Thread-topic: Large reused files
Hello,
I've been reading
about Xgrid and tinkering with other people's software, but am only beginning to
write my own so my apologies if this question is a bit
basic....
I am developing a
distributed calculator, probably as a Cocoa app. The "agent tool" is a
simple command-line tool and is quite small (<200k). This command line
tool uses a precomputed data file (~10MB) for speed. This data file is
unchanged for each "run", but does change between runs. (Ex. All
calculations on Helium use one file, Nitrogen another).
I'd like to not
require manual installation of this file on target computers. On the other
hand, my grid is small (6 CPUs) so its likely each computer would reuse the
file, so it seems a bit wasteful to retransmit the same file every time an agent
gets a task. (I expect each "run" to consist of 500-1000 agent tasks at
about 1 hour each).
How can I set up the
system so that this 10MB file is sent to an agent only if the agent does not
already have it? Does Xgrid support such semi-persistent storage?
(Obviously I'd also like each agent to remove this file once the entire job is
complete.)
