How to create const vector variables(int4, float4, ...) in Kernel Builder

How to create const vector variables(int4, float4, ...) in Kernel Builder

Hi all,

Does any body know how to create const vector variables(int4, float4,...) in the Intel Kernel Builder? I had written a kernel with const vector variables and wanted to analyze it with Intel Kernel Builder. However I do not find a way to create vector variables and assign them to the kernel. Does any one know how to get this done? My kernel is written as:

__kernel void sample_kernel(__global uchar4* pTarget, __global uchar4* pSource, const int2 whSize, const float4 iColor)       { .... }

Hi freedayman,

You can assigne vector variables to your kernel like this : value1,value2,value3,value4

Hi,

In case you have a vector you want to assign, and it has repeating values (i.e. 1,1,1,1), Kernel Builder repeats the last value as many times as needed which might come in handy.

Also, here's a link to the user guide in regards to variables, which might be helpful:
