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

Jzhan59 — Wed, 28 Aug 2013 02:40:13 GMT

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,

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:
