Hello Simon,

I'd really like the few additions I have worked on for OpenCL package to end up in CRAN. We discussed in the past and it seemed the mean complexity was that my work was on a git outside of GitHub. I also noted you wanted (for very good reasons) that my proposed commits to be as atomic as possible and with focused objectives each of them.
I am proposing the these two first commits : here are what they are performing :

1. https://github.com/s-u/OpenCL/tree/a7071085f3e3ea35cc2909c91190fa8d55657ebf is just adding some extra information to the oclInfo call on a device. In particular it gives access to some memory and image capabilities of the OpenCL device. There is also a way to set default platform/device (through defaults getOption("ocl.default.platform") and getOption("ocl.default.device").
2. It handles in a better way the case that there is more than just one available platform on the coputer. In such case, oclDevice (without providing a platform) will scan all devices of all platforms instead of scanning only the devices of the first platform (which might be 'pocl', and as such would not have any GPU device).

I really hope you can accept these pull request. To my knowledge this should not break any of the existing code/API.

If this way to work is ok with you, and you find my proposal of sufficient quality, I'll go on adding support for OpenCL images.

Currently I have two other computation intensive package I can not push to CRAN because they rely on some of the extensions I have coded in OpenCL.

Cheers,

Serge.

Sorry Simon,

I should have checked before the commit and pull-request… there was a left over from the rebase conflict resolution. This is corrected in commit 1e17e8c.
