Knight’s Landing at SC13 and Leveraged SCDOs

Andy Patrizio, IT World, Intel changes the whole supercomputing game with Knight’s Landing, here.

Much more important is what else it takes away. Knight’s Landing will erasing the memory buffer and PCI Express bus that sat between the CPU and main memory and the coprocessor chip and frame buffer memory in the Xeon Phi card. Now that applications run entirely natively instead of offloading the data sets to the coprocessor, all of that latency goes away.

Now you will have both scalar processor cores and vector processor cores on the same chip sharing access to unified memory. This is huge. A fair amount of time has to go into offloading data sets from main memory to the frame buffer memory of the co-processor and then back to the CPU and main memory. It’s why Nvidia had to come out with the CUDA language, because plain old C++ or Java wouldn’t work.

Matt Levine, Bloomberg, Welcome Back, Leveraged Super Senior Synthetic CDOs, here.

You can tell that leveraged super senior synthetic collateralized debt obligation tranches are fun because they are called leveraged super senior synthetic collateralized debt obligation tranches, and anything with that many words in its name is up to something. And in fact LSS CDOs were popular prior to the financial crisis, got various people in various kinds of trouble, and more or less vanished.

But now Euromoney is reporting that Citigroup is trying to market them again, with a slight modification that might get people into less or at least different kinds of trouble, though it is far from clear that anyone will be interested.
