写在前面

本方案, 是假定您的计算机技能, 停留在多数简历里面描述的“熟练掌握Micosoft Word, PowerPoint, Excel; 会使用Origin绘图, 会PhotoShop简单修图”这个水平. 但是您可以区分清楚键盘上的字母键, 数字键, 方向键, 以及粘贴完毕指令后, 还要按Enter这种操作逻辑. 

本方案半自动调试集群.

ACK集群上实现Slurm HPC & Kubernetes负载混合调度
2401_88127808的博客
12-14 1324
为什么要提出在ACK集群上实现Slurm HPC & Kubernetes负载混合调度呢？原因分析：目前ACK会提供静态分配+分离调度的方案，但是由于每个Slurm Pod的规格固定，且Slurm Pod属于提前占用集群资源，Slurm集群中资源空闲时Kubernetes无法使用这些已占用的集群资源，从而导致集群资源碎片。此外，修改Slurm Pod的资源规格需要删除Pod重建，因此在Slurm与Kubernetes资源占用变化较大的场景中，节点迁移的难度较大。

关于研讨会 摘要Slurm作业计划程序（目前由USC使用）为您的所有计算需求提供了灵活的基础架构。 从提交单核长时间运行的任务到复杂的多节点任务，Slurm涵盖了计算资源管理方面所有科学家的需求。 R编程语言尽管不支持HPC，但具有多个基于社区的解决方案，可将您的计算管道与HPC设置（包括Slurm）集成在一起。 在本研讨会中，我们将说明如何将R与USC的HPC群集一起使用，涵盖从最基本的内容（例如提交简单的R脚本）到更复杂的功能设置，例如在节点中使用数十个或数百个内核的多节点套接字群集。相同的R会话。 该研讨会将由凯克医学院的南加州大学生物统计学部门主持。 议长 网站可以在查看 快乐科学家精选：Lynn Conway 林恩·康威（Lynn Conway），2006年7月。资料来源： Lynn Ann Conway（生于1938年1月2日）是美国计算机科学家，电气工程师，发明家和变性人

LSF是一个比较主流的任务调度系统，包括深圳和苏州的超算中心都是使用的LSF系统，包括Spectrum LSF, PlatformLSF和OpenLava。我接触到的都是PlatformLSF。SGE则包括UGE和SGE，本来是开源的，但是被Oracle收购后就变成了闭源了。PBS则包括OpenPBS,PBS PRO 和Moab/TORQUE，可能由于比较老了吧，目前我没有见到了。
HPC调度基础：slurm集群的部署
天翼云开发者社区

slurm是一种开源的、具有容错性和高度可扩展的Linux集群超级计算系统资源管理和作业调度系统。具体来说，计算集群使用slurm对资源和作业进行管理和调度，减少计算任务间相互干扰，提高集群运行效率。2016年世界十大超算系统，其中就有五个是使用slurm来进行管理的，甚至有众所周知的2016年冠军超算——神威太湖之光。slurm给超算系统的提供了三个关键功能：1.为用户分配一定时间的专享或非专享的资源(计算机节点)，以执行作业（Job）2.提供了用于启动、执行、监测在节点上运行的作业的框架。

srun [options] program命令属于交互式提交作业，有屏幕输出，但容易受网络波动影响，断网或关闭窗口会导致作业中断。如果不关心节点和时间限制，可简写为srun -N 1 -n 4 hostname。使用 srun 命令，配合 -p 分区名 参数，以及 -N 节点数 -n 核心数 进行提交。mixed：混合，节点在运行作业，但有些空闲 CPU 核，可接受新作业。-w cn[01-02] 指定提交作业到cn01,cn02节点。-x cn[01-02] 排除cn01、cn02节点。

Slurm 是一个开源、容错、高度可扩展的集群管理和作业调度系统，适用于大型和小型 Linux 集群。Slurm 的操作不需要修改内核，而且相对独立。作为集群工作负载管理器，slurm 有三个关键功能。首先，它在一段时间内为用户分配对资源(计算节点)的独占和/或非独占访问权，以便他们能够执行工作。其次，它提供了一个框架，用于在分配的节点集上启动、执行和监视工作(通常是一个并行作业)。最后，它通过管理挂起的工作队列来仲裁资源争用。

在使用 SLURM 进行多节点 GPU 通信时，若遇到 NCCL 报错 `Cuda failure 400: invalid resource handle`，通常表明某个 GPU 资源句柄无效或访问异常。此类错误可能由多种因素引起，包括但不限于 CUDA 环境配置不当、GPU 资源分配冲突、NCCL 版本与 CUDA 不兼容、或 SLURM 配置未正确绑定 GPU 资源。 以下为可能的原因及解决办法： - **资源句柄无效**：该错误代码 `400` 表示“invalid resource handle”，意味着尝试访问的 CUDA 资源（如事件、流、内存等）不存在或已被释放。建议检查程序中是否重复释放了某些资源，或者在多个线程/进程中错误地共享了资源句柄 [^2]。 - **SLURM GPU 绑定问题**：确保在提交作业时通过 `--gpus-per-node` 或 `--gres=gpu:N` 正确指定了使用的 GPU 数量，并且在程序中通过 `CUDA_VISIBLE_DEVICES` 设置了正确的设备索引。例如： ```bash #SBATCH --gres=gpu:gb200:4 export CUDA_VISIBLE_DEVICES=0,1,2,3 ``` 若未正确限制可见设备，可能导致进程试图访问不属于当前任务的 GPU 设备 [^1]。 - **NCCL 和 CUDA 版本兼容性**：确保所使用的 NCCL 版本与 CUDA 工具包版本兼容。可参考 NVIDIA 官方文档确认兼容性列表。若版本不匹配，可能出现资源管理异常。构建 NCCL 时建议指定架构参数以适配 GB200 的计算能力，例如： ```bash export NVCC_GENCODE="-gencode=arch=compute_90,code=sm_90" make -j CUDA_HOME=/usr/local/cuda ``` - **多节点通信初始化失败**：在分布式训练中，NCCL 需要通过 SSH 或 MPI 正确初始化跨节点通信。确保节点间网络通畅，并使用 `nccl-tests` 或 `torchrun` / `mpiexec` 启动多节点任务时配置正确。可以先运行简单的 `all_reduce_perf` 测试验证基本通信能力 [^1]。 - **驱动和运行时状态异常**：使用 `nvidia-smi` 检查所有目标 GPU 是否处于正常状态，无显存泄漏或被其他进程占用。若存在僵尸进程，可通过 `kill -9 <pid>` 清理 [^3]。 ### 示例命令用于测试 NCCL 多节点通信 ```bash srun -N2 -n4 --gpus-per-node=4 --gpu-bind=closest ./build/all_reduce_perf -b 8 -e 512M -f 2 -g 1 ``` 上述命令表示在两个节点上各启动 4 个 GPU 进程，进行 AllReduce 性能测试，并绑定最近的 GPU 设备。 ---
