Greetings; state of Graal support for HSA?

[Deneau, Tom]

Ret --

Sumatra is not in active development for now.  OpenCL based aparapi
https://github.com/aparapi/aparapi may meet your needs but the API
does not support lambdas.  

I believe the aparapi.lambda branch at https://github.com/aparapi/aparapi.lambda
is also not in active development.
