+# Hardware Overview
+
+The Anselm cluster consists of 209 computational nodes named cn[1-209] of which 180 are regular compute nodes, 23 are GPU Kepler K20 accelerated nodes, 4 are MIC Xeon Phi 5110P accelerated nodes, and 2 are fat nodes. Each node is a powerful x86-64 computer, equipped with 16 cores (two eight-core Intel Sandy Bridge processors), at least 64 GB of RAM, and a local hard drive. User access to the Anselm cluster is provided by two login nodes login[1,2]. The nodes are interlinked through high speed InfiniBand and Ethernet networks. All nodes share a 320 TB /home disk for storage of user files. The 146 TB shared /scratch storage is available for scratch data.
+
+The Fat nodes are equipped with a large amount (512 GB) of memory. Virtualization infrastructure provides resources to run long-term servers and services in virtual mode. Fat nodes and virtual servers may access 45 TB of dedicated block storage. Accelerated nodes, fat nodes, and virtualization infrastructure are available [upon request][a] from a PI.

+
+The cluster compute nodes cn[1-207] are organized within 13 chassis.
+
+There are four types of compute nodes:
+
+* 180 compute nodes without an accelerator
+* 23 compute nodes with a GPU accelerator - an NVIDIA Tesla Kepler K20m
+* 4 compute nodes with a MIC accelerator - an Intel Xeon Phi 5110P
+* 2 fat nodes - equipped with 512 GB of RAM and two 100 GB SSD drives
+
+[More about Compute nodes][1].
+
+GPU and accelerated nodes are available upon request, see the [Resources Allocation Policy][2].
+
+All of these nodes are interconnected through fast InfiniBand and Ethernet networks.  [More about the Network][3].
+Every chassis provides an InfiniBand switch, marked **isw**, connecting all nodes in the chassis, as well as connecting the chassis to the upper level switches.
+
+All of the nodes share a 360 TB /home disk for storage of user files. The 146 TB shared /scratch storage is available for scratch data. These file systems are provided by the Lustre parallel file system. There is also local disk storage available on all compute nodes in /lscratch.  [More about Storage][4].
+
+User access to the Anselm cluster is provided by two login nodes login1, login2, and data mover node dm1. [More about accessing the cluster][5].

+# Introduction
+
+Welcome to the Anselm supercomputer cluster. The Anselm cluster consists of 209 compute nodes, totaling 3344 compute cores with 15 TB RAM, giving over 94 TFLOP/s theoretical peak performance. Each node is a powerful x86-64 computer, equipped with 16 cores, at least 64 GB of RAM, and a 500 GB hard disk drive. Nodes are interconnected through a fully non-blocking fat-tree InfiniBand network and are equipped with Intel Sandy Bridge processors. A few nodes are also equipped with NVIDIA Kepler GPU or Intel Xeon Phi MIC accelerators. Read more in [Hardware Overview][1].
+
+Anselm runs with an operating system compatible with the Red Hat [Linux family][a]. We have installed a wide range of software packages targeted at different scientific domains. These packages are accessible via the [modules environment][2].
+
+The user data shared file-system (HOME, 320 TB) and job data shared file-system (SCRATCH, 146 TB) are available to users.
+
+The PBS Professional workload manager provides [computing resources allocations and job execution][3].

docs.it4i/anselm/network.md

+# Network
+
+All of the compute and login nodes of Anselm are interconnected through an [InfiniBand][a] QDR network and a Gigabit [Ethernet][b] network. Both networks may be used to transfer user data.
+
+## InfiniBand Network
+
+All of the compute and login nodes of Anselm are interconnected through a high-bandwidth, low-latency [InfiniBand][a] QDR network (IB 4 x QDR, 40 Gbps). The network topology is a fully non-blocking fat-tree.
+
+The compute nodes may be accessed via the InfiniBand network using the ib0 network interface, in address range 10.2.1.1-209. The MPI may be used to establish native InfiniBand connection among the nodes.
+
+!!! note
+    The network provides **2170 MB/s** transfer rates via the TCP connection (single stream) and up to **3600 MB/s** via the native InfiniBand protocol.
+
+The Fat tree topology ensures that peak transfer rates are achieved between any two nodes, independent of network traffic exchanged among other nodes concurrently.
+
+## Ethernet Network
+
+The compute nodes may be accessed via the regular Gigabit Ethernet network interface eth0, in the address range 10.1.1.1-209, or by using aliases cn1-cn209. The network provides **114 MB/s** transfer rates via the TCP connection.
+
+## Example
+
+In this example, we access the node cn110 through the InfiniBand network via the ib0 interface, then from cn110 to cn108 through the Ethernet network.
+
+```console
+$ qsub -q qexp -l select=4:ncpus=16 -N Name0 ./myjob
+$ qstat -n -u username
+                                                            Req'd Req'd   Elap

+# Introduction
+
+This section contains documentation of decommissioned IT4Innovations' supercomputers and services.
+
+## Salomon
+
+The second supercomputer, built by SGI (now Hewlett Packard Enterprise), was launched in 2015. With a performance of 2 PFlop/s, it was immediately included in the TOP500 list, which ranks the world's most powerful supercomputers. It stayed there until November 2020, falling from the 40th place to 460th.
+
+Salomon was decommissioned after six years - at the end of 2021.
+

+
+## Anselm
+
+The first supercomputer, built by Atos, was launched in 2013. For the first 3 years, it was placed in makeshift containers on the campus of VSB – Technical University of Ostrava, and was subsequently moved to the data room of the newly constructed IT4Innovations building. Anselm's computational resources were available to Czech and foreign students and scientists in fields such as material sciences, computational chemistry, biosciences, and engineering.
+
+At the end of January 2021, after more than seven years, its operation permanently ceased. In the future, it will be a part of the [World of Civilization exhibition][a] in Lower Vitkovice.

+# Hardware Overview
+
+The Barbora cluster consists of 201 computational nodes named **cn[001-201]**
+of which 192 are regular compute nodes, 8 are GPU Tesla V100 accelerated nodes and 1 is a fat node.
+Each node is a powerful x86-64 computer, equipped with 36/24/128 cores
+(18-core Intel Cascade Lake 6240 / 12-core Intel Skylake Gold 6126 / 16-core Intel Skylake 8153), at least 192 GB of RAM.
+User access to the Barbora cluster is provided by two login nodes **login[1,2]**.
+The nodes are interlinked through high speed InfiniBand and Ethernet networks.
+
+The fat node is equipped with 6144 GB of memory.
+Virtualization infrastructure provides resources for running long-term servers and services in virtual mode.
+The Accelerated nodes, fat node, and virtualization infrastructure are available [upon request][a] from a PI.
+
+**There are three types of compute nodes:**
+
+* 192 compute nodes without an accelerator
+* 8 compute nodes with a GPU accelerator - 4x NVIDIA Tesla V100-SXM2
+* 1 fat node - equipped with 6144 GB of RAM
+
+[More about compute nodes][1].
+
+GPU and accelerated nodes are available upon request, see the [Resources Allocation Policy][2].
+
+All of these nodes are interconnected through fast InfiniBand and Ethernet networks.
+[More about the computing network][3].
+Every chassis provides an InfiniBand switch, marked **isw**, connecting all nodes in the chassis,
+as well as connecting the chassis to the upper level switches.
+
+User access to Barbora is provided by two login nodes: login1 and login2.
+[More about accessing the cluster][5].
