For GPUs it only really works because the code is translated to the relevant instruction steam close to the time of executing, where you can afford to optimize in a highly uarch specific way. Whereas VLIW at the time of itanium never was in that position... It just doesn't compute for me how Intel thought this was a good plan. It's not like they didn't know that existing compiled binaries are going to continue being used on newer uarchs
- p_l 3y agoThe critical part was less VLIW, and more EPIC - the Explicit Parallel part. There were previous VLIW arches that didn't have issues with compilers, one of them afaik even formed backbone of many advanced optimizing compilers in 1990s because the vendor licensed the compiler tech to others.
