By the time my travel to Dallas for SC18 was approved, STEM-Trek’s UbuntuHouse was already full.

When I was looking for accommodations, I was advised to consider places next to the DART light rail service. Because I booked late, and because tens of thousands were in town for the conference, the only place I could find was some distance from the convention center.

On the first day of the conference, the hotel shuttle dropped me at Burbank rail station. I had no Internet access to check for the DART stop that was closest to the convention center. When I tried to buy a ticket, the machine wasn’t working.

When I got news that my SC18 support was approved, I was delighted, but at the same time in the dark about the whole thing as it was my first time to attend a conference of such magnitude.

After registration, I faced the dilemma about which sessions to attend. As I was the only delegate from University of Botswana (UB) to attend this year, I tried by all means to gather as much information as I could for UB researchers, systems administrators and everyone else. As a sysadmin, I was attracted to container computing sessions and attended a number of them, as well as tutorials on Krbenetes and an HPC containers BoF.

For the benefit of our UB  cluster, I went to sessions on MPI & OpenMPI; …

Great news! Top500 announced the student cluster competition teams that will compete during the International Supercomputing Conference (ISC) in Frankfurt, Germany June 16-20, 2019.

While the US didn’t send a team last year, it’s good to know that the U-Mass Green Team will be there!

If you read my two-part series in Top500 about the competition last summer, you may recall me noting that the US was a no-show. In 2012 when the contest was first launched, Germany, and two US teams prevailed. But from 2013 forward, South Africa, two Chinese universities, and Singapore have rallied, with South Africa winning the top honor for three out of the past seven years.

Since many US states and European countries have hosted student cluster competitions longer than others, their absence or failure to place in the top three inspired me to interview team leaders to find out …

I started my day with the “Machine Learning in HPC Environments” workshop. The workshop moderator briefly talked about Alan Turing’s proposal of intelligent computers and how the term “machine learning” was coined in reference to teaching a computer to play games. ML developers still work hard to game computers good at games, but the moderator named some important changes that have occurred in the field. He pointed to better algorithms, big data, and more computing power as the primary culprits for the dramatic improvement in machine learning software in recent years. After all these huge advances, how will machine learning be able to progress even further? By the end of the workshop, I was convinced that the answer is training parallelization.

The first keynote talk was by Dr. Azalia Mirhoseini from Google Brain. She discussed a novel architecture for deep neural networks …

The Centre for High Performance Computing (CHPC) South Africa has won the Workforce Diversity Leadership Award following votes by readers of HPCWire, a leading high performance computing online publication.

The centre won the award for leading the re-purposing and re-deployment of high performance computing systems in Africa, a project done in collaboration with Texas Advanced Computing Centre, Cambridge University, Dell as well as the Departments of Science and Technology and of International Relations and Cooperation of South Africa.

The project’s aim is for these retired systems to be re-used for training purposes and well as for academic research in research councils and in universities.

The first activity began at 7:15 am in a ballroom for a mentoring breakfast. It was fun to start the day in an altruistic way. Although I was still tired from the previous days’ activities, it was refreshing to talk with more students.

After the keynote, we all made our way into the exhibit hall. I had plans to connect with colleagues at their booths and to meet a few others who were recommended to me. Finding my way through the booths and bumping into people I know was an interesting situation. I never thought that I would “know” so many people at such a large conference. Eventually, I found my way to …

Today I am involved in the Early Career program. I’m looking forward to meeting people who haven’t been at their jobs for very long. The day begins with an introduction and activity based on our Clifton Strengths assessment results. After meeting some of the participants of the program, we begin a new activity. We break into groups of 4-5 people and form a fake company. We assign roles based on people’s strengths. For example, Latifa was chosen as our CEO because she is organized and can “Woo” others. We feel she will be effective at accomplishing her vision. I decide that my strengths are well-suited for a Marketing and Communications Director position. I’m very …

After getting through the registration line, I headed down the long hallway toward my first SC19 Workshop. I was distracted by familiar voices and faces, which made it difficult to continue toward the room to make it on time.

I found a seat and reviewed the schedule. The keynote speaker would kick it off with a talk about using HPC to recover lost histories of black women. After discussing the details about the goals of the project and how the research team chose search terms to produce key documents that would make up the projects corpus, the speaker made a few comments about the concept that writing is a privilege. I was taking notes to prepare …

SC is

SC is innovation… from new ideas to products, from concepts to prototypes, from technology to society.

SC is collaboration… from a node to a supercomputer, from a researcher to a consortium, from people to communities.

SC is communication… from inter-node to intra-node, from conversations to keynotes, from gathers to scatters.

SC is inspiring… from new minds to experts, from human brains to artificial intelligence, from passion to innovation.

SC is science… from observations to questions, from hypotheses to experiments, from data to conclusions, from conclusions to SC publications.

SC is networking… from students to advisors, from business to friendship, from partners to competitors.

SC is empowering… from majorities to minorities, from students to directors, from genders to ethnicities.

SC is fun… …
