For Help on MidwayR

General Design

MidwayR is comprised of two login nodes and four compute nodes. The total installed storage on MidwayR is 441TB. It uses Slurm as its workload manger and the software environment module to manage installed software.

Compute Nodes: As of writing this document, MidwayR hosts four compute nodes with the following specifications:

  • CPUs: Two Intel Xeon Gold 6148 per node
  • CPU code name: Skylake
  • Processor Base Frequency: 2.4GHz
  • Maximum Turbo Frequency: 3.7 GHz
  • Number of cores per processor: 20 cores
  • Total number of cores per node: 40 cores
  • Cache: 27.5 MB L3
  • Memory: 96GB of TruDDR4 2666 MHz RDIMM memory
  • ECC Memory supported

Login Nodes: MidwayR hosts two login nodes: sde-login1 and sde-login2 with the following specifications:

  • CPUs: Two Intel Xeon Gold 6130 per node
  • CPU code name: Skylake
  • Processor Base Frequency: 2.1GHz
  • Maximum Turbo Frequency: 3.7 GHz
  • Number of cores per processor: 16 cores
  • Total number of cores per node: 32 cores
  • Cache: 22 MB L3
  • Memory: 96GB of TruDDR4 2666 MHz RDIMM memory
  • ECC Memory supported

Network:

  • MidwayR uses the Mellanox EDR Infiniband network to tightly connect all the compute nodes and storage. Some of the key features are
    • provide up to 100Gb/s full bi-directional bandwidth per port
    • built with Mellanox’s latest Switch-IB Infiniband switch device
    • Ultra low latency
    • Adaptive routing
    • Port mirroring
    • Congestion control
    • Quality of Service enforcement
  • MidwayR is also outfitted with an 10Gbps Intel Ethernet Adapter

Storage

  • MidwayR mounts two GPFS filesystems that are shared across all nodes: /home and /project.
  • Total storage for /home is 21TB
  • Total storage for /project is 420TB. /home has a strict quota of 30GB. Large data should be placed on /project.
  • The storage is InfiniBand connected
  • The compute nodes have access to the MidwayR /project storage space
  • MidwayR does not have a scratch filesystem.

Operating System

MidwayR runs the CentOS 7 linux operating system designed and tuned to also run large and complex applications. CentOS is a robust open source operating system that offers a manageable platform suited for a wide variety of deployments.

MidwayR use Simple Linux Utility for Resource Management or Slurm as the job scheduler. The Slurm Workload Manager is a an open source job scheduler used by many of the world’s supercomputers and High Performance Computing clusters. Slurm commands enable you to submit, manage, monitor, and control your jobs running on MidwayR.

Essay typer free online composing does not need to be hard. First, you desire to understand the goal of creating essays about yourself. Otherwise, the author may deliver a personal composition that won’t reflect on your own style.
Among the most popular issues for essay about myself is my favourite area essay. There are several things I need to write about in this type of short composition. If you need to purchase article, you should just finish the order form and we’ll assign an article author who’ll write the employment of finest quality for you personally. What details you determine to contain are dependant on the focus of your own composition.
To date I wrote a large variety of essays that you may study.

Software

  • Organized in modules
  • Use module avail, to see the software available on MidwayR
  • To load a particular available package, for example, to load the gcc compiler version 8.2.0, do: module load gcc/8.2.0
  • If you do not specify a version of the package, the default one is loaded
  • To see what environmental variables are modified when for example gcc/8.2.0 is loaded, do:  module show gcc/8.2.0
  • To unload a software: eg.: to unload gcc/8.2.0, do:  module unload gcc/8.2.0

Security and Reliability

The following security and reliability features are currently supported on the processors on MidwayR

  • Intel AES New instructionsIntel® AES New Instructions (Intel® AES-NI) are a set of instructions that enable fast and secure data encryption and decryption. AES-NI are valuable for a wide range of cryptographic applications, for example: applications that perform bulk encryption/decryption, authentication, random number generation, and authenticated encryption.
  • Intel Trusted Execution Technology: Intel® Trusted Execution Technology for safer computing is a versatile set of hardware extensions to Intel® processors and chipsets that enhance the digital office platform with security capabilities such as measured launch and protected execution. It enables an environment where applications can run within their own space, protected from all other software on the system.
  • Execute Disable Bit: Execute Disable Bit is a hardware-based security feature that can reduce exposure to viruses and malicious-code attacks and prevent harmful software from executing and propagating on the server or network.
  • Intel Run Sure TechnologyIntel® Run Sure Technology, includes advanced RAS (reliability, availability and serviceability) features that deliver high reliability and platform resiliency, to maximize uptime of servers running mission-critical workloads.
  • Mode-based Execute Control (MBE): Mode-based Execute Control can more reliably verify and enforce the integrity of kernel level code.
