I'm interesting in JPPF from start and I keep your fingers crossed. But I don't have enough time to dig deep into usage of JPPF.
  I work for company that develops special software in Java SE. And maybe will need some distributed computations. I know that you have distributed class loader that is exactly what we need.

Best scenario for us to distribute computing:
  Our users are in office with several computers, server(s)
  Any desktop computer can be used as computation node / computation server (source)
  Data locality and sharing between tasks on computation node (we have ~10-~100MB data blocks) So even on 1GBit network can be slow.

So it would be handy to
  *) autodetect available computing nodes (black/white list) on local network.
  *) compute node - (windows/linux service or web start application - already done)
  *) simple local monitoring - in tray icon (allow to pause computation, status, ...) - I think it is possible to with current state of JPPF (strip admin console)
  *) computation server (source) as part of our desktop application (not separate JVM)

These are just my toughs about future of our software. And maybe it is different way how to use JPPF than you've planned.

Hello Martin,

Thanks you very much for these interesting suggestions.
I would like to register feature requests for some of them (those that are not already present).
Would you mind elaborating a little on the following:

autodetect available computing nodes (black/white list) on local network

what do you mean exactly by black or white list?

simple local monitoring - in tray icon (allow to pause computation, status, ...) - I think it is possible to with current state of JPPF (strip admin console)

2 things here: the system tray functionality only comes with jdk 1.6 or later, so this functionality would not be available in jdk 1.5. What which part of the admin console would you strip down for that?

computation server (source) as part of our desktop application (not separate JVM)

Can you please give a little more details about this? what do you call the "computation server"?

Thanks you very much for your time,
-Laurent

*) autodetect available computing nodes (black/white list) on local network
  I'm sorry - its my fault. - I meant autodetect running servers. That are available on network (now I have to enter IP address).
    (black/white list of allowed IP ranges. There is possible to run multiple servers on local network.

*) simple local monitoring in tray
     Just to allow user on computing node monitor locally if is it working, allow him temporary disable node from computing network to maximize local performance.
     This can be very simple application. Not as task monitor. (I think this is special extension than can be made by myself). Yes tray support (port from JDIC) is in JDK6.

*) computation server as part of application - my fault. I misunderstood architecture of JPPF.

I try to watch upcoming java releases and JSRs to be able to design applications for simplier transition to latest version.

PS please can you use faster LaF. when you use -Dsun.java2d.trace=,count you will see lot of software rendering (sun.java2d.loops...)

Hi Martin,

autodetect available computing nodes (black/white list) on local network

Thanks for the clarification. I registered a feature request for this:
2182002 - Automatic detection of running servers

simple local monitoring in tray

Thanks again. I registered it as a feature request:
2182052 - Simple local node monitoring in system tray

By the way, you can enter feature requests yourself, if you have a SourceForge.net account and you feel comfortable with doing that.

PS please can you use faster LaF. when you use -Dsun.java2d.trace=,count you will see lot of software rendering (sun.java2d.loops...)

You can already do that, by using the -Dswing.defaultlaf= JVM option for the GUI. For instance, on a Windows system:

Code: [Select]

-Dswing.defaultlaf=com.sun.java.swing.plaf.windows.WindowsLookAndFeel
Sincerely,
