Hi All,

I have an Intel 3570k processor which has the HD4000 graphics built in, this supports OpenCL 1.2, wondered if you are going to do Apps that can use this. Not sure how much extra horsepower this would provide but seams a shame not to use it.

I think MW required DP. Does Intel HD support DP?

No, Intel HD 4000 does not support DP.

I have 2 PCs with an Intel GPU. Do you have plans about developing an app for Intel GPUs??

Currently there is no reason for them to develop it - the Intel GPU isn't capable of running the math for this project.

Intel GPUs support double precision ops starting from SkyLake.

Output from clinfo on i3-6100U (SkyLake series) shows that it has DoublePrecision support.

Here is an example output. Does it have enough features to be used by Milkyway@Home?
