During early summer 2020, we benchmarked recent GPU models available on Nef cluster for deep-learning using ResNet-50 model training, with ImageNet 2021 dataset and TensorFlow 2.0 official implementation. Please find here a summary of the results and lessons learnt. The different Nvidia GPU models tested are : GTX1080Ti a GeForce…
Here are this month articles: Hydra A fresh look at configuration for machine learning projects Hydra is a recently released open-source Python framework developed at Facebook AI that simplifies the development of research and other complex applications. Great when you want to launch the same code with different options: python…
With the advent of the Qt Installer FrameWork (QtIFW), it has never been easier to provide installers for your Qt based applications. Such installers can be either online (i.e. they fetch contents from the internet from repositories during the installation process, thus allowing updates), or offline (i.e. all the contents…
The nef cluster comes with 6 nodes equipped with Nvidia GPUs. Typically, they are used with cuda or opencl to run some highly parallel computations. But you may also run OpenGL applications on them.
Ever wanted to monitor the filesystem changes ? Since Linux 2.6.25, the kernel provides us with a signal driven I/O notification API and the inotify-tools RPM provides a set of tools to interact with the kernel. inotify in action: a simple way to test this API is to run the…
Qt provide a standard mechanism (aboutToQuit() signal) to insure that a callback is executed at the end of the QApplication event loop. This is typically used to add some cleanup code to your application. Infortunately, Qt does not provide a “aboutToRun()” if you want to execute an initializing code just…
If you ever wanted to replace some symbol in a library, in order to inspect what happens in a binary you don’t have the source code or even to inject some code, this can be done using the LD_PRELOAD trick. To use it, invoke your binary as such: $ LD_PRELOAD=somelib.so…
CMUSphinx, where CMU stands for Carnegie Mellon University, is an open source toolkit for speech recognition. This proof of concept, aims at using speech instead of a mouse to trigger transitions within a state machine, and have a visual feedback of it.
