Compiling GCC-10.4.0 on CentOS-7

Step 1: Download the TarBall version of GCC version. If you want to take look at all the available versions, you can take a look at http://ftp.mirrorservice.org/sites/sourceware.org/pub/gcc/releases/

For this blog entry, we will install GCC-10.4.0. First thing first, let’s get the Tarball

% wget http://ftp.mirrorservice.org/sites/sourceware.org/pub/gcc/releases/gcc-10.4.0/gcc-10.4.0.tar.gz

Step 2: Make sure the bzip2 is available in the System

% yum install bzip2 bzip2-devel

Step 3: Untar the TarBall 

% tar -zxvf gcc-10.4.0.tar.gz
% cd gcc-10.4.0

Step 4: Download the prerequisites and start configuring the GCC

% ./contrib/download_prerequisites
% ./configure --prefix=/usr/local/gcc-10.4.0 --disable-multilib --enable-languages=all
% make -j 8
% make install

Step 5: Verify the Installation

% gcc --version

Compiling VASP.6.3.0 with GPGPU Capability using Nvidia HPC-SDK on Rocky Linux 8.5

To Compile VASP with GPGPU Capability using Nvidia HPC-SDK. For more information, do take a look at VASP – Install VASP.6.X.X

VASP support several compilers. But we will be focusing on Nvidia HPC-SDK only for this blog. To download the NVIDIA HPC-SDK

To compile Nvidia HPC SDK, do take a look at HPC SDK Documentation

% tar -xpfz <tarfile>.tar.gz

You may want to use modulefiles provided at hpc-sdk if you are using Module Environment

% module use /usr/local/nvidia/hpc_sdk/modulefiles

You should be able to see something like

------------------- /usr/local/nvidia/hpc_sdk/modulefiles ---------------
nvhpc-byo-compiler/22.5  nvhpc-nompi/22.5  nvhpc/22.5

You can untar the VASP.6.3.3. and potpaw_PBE.54

% tar -xvf vasp.6.3.0.tar
% tar -xvf potpaw_PBE.54.tar

At the installation base of vasp.6.3.0 base

% cp arch/makefile.include.nvhpc_ompi_mkl_omp_acc ./makefile.include

Load the Nvidia GPGPU SDK and compile. If you are using OneAPI Intel Compilers, you can use module use after compilation. It will not be covered in this write-up.

% module use /usr/local/intel/oneapi-2022/modulefiles
% module load nvhpc/22.5
% module load mkl/latest
% make veryclean
% make DEPS=1 -j

If during the make, you encounter the error

/usr/local/nvidia/hpc_sdk/Linux_x86_64/22.5/comm_libs/openmpi/openmpi-3.1.5/bin/.bin/mpif90: error while loading shared libraries: libatomic.so.1: cannot open shared object file: No such file or directory

You can dnf install libatomic

% dnf install libatomic -y

Try Compiling again

Changes to SSH Server on DevCloud

When connecting to the DevCloud for oneAPI

$ ssh devcloud @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that a host key has just been changed. The fingerprint for the ED25519 key sent by the remote host is SHA256:/Dlip01tdMyRmhMDc870Z4Uk7AancwwoTnbb0EZajK0. Please contact your system administrator. Add correct host key in /home/<user_name>/.ssh/known_hosts to get rid of this message. Offending ECDSA key in /home/<user_name>/.ssh/known_hosts:# Host key for ssh.devcloud.intel.com has changed and you have requested strict checking. Host key verification failed. kex_exchange_identification: Connection closed by remote host Connection closed by UNKNOWN port 65535

Cause:

DevCloud have just migrated oneAPI DevCloud to a new SSH tunnel server and upgraded the SSH server version to OpenSSH _8.2p1. For this reason the DevCloud are unable to reuse the old SSH fingerprint for the new server.

Remediation:

Step 1: Remove the Offending FingerPrint(s)

Method 1: rename your existing ~/.ssh/known_hosts file to something else, such as ~/.ssh/known_hosts.yymmdd

$ mv ~/.ssh/known_hosts ~/.ssh/known_hosts.220623

Method 2: remove the offending host SSH fingerprint only:

$ ssh-keygen -R ssh.devcloud.intel.com # Host ssh.devcloud.intel.com found: line 1 # Host ssh.devcloud.intel.com found: line 2 # Host ssh.devcloud.intel.com found: line 3 /home/<user_name>/.ssh/known_hosts updated. Original contents retained as /home/<user_name>/.ssh/known_hosts.old

Step 2: reconnect to the DevCloud and accept the new key.

