Question

这是我使用的工作脚本，

#!/bin/bash
#PBS -q batch
#PBS -N simulation
#PBS -j n
#PBS -o /dev/null
#PBS -l nodes=1:ppn=1,pmem=3400mb
#PBS -l ncpus=1,mem=3400mb

cd ${PBS_O_WORKDIR} && \

./executable

我收到此错误：

Operating system error: Cannot allocate memory
Allocation would exceed memory limit

我尝试增加ppn和ncpus以及mem以使其符合我的程序要求（~6GB）。也没帮助。

当我在终端中运行命令时，不会发生这种情况。它运作得很好。

尝试运行程序，将系统中的所有内存分配给作业。然后最后执行lpszDriver，查看Torque对已用资源的看法。

[DllImport("gdi32.dll", SetLastError = true, CharSet = CharSet.Auto)]
internal static extern IntPtr CreateDC(string lpszDriver, string lpszDevice, string lpszOutput, IntPtr lpInitData);

[DllImport("gdi32.dll", SetLastError = true, EntryPoint = "DeleteDC")]
internal static extern bool DeleteDC([In] IntPtr hdc);  

public static IntPtr CreateDCFromDeviceName(string deviceName)
{
    return CreateDC(deviceName, null, null, IntPtr.Zero);
}


Screen[] screens = Screen.AllScreens;
IntPtr screenDC1 = CreateDCFromDeviceName(screens[0].DeviceName);
IntPtr screenDC2 = CreateDCFromDeviceName(screens[1].DeviceName);
using (Graphics g1 = Graphics.FromHdc(screenDC1))
using (Graphics g2 = Graphics.FromHdc(screenDC2))
using (Pen pen = new Pen(Color.Red, 10))
{
    g1.DrawRectangle(pen, new Rectangle(new Point(100, 100), new Size(200, 200)));
    g2.DrawRectangle(pen, new Rectangle(new Point(100, 100), new Size(200, 200)));
}

DeleteDC(screenDC1);
DeleteDC(screenDC2);

当我作为一个que（PBS / Torque）提交时，作业与OOM崩溃但是当我运行时只是在终端中运行命令时崩溃
