# BRUTEX CAVIS Build Requirements # You can build CAVIS on either x86_64 linux or x86_64 windows (sometimes referred to as amd64). Support for native GPU (CUDA) or CPU (AVX2/ AVX512) support can be enabled. Linux on x86_64 is the primary target platform. CAVIS is written in Java, C, C++ and Kotlin, therefore you will need a Java JDK and C/C++ compiler. # Table of contents 1. [Introduction](#introduction) 2. 2. [Some paragraph](#paragraph1) 1. [Sub paragraph](#subparagraph1) 3. [Another paragraph](#paragraph2) ## Build Environment Prerequisites CAVIS uses the [Gradle Build Tool](https://gradle.org) and [CMake](https://cmake.org/) to execute the build. A Gradle Wrapper is provided, that will pull the right version of gradle. ### Linux x86_64 Prerequisites Linux Kernel 5.10 or higher **Required build tools:** | Tools | Version | Remarks | |----------|------------|--------------------------------------------------| | Gradle | \> 7.2 | | | CMake | \> 2.24.10 | | | GNU Make | 3.82 | | | Compiler | Version | Remarks | | -------- |----------------|---------------------------------------------------| | GCC | 7.3.1 - 10.2.1 | C and C++ compiler | | nvcc | \> 11.4 | only in case you want to compile for CUDA support | | javac | JDK 11 | openjdk-11 | #### Amazon Linux 2 #### Preparation shell script ```shell sudo amazon-linux-extras install java-openjdk11 && \ sudo yum install --assumeyes git make gcc gcc-c++ openssl-devel java-11-openjdk-devel && \ wget https://github.com/Kitware/CMake/releases/download/v3.24.2/cmake-3.24.2.tar.gz && \ tar -xf cmake-3.24.2.tar.gz && cd cmake-3.24.2/ && \ ./bootstrap && make && sudo make install && cd .. ``` In case you have less than 8GB RAM, a swap file should be created ```shell sudo dd if=/dev/zero of=/swapfile count=8k bs=1M && sudo chmod 600 /swapfile && \ sudo mkswap /swapfile && sudo swapon /swapfile ``` You can make the swap change permanent (surviving a reboot) by putting it into /etc/fstab file. ```shell echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab ``` In order to resolve Brutex Network IP6 endpoints, you need to add an additional nameserver ```shell echo 'nameserver 8.8.8.8' | sudo tee -a /etc/resolv.conf ``` ## Some paragraph The first paragraph text ### Sub paragraph This is a sub paragraph, formatted in heading 3 style ## Troubleshooting ### Gradle process just crashes ### This is likely an out-of-memory problem, check ```shell dmesg ``` for ``` oom-kill:constraint=CONSTRAINT_NONE,nodemask=(null),cpuset=/,mems_allowed=0,global_oom,task_memcg=/,task=java,pid=16477,uid=1000 [ 6291.694315] Out of memory: Killed process 16477 (java) total-vm:11373580kB, anon-rss:1373168kB, file-rss:0kB, shmem-rss:0kB, UID:1000 pgtables:11220kB oom_score_adj:0 ``` and increase i.e. swapfile size (by adding another one). sudo apt-get -q update ret=$? while [ $ret -ne 0 ]; do echo Waiting for instance to be ready ... sleep 20s sudo apt-get -q update ret=$? done echo Instance is ready. #Create swap echo Adding swap file sudo fallocate -l 16G /swapfile sudo chmod 600 /swapfile sudo mkswap /swapfile sudo swapon /swapfile echo Swap created. #echo "deb http://deb.debian.org/debian/ buster main" | sudo tee /etc/apt/sources.list #echo "deb http://deb.debian.org/debian/ buster main contrib non-free" | sudo tee -a /etc/apt/sources.list sudo apt-get -q --yes install build-essential default-jdk git ninja-build gnupg software-properties-common snapd make g++-multilib g++ g++-8 gcc gcc-8 libopenblas-base libopenblas-dev ret=$? while [ $ret -ne 0 ]; do echo Waiting for instance to be ready ... sleep 20s sudo apt-get -q --yes install build-essential default-jdk git ninja-build gnupg software-properties-common snapd make g++-multilib g++ g++-8 gcc gcc-8 libopenblas-base libopenblas-dev ret=$? done #sudo snap install core #sudo snap install cmake --classic wget https://github.com/Kitware/CMake/releases/download/v3.20.4/cmake-3.20.4-linux-x86_64.sh chmod a+x cmake-3.20.4-linux-x86_64.sh sudo sh cmake-3.20.4-linux-x86_64.sh --skip-license echo "supersede domain-name-servers 172.31.0.2, 8.8.8.8" | sudo tee -a /etc/dhcp/dhclient.conf echo "nameserver 8.8.8.8" | sudo tee -a /etc/resolv.conf # Buildparameter: # -P\\ CAVIS_AVX_EXTENSION = {avx2 | avx512}, default is avx2 # Zeppelin Spark dependencies # 3 To add the dependency to the language models, use the following format in the Dependencies section of the of the Spark Interpreter configuration (Interpreters -> Spark -> Edit -> Dependencies): groupId:artifactId:packaging:classifier:version In your case it should work with edu.stanford.nlp:stanford-corenlp:jar:models:3.8.0
