Question

我的工作站使用 2 个 Xeon CPU，具有 24 核 48 线程。我在我的工作站上配置了 slurm.conf 如下：

*

为了运行我的计算代码 (OpenMP)，我使用了下面的批处理文件。但是，当我提交的作业脚本的数量为--cpus-per-task而不是20（例如：12、30或40）时，代码运行时间很慢？？？

#!/bin/bash
#
#SBATCH --job-name=testOMP # Job name
#SBATCH --nodes=1 # Run all processes on a single node
#SBATCH --ntasks=1 # Run a single task
#SBATCH --cpus-per-task=20 # Number of CPU cores per task
#SBATCH --hint=nomultithread # Get physical cores not logical
#SBATCH --exclusive # Job memory request (All available memory)
#SBATCH --time=20:00:00 # Time limit hrs:min:sec
#SBATCH --output=omp%j.out # Name of output file
#SBATCH --error=omp%j.out # Name of error file
# cleans out modules loaded by default
module purge
# load modules
module load intel
# echo of launcher commands
set -x
# number of OMP threads
export OMP_NUM_THREADS=$SLURM_CPUS_PER_TASK
# Binding
export OMP_PLACES=cores
./2D-TFlow2Wall-UPWIND-HKO

此外，工作站总共有 32Gb，但我无法指定要使用的内存量。该程序仅自动使用 2Gb。

你能不能就这些问题给我一个建议！非常感谢！
