Hello Cristina,
The S32 and vtk6.2.4 support openCL 1.2/1.1 full profile but In short, the main differences here are in floating-point accuracy. In other words, the embedded profile need not adhere to the IEEE 754 floating-point specification, which may be a problem if you are doing lots of numerical calculations which rely on it. Quoted from the specification:
This relaxation of the requirement to adhere to IEEE 754 requirements for basic floating- point operations, though extremely undesirable, is to provide flexibility for embedded devices that have lot stricter requirements on hardware area budgets.
while desktop profiles must have a compiler available to compile OpenCL kernels, embedded profiles need not provide one. This can be seen through the clGetDeviceInfo documentation, which states:
CL_DEVICE_COMPILER_AVAILABLE: Return type: cl_bool Is CL_FALSE if the implementation does not have a compiler available to compile the program source. Is CL_TRUE if the compiler is available. This can be CL_FALSE for the embededed platform profile only.
Regards
