    <p>OpenCL is supported by both main GPU manufacturers and is by far your best bet. The other alternative is CUDA. I think you would be better off asking a question along the lines of "How do I solve this problem using OpenCL?" than simply stating that it is not suited for the work you need done, as it is very hard to make recommendations based solely on the description above. </p> <p>Please also note that OpenCL supports an embedded profile, which means it has some support on mobile devices. However the iPhone does not currently support this. It was <a href="http://iphonedeveloperjournal.com/2012/04/18/a-prediction-for-ios-6-a-new-public-framework-opencl-2/" rel="nofollow noreferrer">rumored</a> that it would be coming to iOS 6 but this seems not to have happened yet. Also see <a href="https://stackoverflow.com/questions/9005352/how-to-use-opencl-on-android">this question</a> which explains how android and OpenCL function together.</p>

    1. COThank you for your input. I need support on mobile devices which as of now I don't see possible with OpenCL. Although [PGCL](http://www.pgroup.com/products/pgcl.htm) seems to have some very promising news in this field, I still feel that OpenGL has far more support even though it is quite different from what I am looking to achieve.

    2. COI worked with a researcher who was doing work in the field of using OpenGL as a computing language, a few years back. However, all work was dropped in favor of CUDA when it first came out. It seems kind of strange to me to want to use a highly parallel language for high performance computing on a mobile device, although I can see a few uses.. Are you sure this is really what you need? Can you elaborate further on your actual needs? Have you considered streaming the dataset to a server that offers OpenCL instead of consuming all the power on the mobile device in question?

    3. COI'm essentially trying to create an "engine" that runs on multiple platforms that runs mathematical equations on the gpu. I have this created for the CPU, but I'm trying to port over some of the functions that take up the most time. On mobile devices it is incredibly slow to the point where it is unusable if certain functions are used. I am trying to run these very large loops on the GPU and maybe use the GPU for even more of the processing if it seems logical. It would be possible to program several engines for different platforms, but I'm trying to avoid that since I'm just one person.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
