【问题描述】：
这个问题是我用chipyard编译Boom的时候出现的。这是因为内存不足吗？我在 1 核 2G 云服务器上运行。
/bin/bash: 第 1 行：9986 杀死 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 ";项目实用程序；运行主要实用程序.GenerateSimFiles -td /home/cuiyujie/workspace/Boom/chipyard/sims/verilator/generated-src/chipyard.TestHarness.LargeBoomConfig -sim验证器” /home/cuiyujie/workspace/Boom/chipyard/common.mk:86：目标配方 '/home/cuiyujie/workspace/Boom/chipyard/sims/verilator/generated-src/chipyard.TestHarness.LargeBoomConfig/sim_files.f' 失败的 make: *** [/home/cuiyujie/workspace/Boom/chipyard/sims/verilator/generated-src/chipyard.TestHarness.LargeBoomConfig/sim_files.f] 错误 137
当我把内存调到4G的时候，出现了这个。
完成详细说明。 OpenJDK 64 位服务器虚拟机警告：信息： os::commit_memory(0x00000006dc3b7000, 97148928, 0) 失败； error='无法分配内存' (errno=12)

我应该调整到8G内存，还是通过什么命令增加进程可以使用的内存大小？
当我把内存调到16G的时候，出现了这个。

【问题讨论】：
-
原来的命令是make CONFIG=LargeBoomConfig。我是否更改为 CONFIG=LargeBoomConfig -Xmx6G -Xss3G？
-
是的，或者在执行过程时通过命令行：
java -Xms3G -Xmx6G yourprogam.java -
请注意，我的错误是写 -Xss 而应该是 -Xms （第一个用于堆，这里暂时不涉及）
-
-Xms3G-- 为 JVM 分配最少 3GB-Xmx6G-- 为 JVM 最多分配 6GB -
make：无效选项 -- 'G'。发生这种情况。
