"I am captivated by how far HPC will unleash the power of computational intelligence."
"SPQR - So many Problems running QuantumespResso"
"I'd like to upgrade from a 4.3-bit to a 64-bit computer."
"hpc computer go brrr"
"Without the wind, the grass does not move. Without software hardware is useless."
"HPC: Because waiting for a regular computer is like watching paint dry."
"HPC is really fascinating"
"Have you tried restarting the PC?"
"I needed a new computer, so I tried HPC"
"I strive to improve life through HPC."
"I joined RACKlette because ETH didn't stress me enough."
"Truth hides in computation."
"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.
"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.
"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.
"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.
"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.
"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.
"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.
"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.
"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.
"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.
"I am keen to tackle real-world problems using HPC"
"Imagine going from lifting 8kg at the gym to 512kg... that's how I feel about working with Emmi!"
"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.
"When Moore's law is dying, you simply have to add more nodes."
Wendelin was a team member in 2022 and attended SC22.
Our team scored 3rd place overall and we are especially proud of receiving the award for the best HPL benchmark score. In fact, our HPL score was the highest ever achieved in the history of the Student Cluster Competitions!
Emmentaler Mark III
Our third iteration of Emmentaler (short: Emmi) with drastic vendor changes and even more GPUs
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.
The team has participated in the virtual competition of the SC20 conference running on Microsoft Cyclecloud infrastructure. The team placed 5th overall.
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.
Emmentaler Mark II
Our second iteration of Emmentaler (short: Emmi) with minor upgrades for even more performance
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.
Our team has placed 5th overall in the highly competitive setup of the competition at Supercomputing in Denver. The team scored 3rd on benchmarking.

In honor of the delicious Swiss cheese we named our team's first Cluster "Emmentaler"
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.
We are proud of having placed 3rd overall at ISC19 SCC and additionally won the special award for the highest Linpack run.
