Continued from previous article.

In the previous, we studied with VGG16, but this time we will use ResNet for the model.

Introduction

About a month ago, I wrote an article about building a GPU cluster using kubernetes in this article. At that time, the GPU pod was in Pending state and did not work. After that, I managed to get it to work thanks to the advice of a certain person, so I’ll summarize it here.

In my environment, there is a problem that the GPU pod does not start up until a certain node is started, and furthermore, I have not been able to specify GPUs in a node, specify nodes, and so on, which is what I assumed, so I decided to call it “the first step”.

Motivation

Immediately after installing Ubuntu, the display resolution was set to 1368x768. The screen was inconveniently small when working with multiple terminals open, and since I had connected to a display (JAPANNEXT JN-MD-IPS1562FHDR) that can display 1920x1080, I wanted to display it in that resolution.

I tried to change the resolution, but got into a bit of trouble, so here is a summary of the process.

Sources

1. Ubuntuディスプレイ解像度の変更|1920x1080 Reading this information, it seems that it is easy to change the resolution using the xrandr command, and it only takes a few minutes of work. I thought it would only take a few minutes to change the display resolution, so I started to work on it.
2. 4.3 Permanently adding undetected resolutions This is the page I referred to when editing xorg.conf.
3. External Monitor, can’t set desired resolution *This page solved the problem. I tried many things without success, and after searching the net further, I finally found an article about the same phenomenon I was experiencing.
4. edid-generator Github page referenced from the above page.
5. 19 xrandr BadMatch Why xrandr is a BadMatch.
6. 4.2.1 EDID checksum is invalid An article about EDID related to the above.
7. Archive:Creating and using edid.bin via xorg.conf An article about edid.bin from xorg. conf to use edid.bin via xorg.conf.

Setup

Normal way

To change the resolution of the display, go to “Settings” -> “Display” and specify the resolution, but in my environment, there is no 1920x1080 entry in this list!

Motivation

I took on the challenge of creating a GPU cluster using multiple workstations I have set up at home to study Kubernetes.

It was a hurdle for me, as I was new to Kubernetes. This is because I had to learn from the documentation whether the operations were necessary only during installation or when building the cluster (during operation).

As it stands, the GPU cluster is not operational!　This document is incomplete.

Motivation

I had been thinking of the place to compile and store some researches and trials I had done on my field of interest. I decided to use mark downs to describe them, because I’d like to be able to rerecence pages on the internet, display source files such as shell script, and even express formulas.

When I was thinking about it, GigHub comes to mind and I decided to store and publish it on GitHub Pages.
