我正在服务器(64GB内存)上使用java OpenMPI来排序一个大整数数组(长度为10亿).
但是当我增加数组的长度时,我得到这个错误:
A fatal error has been detected by the Java Runtime Environment:
…
Failed to write core dump. Core dumps have been disabled. To enable core dumping,try “ulimit -c unlimited” before starting Java again
最佳答案
核心转储(在Unix术语中),内存转储或系统转储包括特定时间计算机程序的工作存储器的记录状态,通常是在程序崩溃或以其他方式异常终止时.
请参考Core dump.
请参考Core dump.
