How to Write a Makefile with Ease

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 as follows. The command will compile each C++ source file and…

C++ Logging Module Designed for Research : 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 help to reduce developing and debugging time significantly. Why Not…

Why Researchers Should Use C++ Unit Testing

In this post, I will explain how to use GTest (Google C++ Testing Framework) configured with CMake to handle C++ unit testing. Unit testing ensures you the correctness of your code especially when you modify it to incorporate optimizations / special conditions. Purpose Statement Often in academia and research, people tend to think that investing…

Hacking DNN Architectures in Cloud Environments

Deep Neural Networks (DNN) are increasingly being deployed in commercial cloud environments. However, in shared environments your intellectual property might not be safe as you once thought. In fact, you might just have allowed your competitor to reverse engineer your architecture. In this post, I will explain how an adversary can use the cache hierarchy…

Building an AM Frequency Morse Code Transmitter

This is one of the posts to which I could not assign a category on my website due to the fact that I’ve sticked to posting application layer posts and all other posts are categorized as personal. Recently, I was a teaching assistant for Fundamentals of Electronics which had around 70 students. The course covered…

Globus: An ESB for Supercomputers

Recently, a system administrator complained to me about an issue with Globus: a platform used by the academia to transfer research data efficiently, securely and reliably. Globus is not an online storage but it acts as a mediator between storage systems. Neverthless, Globus seems to solve a widespread problem in academia. Enterprise Service Buses (ESB)…

IWOCL 19: Let’s Teach are Computers to Program

Recently I had the privilege of joining the organizing committee of International Workshop on OpenCL (IWOCL) 2019, as a volunteer. The workshop was three days; However, I was excited to attend a conference held in conjunction with IWOCL which was DHPCC++ (Distributed & Heterogeneous Programming in C/C++). IWOCL: The Push Towards Heterogeneous Programming The end…

Compilation and Linking Cuda with C

Managing complexity and modularity becomes important as your project scope increases. Therefore, separate compilation and linking Cuda with C is a must have. Learn how you could compile your Cuda code separately and link with your C object code. Example Files As an example, we will look at a stencil computation (nearest neighbor computation). Let’s…

Roll a Dice on a Quantum Computer

When I say “Roll a Dice on a Quantum Computer”, technically there is no dice and it’s not entirely a click bait. I’m going to simulate and verify the probability of an 8 sided fair dice. Why would I want to waste resources to do such a simple task. Well, a simple answer. There is…
