the gram client library to execute a process on
a remote host. They are willing to post messages to the globus list for
help, but think this one could use some extra attention. They have globus
installed and working in the lab, globus-job-run works. Found some sample
gram client code and can't make it work. getting an error code 10, which
globus site says is most likely and auth(z) problem, it suggests checking
the gatekeeper log, but their log shows success for auth(z). not sure what
to do next.

Integration points:
* currently use ssh to startup console processes on different hosts; want to
transition to gram
* communication layer: currently insecure; want to use GlobusIO and gsi
security
* Discovery: currently their processes register with a deamon for discovery,
will consider also publishing this info into MDS, but were more hesitant
about this - don't yet understand the value of doing so. I'll keep working
this one.
* Mentioned to them the possibility of integrating with GridFTP and the
replica management technologies (not unlike their current SRB integration
project), they are open to exploring this, but want to knock out the above
items first.

    Does anybody know if globus i/o has an equivalent function to the 
select function, or if one can get a handle to the underlying file 
descriptors?
