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
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
C++ Concepts: A World Without Unchecked Generics
C++ concepts is a revolutionary idea aimed at building better and safer abstractions at the code level. Generics in C++ allows to express an abstract operation (maybe an algorithm) to different types (classes). Templates allowed abstraction of operations such as sort which can be used to sort a vector, an array or any object with … Continue reading C++ Concepts: A World Without Unchecked Generics
How to Write a Makefile with Ease
[wpdiscuz-feedback id="jd04i5a51j" question="New Feature: Inline Commenting! Please leave your thoughts." opened="0"][/wpdiscuz-feedback] Makefiles provide a way to organize build steps involved in C / C++ project compilation. This article explains how you can set up your own makefile for your C / C++ project. Why Use a Makefile? Usual compilation with g++ will involve a command … Continue reading How to Write a Makefile with Ease
C++ Logging Module Designed for Research : rlog
screenshot shows a demonstration of the logs generated through rlog CHECK OUT ON GITHUB Why Should Researchers use C++ Logging? Most research and development occur in a haphazard manner and not investing time early on to adopt good development practices can increase the difficulty in extending research projects. Having a good C++ logging framework can … Continue reading C++ Logging Module Designed for Research : rlog
