In-Reply-To: References: Message-ID: 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. -- Tom > -----Original Message----- > From: sumatra-dev [mailto:sumatra-dev-bounces at openjdk.java.net] On Behalf Of > Ret Trinity > Sent: Thursday, April 30, 2015 3:05 PM > To: sumatra-dev at openjdk.java.net > Subject: Greetings; state of Graal support for HSA? > > We just got started trying to use Sumatra on a test partition (we've > previously been using aparapi-lambda; it's a bit buggy and crash-prone). > Sadly, all our attempts to build a JVM have resulted in functional JVMs with > no support for -XX:+GPUOffload (or any of the other switches needed for > Sumatra to work). > > We found the February 2015 mailing list archive about Graal pulling support > for HSA, so we used the recommended version of Graal from January 2015 that > is supposed to provide the necessary HSA support for building the > Sumatra/Graal VM: > > http://hg.openjdk.java.net/graal/graal/rev/91fee1fab96d > > Doing so did not help.
