这是memory不足造成的吗？
[英]Is this caused by insufficient memory?
问题描述
This problem occurred when I used chipyard to compile Boom.
这个问题是我用chipyard编译Boom的时候出现的。 Is this because of insufficient memory?这是因为memory不足吗？ I am running on a 1 core 2G cloud server.我在 1 核 2G 云服务器上运行。
/bin/bash: line 1: 9986 Killed java -Xmx8G -Xss8M -XX:MaxPermSize=256M -jar /home/cuiyujie/workspace/Boom/chipyard/generators/rocket-chip/sbt-launch.jar -Dsbt.sourcemode=true -Dsbt.workspace=/home/cuiyujie/workspace/Boom/chipyard/tools ";project utilities; runMain utilities.GenerateSimFiles -td /home/cuiyujie/workspace/Boom/chipyard/sims/verilator/generated-src/chipyard.TestHarness.LargeBoomConfig -sim verilator" /home/cuiyujie/workspace/Boom/chipyard/common.mk:86: recipe for target '/home/cuiyujie/workspace/Boom/chipyard/sims/verilator/generated-src/chipyard.TestHarness.LargeBoomConfig/sim_files.f' failed make: *** [/home/cuiyujie/workspace/Boom/chipyard/sims/verilator/generated-src/chipyard.TestHarness.LargeBoomConfig/sim_files.f] Error 137
When I adjusted the memory to 4G, this appeared.当我将memory调到4G时，出现了这个。
Done elaborating.
There is insufficient memory for the Java Runtime Environment to continue.
Should I adjust to 8G memory, or through what command to increase the memory size that the process can use?我应该调整到8G memory，还是通过什么命令增加进程可以使用的memory大小？
When I adjusted the memory to 16G, this appeared.当我将memory调到16G时，出现了这个。
/bin/bash: line 1: 2642 Killed java -Xmx8G -Xss8M -XX:MaxPermSize=256M -jar /home/cuiyujie/workspace/Boom/chipyard/generators/rocket-chip/sbt-launch.jar -Dsbt.sourcemode=true -Dsbt.workspace=/home/cuiyujie/workspace/Boom/chipyard/tools ";project tapeout; runMain barstools.tapeout.transforms.GenerateTopAndHarness -o /home/cuiyujie/workspace/Boom/chipyard/sims/verilator/generated-src/chipyard.TestHarness.LargeBoomConfig/chipyard.TestHarness.LargeBoomConfig.top.v -tho /home/cuiyujie/workspace/Boom/chipyard/sims/verilator/generated-src/chipyard.TestHarness.LargeBoomConfig/chipyard.TestHarness.LargeBoomConfig.harness.v -i /home/cuiyujie/workspace/Boom/chipyard/sims/verilator/generated-src/chipyard.TestHarness.LargeBoomConfig/chipyard.TestHarness.LargeBoomConfig.fir --syn-top ChipTop --harness-top TestHarness -faf /home/cuiyujie/workspace/Boom/chipyard/sims/verilator/generated-src/chipyard.TestHarness.LargeBoomConfig/chipyard.TestH

Short anwer: yes简短回答：是的
Error 137 is thrown when your host runs out of memory .当您的主机用完 memory时，将引发Error 137 。
"I am running on a 1 core 2G cloud server"
When you try to assign 8GB to the JVM, OOM-Killer says "no-no, f... no way" , and kicks in sending a SIGKILL ;当您尝试将8GB分配给 JVM 时， OOM-Killer会说“不，不，f...没办法” ，并开始发送SIGKILL ； This Killer is a proactive process that jumps in to save the system when its memory level goes too low, by killing the resource-abusive processes .这个 Killer 是一个主动进程，当它的 memory 级别过低时，它会通过杀死资源滥用进程来拯救系统。
In this case, the abusive process ( very abusive, indeed ) is your java program, which is trying to allocate more than(*) 4 times the maximum avaliable memory in your host .在这种情况下，滥用进程（确实非常滥用）是您的 java 程序，它试图分配超过（*） 4 倍于您主机中最大可用 memory 的程序。
Exit Codes With Special Meanings 具有特殊含义的退出代码
[error code 137 --> kill -9] (SIGKILL)
You should either:您应该：
Assign at max ~ 1.2GB - 1.5GB to your process.
最多为您的进程分配 ~ 1.2GB - 1.5GB 。 ( and keep your fingers crossed ) （并保持你的手指交叉）Change your host for something a little powerful/bigger, if you do require that much memory for your process.
如果您的进程确实需要那么多 memory，请将您的主机更改为更强大/更大的东西。Check if you really require 8GB for that process .
检查您是否真的需要 8GB 来执行该过程。
Also note that the given params are error prone: Xmx8G -Xss8M means maximum of 8GB and a minimum of 8M for the heap.另请注意，给定的参数容易出错：Xmx8G -Xss8M 表示堆的最大值为 8GB，最小值为 8M。 This should be closer, as Xmx8G - Xms4G这应该更接近，因为Xmx8G - Xms4G
* As the free memory won't be 2GB either, but something in between 1.6-1.8 GB *因为免费的 memory 也不会是 2GB，而是介于 1.6-1.8 GB 之间
