我收到一个 403 Forbidden 错误。
-
Markdown 不支持代码高亮，添加任何语法规范都会导致
403 Forbidden错误。 -
内联代码段在某些位置（而非全部位置，相对于其他代码块）也会导致
403 Forbidden错误。
安装的版本是 3.1.1 ( 0612f0d5b6 )。
这些问题是相关的吗？可能是什么原因导致这种行为？
示例帖子： Compiling OpenFOAM with Spack - 📚 Knowledge nuggets - HPC discourse
预期结果：
在使用 Spack 安装 OpenFOAM of OpenCFD 时出现了一些问题。
按照 UL HPC 教程中的说明，设置了一个环境来管理 Spack 的软件包。简而言之，为 SPACK 软件包定义了以下依赖项：
(access node)$ cat << EOF > $SPACK_ROOT/etc/spack/packages.yaml
packages:
slurm:
externals:
- spec: slurm@22.05.5
prefix: /usr
buildable: False
libevent:
externals:
- spec: libevent@2.1.8
prefix: /usr
buildable: False
pmix:
externals:
- spec: pmix@4.2.3
prefix: /usr
buildable: False
hwloc:
externals:
- spec: hwloc@2.2.0
prefix: /usr
buildable: False
EOF
并为构建缓存目录定义了以下选项：
(access)$ cat << EOF > $SPACK_ROOT/etc/spack/config.yaml
config:
build_stage:
- /dev/shm/$user/spack-stage
EOF
以使用内存盘文件系统加速编译。在继续安装 OpenFOAM 之前，使用系统编译器安装所需的 Open MPI 版本：
(compute node)$ spack install -j openmpi@4.0.5 +pmi schedulers=slurm ^pmix@4.2.3 ^hwloc@2.2.0
OpenFOAM 发行版也使用系统编译器进行安装。OpenFOAM 的可用组件是：
(access node)$ spack list openfoam@2306

OpenFOAM 使用所有可用的分区器（metis、scotch、zoltan、kahip）和多网格生成器组件（文档第 6.3.1.4 节）进行安装，命令如下：
(compute node)$ spack install -j openfoam@2306 +source precision=dp +metis +scotch +zoltan +kahip +mgridgen ~knl ~int64 ~paraview ^openmpi@4.0.5
然而，由此产生的安装缺少多个组件。例如，执行 doc/Build.md 中的手动安装后验证：
# Create the user "run" directory:
mkdir -p "$FOAM_RUN"
# Change to the user "run" directory:
run
# Copy tutorial
cp -r "$FOAM_TUTORIALS"/incompressible/simpleFoam/pitzDaily ./
# Run the tutorial
( cd pitzDaily && blockMesh && simpleFoam )
网格生成器 blockMesh 和求解器 simpleFoam 都丢失了。
事实证明，METIS 分区器导致多个组件的安装失败。仅使用 SCOTCH 分区器重新编译：
(compute node)$ spack install openfoam@2306 +source +scotch +mgridgen precision=dp ~int64 ~kahip ~knl ~metis ~paraview ~vtk ~zoltan ^openmpi@4.0.5
解决了这个问题。所有求解器组件都已安装，但仍缺少一些实用程序。
我们使用以下脚本来检测所有缺失的组件：
(access node)$ cat list_spack_openfoam
#!/usr/bin/bash
set -euo pipefail
declare variant="${1}" # e.g. @2306%gcc@8.5.0 @2306+mgridgen
declare type="${2}" # solvers, utilities
find_makefile_directories() {
local directory="${1}"
find "${directory}" -type d | grep -E '\/Make$' || true
}
extract_executable_name() {
local makefile_directory="${1}"
cat "${makefile_directory}/files" | ( grep -E '^EXE[[:space:]]*=' || true ) | sed 's/^EXE[[:space:]]*=[[:space:]]*\$(FOAM_APPBIN)\///g'
}
main() {
local variant="${1}"
local type="${2}"
local foam_location="$(spack location -i openfoam"${variant}")"
local pagkage_directory=""
local executable_name=""
local installed=""
local package_makefile_directory=""
while read -r package_makefile_directory; do
executable_name=$( extract_executable_name "${package_makefile_directory}" )
if [ -n "${executable_name}" ]; then
if [ -x "${foam_location}/platforms/linux64GccDPInt32-spack/bin/${executable_name}" ]; then
installed="Y"
else
installed="N"
fi
package_directory="$( echo "${package_makefile_directory}" | xargs -I % dirname % )"
echo "${installed} : ${executable_name} => ${package_directory#${foam_location}}"
fi
done < <( find_makefile_directories "${foam_location}/applications/${type}" )
}
main "${variant}" "${type}"
运行该脚本的简单测试表明，以下实用程序缺失：
(access node)$ ./list_spack_openfoam utilities @2306 | grep -E '^N'
N : addr2line => /applications/utilities/miscellaneous/OSspecific/addr2line
N : foamyHexMeshSurfaceSimplify => /applications/utilities/mesh/generation/foamyMesh/foamyHexMeshSurfaceSimplify
