java - NetLogo HPC 内存错误

Question

#!/bin/bash
#$ -N para_three
#$ -q all.q
#$ -pe mpi 30
/home/abhishekb/netlogo/netlogo-5.2.0/netlogo-headless.sh \
    --model /home/abhishekb/models/try4.nlogo \
    --experiment experiment1 \
    --table /home/abhishekb/csvresults/24.04_Results.csv 

错误:

Exception in thread "JobThread" 
Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "JobThread"
Exception in thread "JobThread" 
Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "JobThread"
Exception in thread "JobThread" 
Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "JobThread"

为什么，我不明白？我找到了关于使用 64 位 java 运行 NetLogo 的建议。但链接[1] [2]已过期，请帮忙。

令人惊讶的是，早些时候我在 NetLogo 5.1 上运行它并且从未遇到此错误。

脚本更改:我尝试在末尾添加线程:

#!/bin/bash
#$ -N para_three
#$ -q all.q
#$ -pe mpi 30
/home/abhishekb/netlogo/netlogo-5.2.0/netlogo-headless.sh \
    --model /home/abhishekb/models/try4.nlogo \
    --experiment experiment1 \
    --table /home/abhishekb/csvresults/24.04_Results.csv \
    --threads 30

错误消息涉及 PermGen，因此这意味着问题不是堆的总大小，而是具体的 PermGen 上限。您需要使用更高的 PermGen 设置来启动 Java，例如-XX:MaxPermSize=512m。您的 netlogo-headless.sh 文件中可能已经有这样的设置；如果是这样，请增加它。如果还没有这样的设置，请添加一个。

我大约 98% 确信这与 NetLogo 5.1 和 5.2 之间的任何差异无关。您现在使用 5.2 所做的事情和当时使用 5.1 所做的事情可能还有其他不同之处(可能是 threads= 设置的大小)。

以下是 NetLogo 5.2 的默认 netlogo.sh 和 netlogo-headless.sh 文件的工作链接:https://github.com/NetLogo/NetLogo/blob/5.2.0/dist/netlogo.sh , https://github.com/NetLogo/NetLogo/blob/5.2.0/dist/netlogo-headless.sh

运行 64 位 JVM 与解决 PermGen 问题并不特别相关，但对于运行非常大的堆可能是必要的。
