JMP Data Types & Graphs


Variables are either Continuous or Categorical (Nominal or Ordinal).
Continuous (Y) v/s Continuous (X) --> BIVARIATE
Continuous (Y) v/s Categorical (X) --> ONE WAY ANOVA

Categorical(Y) v/s Categorical (X) --> CONTINGENCY
Categorical (Y) v/s Continuous (X) --> LOGISTIC

HPC & CoProcessors


Traditionally, HPC environment -> Co Processors or Accelerators (non bootable) combined with server x86 processors, to offload tasks, interfacing through PCIe, typically GPU class SoC's since these provide high bandwidth performance. GPU SoC need GDDR5, server processors will need their own memory (DDR4),this increases system complexity and power consumption. Although this approach is good for certain applications, in other cases, especially with a large mix of single-threaded, serial & serial/parallel mixed applications, this has severe limitations. NVidia Tesla (K40) & Intel Knights Corner are examples of this implementation. Intel's Knights Landing is a paradigm shift in HPC, since it eliminates the need for a coprocessor. This is a fully bootable x86 server/accelerator fused with high capacity DDR4 controllers as a single SoC packaged as an MCM with 8 stacks of HMC (multi channel DRAM with upto 16GB memory). This reduces system complexity and improves system efficiency.
