Graal and Clojure

[Caspole, Eric]

Hi Jules,
I updated everything and got Clumatra running on the real hardware today.

In project.clj, I used this:

  :jvm-opts ["-server" "-ea" "-esa" "-Xms1g" "-Xmx1g" 
             "-verbosegc" "-G:Log=CodeGen"
             "-XX:+GPUOffload" "-XX:+TraceGPUInteraction"]

Then make sure your /path/to/okra/dist/bin is in the PATH and LD_LIBRARY_PATH.

When it is using the simulator, you will see this:
[HSAIL] using _OKRA_SIM_LIB_PATH_=/tmp/okraresource.dir_2595501614013009358/libokra_x86_64.so

With hardware or external okra you will see this:

[HSAIL] library is libokra_x86_64.so

Regards,
Eric

Eric,

I just checked support to Clumatra for running individual unit tests
from the CLI - should be enough to get you set up with your debugger.

All details at the bottom of the README.

https://github.com/JulesGosnell/clumatra

I'm afraid you will need to install maven if you don't already have it -
for some reason lein does not seem to have a test-jar target.

It is still a little rough around the edges, but better than nothing :-)

I also just bought my HSA h/w - should be up and running next week
sometime. Did you figure out how to enable native-mode Okra ?

catch you later,


Jules
