What do you consider a Kepler core? The Epiphany cores are dual issue RISC processors that run independent C/C++ tasks.
- DeepDuh 14y agoKepler has 8 "SMX" with 196 parallel sp threads each. For me the number of cores = the number of parallel threads, although on GPU they are not as independent, i.e. each "core" of an SMX either executes the same instruction on adjacent data or does nop. With dual issue do you mean a two stage pipeline or two threads in parallel, both performing FLOP?
- sparky 14y ago"Dual issue" means "can issue two instructions per cycle", independent of pipeline depth or multithreading. In the case of the Epiphany, it can issue an ALU instruction and a floating point instruction each cycle.
