这个问题是我用chipyard编译Boom的时候出现的。 是不是因为内存不够？ 我在 1 核 2G 云服务器上运行的。

/bin/bash: line 1: 9986 Killed java -Xmx8G -Xss8M -XX:MaxPermSize=256M -jar /home/cuiyujie/workspace/Boom/chipyard/generators/rocket-chip/t-launch.jar -Dt.sourcemode=true -D**t.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

我把内存调到4G的时候就出现了这个

Done elaborating. OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00000006dc3b7000, 97148928, 0) failed; error=‘Cannot allocate memory’ (errno=12)

我应该调整到8G内存，还是通过什么命令来增加进程可以使用的内存大小？

当我把内存调到16G的时候，就出现了这个