$ ssh devcloud The authenticity of host 'ssh.devcloud.intel.com (12.229.61.118)' can't be established. ED25519 key fingerprint is SHA256:/Dlip01tdMyRmhMDc870Z4Uk7AancwwoTnbb0EZajK0. This key is not known by any other names Are you sure you want to continue connecting (yes/no/[fingerprint])? yes Warning: Permanently added 'ssh.devcloud.intel.com' (ED25519) to the list of known hosts.

Intel Distribution OpenVINO Toolkit 2022.1 is available!

For more information, do take a look at Intel® Distribution of OpenVINO™ Toolkit

Updated, Cleaner API

  • The new OpenVINO API 2.0 was introduced, which aligns OpenVINO inputs and outputs with frameworks. Input and output tensors use native framework layouts and element types. 
  • The API parameters in Model Optimizer have been reduced to minimize complexity. Performance has been significantly improved for model conversion on Open Neural Network Exchange (ONNX*) models.

Broader Model Support

  • With Dynamic Input Shapes capabilities on CPU, OpenVINO is able to adapt to multiple input dimensions in a single model providing more complete NLP support. Support for Dynamic Shapes on additional XPUs is expected in a future dot release.
  • New models with a focus on NLP and a new category, Anomaly Detection, and support for conversion and inference of select PaddlePaddle* models:
    • Pretrained models for anomaly segmentation focus on industrial inspection making speech denoising trainable, plus updates on speech recognition and speech synthesis
    • Combined demonstration that includes noise reduction, speech recognition, question answering, translation, and text to speech
    • Public models with a focus on NLP ContextNet, Speech-Transformer, HiFi-GAN, Glow-TTS, FastSpeech2, and Wav2Vec

Portability and Performance

  • New AUTO plug-in self-discovers available system inferencing capacity based on model requirements so applications no longer need to know their compute environment in advance.
  • Automatic batching functionality via code hints automatically scale batch size based on XPU and available memory.
  • Built with 12th generation Intel® Core™ processors (formerly code named Alder Lake) in mind. Supports the hybrid architecture necessary to deliver enhancements for high performance inferencing on CPUs and integrated GPUs.

Compiling Singularity-CE-3.10.0 on Rocky Linux 8

The Official Documentation can be found at https://sylabs.io/guides/3.0/user-guide/installation.html

Prerequisites 1 – Go

Go to the Download Page https://go.dev/dl/ to download the Linux Version.

Extract the archive you downloaded into /usr/local, creating a Go tree in /usr/local/go.

This step below will remove a previous installation at /usr/local/go, if any, prior to extracting. Please back up any data before proceeding.

% rm -rf /usr/local/go && tar -C /usr/local -xzf go1.18.3.linux-amd64.tar.gz

Add /usr/local/go/bin to the PATH environment variable. You can do this by adding the following line to your $HOME/.profile or /etc/profile (for a system-wide installation):

export PATH=$PATH:/usr/local/go/bin

Verify the Installation with the command

% go version

Compiling Singularity

To download Singularity, do visit the download site. Singularity uses a build system called makeit. mconfig is called to generate Makefile and them make is used to compile and install

% git clone https://github.com/sylabs/singularity.git --recurse-submodules
% cd singularity
% ./mconfig --prefix=/usr/local/singularity-ce-3.10.0
% cd builddir
% make
% make install
.....
.....
 checking: header linux/securebits.h... yes
 checking: header linux/capability.h... yes
 checking: libseccomp+headers... yes
 checking: conmon source... no

conmon source not found

Unless you are building --without-conmon you must 'git clone --recurse-submodules'
or 'git submodule update --init'.

You may want to install glib2-devel, delete the singularity directory and make the singularity again. 

% dnf install glib2-devel

Remote the cloned singularity directory and git clone again

% rm -Rv --force singularity
% git clone https://github.com/sylabs/singularity.git --recurse-submodules

Recompile with mconfig again. If successful, it should be something like

=> generating fragments ...
=> building Makefile ...
=> generating singularity-ce.spec ...
=> project singularity-ce setup with :
    - host arch: x86_64
    - host wordsize: 64-bit
    - host C compiler: cc
    - host Go compiler: /usr/local/go-1.18.3/bin/go
    - host system: unix
      ---
    - target arch: x86_64
    - target wordsize: 64-bit
    - target C compiler: cc
      ---
    - config profile: release
      ---
    - SUID install: yes
    - Network plugins: yes
    - seccomp support: yes
    - Build conmon: yes
      ---
    - verbose: no
      ---
    - cryptsetup: /usr/sbin/cryptsetup
      ---
    - version: 3.10.0+21-g1b1a05ff8

% cd builddir
% make
% make install

Testing

As long as you see a cow your installation is working properly…….

% singularity run library://godlovedc/funny/lolcow
< Exercise caution in your daily affairs. >
