Oh yeah! I mean to be fair, it was a full-fledged PowerPC single core in its own right. I'm pretty sure that generation had AltiVec (simd instructions), so you could theoretically do some number-crunching on it as well, but it had plenty to do already with managing memory I/O. And actually also network I/O for us, since I worked a bit on trying to combine the resources of more than one blade. But man, it just devolved into a giant mess in the end! I think I still have some PTSD from it :P
