When the Itanium was developed and introduced (2001), nobody was thinking about general-purpose computations. DirectX 8.0, which introduced Shader Model 1.1 (which was far away from being suitable for GPGPU; Shader Model 1.1 was rather about strongly (also size-)limited programs for the vertex and pixel processing stage), was only introduced in 2000, the first release of CUDA was in 2007, and the first release of OpenCL was in 2009.
Yes, but even farther back. Apparently the Pentium Pro team was forked off to work on Itanium in the mid 90s. At that point a GPU was at best just the rasterizer and ROP phases from an acceleration perspective.
