Please note that Hebbe will be retired from SNIC use at the end of 2020!
Please note that Hebbe will be decommissioned at the end of 2020, active project will most likely be moved to another SNIC resource at that time.
The Hebbe cluster is built on Intel Xeon E5-2650v3 (code-named "haswell") CPU's.
The system has a total of 323 compute nodes (total of 6480 cores) with 27 TiB of RAM and 6 GPUs. More specific:
260 x 64 GB of RAM (249 of these available for SNIC users)
46 x 128 GB of RAM (31 of these available for SNIC users)
7 x 256 GB of RAM (not available for SNIC users)
3 x 512 GB of RAM (1 of these available for SNIC users)
1 x 1024 GB of RAM
4 x 64 GB of RAM and NVIDIA Tesla K40 GPU (2 of these available for SNIC users)
2 x 256 GB of RAM and NVIDIA k4200 for remote graphics
Each node have 2 CPUs with 10 cores each.
There's a 10Gigabit Ethernet network used for logins, and a dedicated management network and an Infiniband high-speed/low-latency network for parallel computations and filesystem access. The nodes are equipped with Mellanox ConnectX-3 FDR Infiniband 56Gbps HCA's.

Abisko is technically decommissioned, but it's still live and kicking and can be used for the SNIC 2020/5-176 project for a couple of weeks
The cluster has 15744 cores with a peak performance of over 150 Tflops/s. For high parallel performance, the system is equipped with a high bandwidth, low latency QDR InfiniBand interconnect, with full bisectional bandwidth. All nodes have at least 2 GB/core and some nodes have over 8 GB/core. For more information about the system and available software see the HPC2N web-pages.
Applications are normally evaluated during the last week each month.
Tetralith is a general computational resource hosted by NSC at Linköping University.
Tetralith servers have two Intel Xeon Gold 6130 processors, providing 32 cores per server. 1844 of the servers are equipped with 96 GiB of primary memory and 64 servers with 384 GiB. All servers are interconnected with a 100 Gbit/s Intel Omni- Path network which is also used to connect the existing storage. Each server has a local SSD disk for ephemeral storage (approx. 200GiB per thin node, 900GiB per fat node). An IBM Spectrum Scale system comprises the centre storage. 170 of the Tetralith nodes are equipped with one NVIDIA Tesla T4 GPU each as well as a high- performance NVMe SSD scratch disk of 2TB.
Project storage for NAISS as well as LiU Local projects with compute allocations on resources hosted by NSC.
Centre Storage @ NSC is designed for fast access from compute resources at NSC. It consists of one IBM ESS GL6S building block and one IBM ESS 5000 SC4 building block.
In total there are 946 spinning hard disks and a small number of NVRAM devices and SSDs which act as a cache to speed up small writes. The total disk space that is usable for storing files is approximately 6.9 PiB.
