Reverse Engineering DNNs with JIT GEMM Libraries

What is JAXED? JAXED [JIT + AXED] is a security attack targeted reverse engineering DNNs (Deep Neural Network) architectures using JIT optimized GEMM libraries. Hyperparameters specify the model architecture of a DNN. E.g.:- number of layers, number of channels in a filter etc. In our latest work, we exploit a novel side channel exposed during … Continue reading Reverse Engineering DNNs with JIT GEMM Libraries

Runtime Code Generation for Convolutions

marlin-lib

Summary Our work MARLIN (Matrix Multiplication through Reduced Load Instructions), is now available on github. MARLIN is a runtime code generation library for convolution kernels. The paper won the first place in graduate student category in CGO 2021 (International Symposium on Code Generation and Optimization). Here are the links for the 10 minute presentation talk … Continue reading Runtime Code Generation for Convolutions

Assembly Function using AT&T Syntax

In this blog post, I will provide a detailed explanation about writing a C++ program with an external Assembly function written for the X86_64 architecture. There are three types of Assembly syntax in use today: Intel syntax, AT&T syntax and GAS syntax (General Assembly). Although Intel syntax is much easily readable and is widely used … Continue reading Assembly Function using AT&T Syntax

Blocked Matrix Multiplication

Having read this article, you will be able to implement blocked matrix multiplication and also to understand the number of memory accesses encountered in blocked matrix multiplication. In my next article, I will explain how these ideas can be extended to SIMD (Single Instruction Multiple Data) vector instructions. Why is Matrix Multiplication Important? Matrix multiplication … Continue reading Blocked Matrix Multiplication
