Hello world! Xavier

by

Hello there, I’m Aoyagi, a 4th-year undergraduate (B4) student.
As a part of ‘skill map’ training for new B4 students, each person gets one jetson Xavier.

Xavier, Xavier, Xavier♪♪
Have you ever heard Xavier before♪♪
That’s the same spelling as that Xavier♪♪
What a surprise, Xavier♪♪

Although this Xavier, the Nvidia’s missionary, has the almost same size as Rasberry pi, it has a GPU inside.
Xavier is definitely much powerful than its appearance.
After installing the OS, we tried to let it learn the MNIST dataset.
Xavier says, ‘No sweat!’ And his fan was not even rotated.

Okay there. It seems like we have to write some tough programs to make it sweats!

Welcome to Takizawa Lab, Singularity!

by

Hi, I am Furuhata a.k.a “shimo”.
A type of container environment, Singularity, is installed on the Lab’s servers.
(I spent the whole golden week (the long vacation in Japan) for it.)

Singularity is often compared to The “BLUE WHALE”.
The reason our lab chose the Singularity instead of docker is that Singularity can be ran without root permission.
Also, since Singularity is the container designed for HPC, we can actually use it in the supercomputer systems.

I strongly hope that Singularity could enhance labmate’s productivity and manage servers easier.

Hello, this is Liu from Takizawa Lab.

2021 IEEE Symposium on Low-Power and High-Speed Chips and Systems (COOL Chips 24) was held during April 14-16.

Because of the COVID-19, the COOL Chips 24 was held as a virtual conference.

I made a presentation in the Poster Session. Here are the details of the poster.

Farewell party for the year 2020 was held

by

At the end of March, we had a farewell party for the year 2020.
It’s a pity that we couldn’t meet face-to-face for the last time due to the new coronavirus, but it was nice to have a good time with everyone in the lab as usual!
In April, new members will be added to our lab, and we will start our new life at Takizawa Lab.
We wish the seniors all the best in their new positions and the further development of our laboratory!

A scaled-down graduation ceremony was held in our lab

by

Due to the coronavirus, the graduation ceremony of Tohoku University was canceled. Instead, a small one was held in our lab.

Hope all alumni could enjoy their job and study in the future.
Also, don’t forget to come back again and keep communications with our labmates!

One week has passed since the powerful magnitude 7.1 earthquake

by

Hi, there. This is Minglu, who felt really scared for the terrible earthquake even though it is my fifth year in Japan.
Around 13th 11pm, the powerful magnitude 7.1 earthquake jolts Tohoku area.
The next morning, Prof. Takizawa sent some photos of our lab after the earthquake via slack.

(upper photos) In the student room, books were fell off the shelf, monitors were fell off on the top of desks, and drawers were pulled out.
(lower photos) The experiment room was really chaotic. The keyboards were fell off the shelf that keycaps were coming apart, and even the server racks were moved.
It is hard that such a big earthquake happened near the graduation season, especially near the thesis’s deadline.
Fortunately, all of our servers are fine due to the anti-earthquake procedures that there is no data loss.
Take this occasion, I would like to introduce the main anti-earthquake procedures we have done so far.

(upper photos) Firstly, about our students’ room:
– The top two layers of the bookshelf have fall prevention rods that prevent books from falling off and hitting the students’ desks.
– Since the earthquake happened on a Saturday night, no one was in the lab. In case of being in the lab, we placed the helmets near everyone’s desk that students can wear them and run away.
– To prevent the fire, all electrical outlets are organized carefully.
(lower photos) Next is our experiment room.
– All shelves were fixed to the wall by furniture-wall-brackets so that shelves will not fall off to the floor.
– There are many servers in our experiment room. Also, to prevent fire, all outlets are managed carefully by numbering and calculating each current limitation.
– There are lots of equipment such as the USB-cables are stored on the shelf. The top layer of the shelf also has the anti-earthquake strap.
Besides, our lab uses both cloud storage and local NAS to store and manage all research data.
The NAS in our lab has the redundancy that all data could be repaired even one or two HDDs are broken.
The most significant damages by this earthquake are the monitors that were fell off the desk, and a few are broken. To prevent this problem, we plan to buy some anti-earthquake mats for fixing the monitors on each desk.
All in all, it is fortunate that no labmate got injured due to the earthquake.
Though one week has already passed and some aftershocks still come, our daily lives are coming back. Everyone is enjoying their campus lives.
