You can actually use OpenCL with a virtual machine. I've started doing this lately for testing clover, which is an Open Source OpenCL implementation for AMD GPUs. There is one annoying issue that on some AMD hardware, you can only boot the guest once per host boot, so if you want to reboot the guest you must also reboot the host. Otherwise things seem to be working fine, at least with clover. I'm working on a guide for how to set this up in case anyone is interested: http://dri.freedesktop.org/wiki/PCIPassthrough/ -Tom > Florian > > Am 17.12.2014 01:33, schrieb Qichang Liang: > >Currently I am working on MacbookPro Retina installed with OS X 10.10. > >I have a VMware virtual machine on my USB 3 hard drive, which I can > >run using VMware Fusion 7.1 > > > >However for correctness and performance testing, which option is the best? > > > >* compile the gegl directly on OS X (which I can't get it compiled) > >* compile on a Linux VM that runs on VMware Fusion 7.1 > >* install Linux on my USB hard drive, boot my retina macbook from the > >Linux USB hard drive and compile from there? > > > >I don't know whether I can really test performance of OpenCL in a VM. > >Also both the USB HD and the retina support USB 3, so in this case, > >will the hard disk no longer be the bottleneck? > > > > > >On Tue, Dec 16, 2014 at 8:38 PM, Alexandre Prokoudine > ><alexandre.prokoud...@gmail.com> wrote: > >>13 дек. 2014 г. 10:56 пользователь <kcle...@users.sourceforge.net> написал: > >>>Hi! > >>> > >>>I have just learned OpenCL programming, and would like to get solid > >>>experience in OpenCL.
