Setting up a GPU server with scheduling and containers

Our group recently acquired a new server to do some deep learning: a SuperMicro 4029GP-TRT2, stuffed with 8x NVidia RTX 2080 Ti. Though maybe a bit overpowered, with upcoming networks like BigGAN and fully 3D networks, as well as students joining our group, this machine will be used quite a lot in the future.

One challenge is, is how to manage these GPUs. There are many approaches, but given that most PhD candidates aren't sysadmins, these range from 'free-for-all', leading to one person hogging all GPUs for weeks due to a bug in the code, to Excel sheets that noone understands and noone adheres to because changing GPU ids in code is hard. This leads to a lot of frustration, low productivity and under-utilisation of these expensive servers. Another issue is conflicting software versions. TensorFlow and Keras, for example, tend to do breaking API changes every now and then. As t

15-Minute Minecraft Plugin Tutorial For 1.8.8 - 1.20

In this new Minecraft plugin development guide, I'll show you how to make Minecraft plugins for Bukkit, Spigot and Paper.

This guide covers Minecraft plugins for 1.8.8 to 1.20.

We'll be using IntelliJ with a dedicated extension for Minecraft plugin development to make this process fast and easy.

If you're tired of limiting plugins and waiting for developers, if you want to make a truly unique servers customized from the ground up, click here and I'll show you how to do it in 20 days (without experience).
