Past Members
Manuel Burger
I love the idea of performance and making things go fast.
Manuel was a founding member of the team, taking part at ISC19, SC19, and ISC20.
The team could always rely on his expert skills - there is no compiler error Manuel could not debug. His relentless research into the best matrix configuration helped RACKlette win the "Highest LinPACK" award at ISC19.
He also designed the original RACKlette logo.
Jinfan Chen
Here is our Asian team member with an affinity for complex math problems.
Jinfan has been part of the team in the preparations for SC19 and during the competition at ISC20.
Thore Goebel
Running systems and marathons
Thore was a founding member of the the team and took part in the competitions at ISC19 Frankfurt and SC19 Denver. Amongst many other things the team was always able to rely on his great scripting skills.
André Graubner
I enjoy tackling seemingly simple problems that even the largest computers still struggle with.
André was a founding member of the team, and competed at ISC19. He has been essential to the extensive optimisations on the machine learning models at ISC19, which was key to the team securing 3rd place overall.
Emir Isman
It is always fascinating to see the impact of computing in every field of our lives.
Emir has competed with RACKlette at SC19, ISC20 and SC20. His profound knowledge and experience with Linux and cloud systems have always been of great value to the team.
Simon Jacob
Being efficient is just being lazy, but in a clever way.
Simon has been part of the team during the competitions at SC19, ISC20 and SC20 and has contributed with his knowledge about Linux systems.
Valeria Jannelli
Being a passionate violinist, I am particularly interested in how HPC can revolutionize music.
Valeria was a founding member of the team. She has been part of the team during the competitions at ISC19 in Frankfurt, Germany and SC19 in Denver, Colorado US.
Lukas Kapp-Schwoerer
I am passionate about finding efficient solutions to complex computational problems
Lukas was a founding member of the team, and competed at ISC19. Without him, RACKlette would not exist today. He has been essential to the extensive optimisations on the machine learning models at ISC19, which was key to the team securing 3rd place overall.
Ege Karaismailoglu
I’m fascinated by concepts and solutions built on fundamental relations between seemingly unrelated fields.
Ege was a founding member of the team. He has been essential to the extensive optimisations on the machine learning models for ISC19 in Frankfurt, which has been a key to the team's success there.
Jan Kleine
I’m building an 8-Bit computer on breadboards.
Jan was a founding member of the team, taking part at ISC19, SC19, ISC20, and SC20.
With his deep knowledge of our hardware and software setup he always kept a clear head during stressful competition situations. He was indispensable at tutoring new team members and bringing them up to speed working with the cluster.
Rahul Steiger
I am keen to tackle real-world problems using HPC
Antonia Unger
Imagine going from lifting 8kg at the gym to 512kg... that's how I feel about working with Emmi!
Simon Wachter
I like to apply concepts from lectures to real-world applications.
Simon has been a member of the team during the virtual competition at SC20.
Wendelin Wemhöner
When Moore's law is dying, you simply have to add more nodes.
Wendelin was a team member in 2022 and attended SC22.

Emmentaler Mark III
Our third iteration of Emmentaler (short: Emmi) with drastic vendor changes and even more GPUs
Hardware
Following a recent trend and to satisfy our thirst for cores and flops we made some drastic changes to our cluster setup. We are still using 4 nodes, but everything else has changed.
We switched from Intel to AMD and are using their highest-end 64 core processors the AMD EPYC 7742. Each node is equipped with two of these poweful processors for a total of 512 CPU cores in the cluster. To accompany these 512 cores we threw in 512GB of memory on each node and 4 Nvidia V100 GPU accelerators for a total of 2TB of memory and 16 GPUs with 32GB of VRAM each. All of this is connected with a speedy interconnect from Mellanox, namely HDR ConnectX-6 adapters for a 200 Gbit/s connection between our nodes.
SC20 (virtual)
The team has participated in the virtual competition of the SC20 conference running on Microsoft Cyclecloud infrastructure. The team placed 5th overall.
ISC20 (virtual)
The team has participated in the virtual competition of the ISC20 conference running on hardware of the Singapore National Supercomputing Centre (NSCC). Most notable achievement was the teams second place in the machine learning task.
SC19 Denver
Emmentaler Mark II
Our second iteration of Emmentaler (short: Emmi) with minor upgrades for even more performance
Hardware
Our cluster at SC19 was an iteration over the setup used at ISC19. We kept the 4 node configuration and our 8180 Xeon Platinum CPUs for a total of 224 cores in the system. The nodes were still connected by a Mellanox Infiniband EDR 100Gbit/s switch and our head node ran the Bright Cluster Management system software. We upgraded to 12 V100 Tesla accelerators (3 nodes with 4 each) and added 16 Intel Optane SSD drives to build a fast parallel file system.
Ranking
Our team has placed 5th overall in the highly competitive setup of the competition at Supercomputing in Denver. The team scored 3rd on benchmarking.

Emmentaler
In honor of the delicious Swiss cheese we named our team's first Cluster "Emmentaler"
Hardware
Our cluster at ISC19 was a 4 node system. Each node contained two Intel Xeon 8180 Platinum CPUs. Two nodes were additionally equipped with 4 Nvidia Tesla V100 GPU accelerators. The nodes were connected with an Infiniband EDR 100Gbit/s Interconnect from Mellanox through a switch. Node 0 has been used as a head node and ran the Bright Cluster Management software.
Ranking
We are proud of having placed 3rd overall at ISC19 SCC and additionally won the special award for the highest Linpack run.
