Subject: Re: openmpi/opencl best practices
Hi Dan,
Have you looked at VCL to achieve the OpenCL clustering? While I did not use it myself, I’ve seen some success stories and howto on the web. I believe the VCL will allow you to have a heterogeneous setup. Not sure if the cluster will work with the Laptop + EC2 instance connectivity, I assume that thing will use multicast to manage the node memberships.
