I suspect the first generation won't have much support for rescheduling, but hopefully I'm wrong. I'd bet the pressure from the graphics side will prefer using space for execution units over saved contexts. > The Tera machines did have dynamic hardware thread scheduling. > But I think they were less dynamic than AMD's GPUs are. Do you mean the MTA seems less dynamic than the GPUs? No. Far more so simply by working only with single streams (one-wide wavefronts). But if you mean the X1's less dynamic than the GPUs, then almost definitely so long as AMD actually implements the possibility. I'm more curious to see what they learned from the Cray software environment, given that the X1 had one somewhat underpowered sequential CPU coupled to the vector units. I don't expect direct cross-pollination considering Cray's chosen nVidia as their partner in GPU-ish work. -- Jason
