DIMES for ARM?

[KenSharp]

Hi,

I was going to see if the DIMES source would build on ARM, but do I even need to build anything? It seems to be mostly Java so, in theory, it should run on any architecture that has a Java VM. Can anyone point me in the right direction as I can't see a build tree in the source?

Thanks

Certainly looks like I jumped the gun a bit there: Debian doesn't appear to have a (full) ARM implementation of Java. I'm not sure if Ubuntu has but I'll look at this again later.

The Sun site is always a minefield, and it doesn't look like they have a prepared JVM for ARM/Linux.

I have installed the ARM version of Java from Sun. I tried the headless version and it caused an exception (sorry, didn't take a dump of the output). Tried again with the headful version which nicely points out that there is no X11 installed (I'm running a chroot over SSH).

Is there any way to set the options and get the DIMES Agent to run headless? A full X11 install seems very wasteful, and might not even work.

I will point you to the same answer I wrote about the iMac. We are in the process of working on a new version of DIMES that will de-couple the GUI from the core measurement engine. That should solve the problem you are presenting.
We're a few months away from the release, but if you'd like I can probably send you a n alpha version to try. It will not have a gui application, but if you run it from the command line you should be able to see outputs. Let me know if this is something you are interested in trying out.

The storage card for my device just failed and I don't have a spare!
I've ordered a new one so I'll be back later, but I am of course interested in the CLI version.

[KenSharp]

Well my system is back up and running so if you're still after an alpha tester I'm ready to give it a go!

Ken,
Right now we're working on restoring our servers after a major meltdown, but hopefully we can take you up on this offer soon.
Thanks
