<h2>Compute Model: Remote File Access</h2>
|
|
<p>
|
|
Output files can be designated as sticky but not
|
|
upload-when-present. Sometimes this is done because the file will be
|
|
used as an input for a later workunit; it may also be done to spread
|
|
large output data across participant disks, in cases where the data may
|
|
be too large to store on the project back-end.
|
|
</p>
|
|
<p>
|
|
To access such a file, the back end inserts a <b>file access
|
|
request</b> in the database. This specifies a file and a data-server
|
|
URL. When a host storing the file contacts the scheduling server (which
|
|
may not happen for a while) the scheduling server forwards the file
|
|
access request. The host confirms the file transfer when it is
|
|
completed; the back-end must poll for this event.
