Graal and Clojure

[Eric Caspole]

Hi everybody,
I was setting up a new HSA system today and I installed Clumatra and got 
it working under the simulator. I have a real HSA system not too 
different from this:

http://code.google.com/p/aparapi/wiki/SettingUpLinuxHSAMachineForAparapi

In the clojure/lein/maven based system there is so much harness I can't 
immediately see how to switch in the real hardware version of Okra 
instead of the simulator Okra that gets installed into maven and 
exploded in /tmp when the tests run.

Jules, could you show how to bypass the harness etc to switch the Okra? 
Can I just run 1 test with a simple java command line? This makes it a 
lot easier to use a debugger which I will definitely want to do.

Otherwise this is a cool project and we already found 1 or 2 issues we 
can fix in HSAIL Graal related to your clojure tests.
Regards,
Eric

This actually makes the value of having Clojure tests integrated into our gate system somewhat problematic - debugging/fixing failures may be difficult. I’d suggest you report failures your discover on the sumatra-dev and graal-dev lists and we can resolve them that way for now.

It seems unnecessary to duplicate all your tests in Clojure, since you are already guarding against regression in these areas - I think I will start out with a fairly general set of tests as I probe for particular problem areas for Clojure, into which I may dive for more detail - time will tell... if you have any ideas, please let me know.
