在OSX 10.12上使用mmap()时出现Get 'cannot allocate‘错误

在OSX 10.12上使用mmap()时出现"cannot allocate"错误是由于内存不足导致的。mmap()是一种内存映射文件的方法,它将文件映射到进程的地址空间,以便可以像访问内存一样访问文件。当调用mmap()时,操作系统会尝试将文件映射到进程的虚拟内存中,但如果系统内存不足,就无法分配足够的内存来完成映射操作,从而导致"cannot allocate"错误。

解决这个问题的方法有以下几种:

  1. 增加系统内存:如果你的系统内存不足,可以考虑增加内存条的容量,以提供足够的内存供应给mmap()使用。
  2. 减少内存占用:在使用mmap()之前,可以尝试减少当前进程的内存占用,关闭一些不必要的应用程序或进程,释放内存资源。
  3. 优化代码:检查代码中是否存在内存泄漏或者不必要的内存占用,优化代码逻辑,减少内存使用量。
  4. 调整mmap()参数:可以尝试调整mmap()函数的参数,例如调整映射文件的大小或者调整映射的起始地址,以适应当前系统内存的限制。

    iomem=str mem=str Fio can use various types of memory as the io unit buffer. The allowed values are: malloc Use memory from malloc(3) as the buffers. shm Use shared memory as the buffers. Allocated through shmget(2). shmhuge Same as shm, but use huge pages as backing. mmap Use mmap to allocate buffers. May either be anonymous memory, or can be file backed if a filename is given after the option. The format is mem=mmap:/path/to/file. mmaphuge Use a memory mapped huge file as the buffer backing. Append filename after mmaphuge, ala mem=mmaphuge:/hugetlbfs/file mmapshared Same as mmap, but use a MMAP_SHARED mapping. The area allocated is a function of the maximum allowed bs size for the job, multiplied by the io depth given. Note that for shmhuge and mmaphuge to work, the system must have free huge pages allocated. This can normally be checked and set by reading/writing /proc/sys/vm/nr_hugepages on a Linux system. Fio assumes a huge page is 4MB in size. So to calculate the number of huge pages you need for a given job file, add up the io depth of all jobs (normally one unless iodepth= is used) and multiply by the maximum bs set. Then divide that number by the huge page size. You can see the size of the huge pages in /proc/meminfo. If no huge pages are allocated by having a non-zero number in nr_hugepages, using mmaphuge or shmhuge will fail. Also see hugepage-size. mmaphuge also needs to have hugetlbfs mounted and the file location should point there. So if it'smountedin/huge,youwouldusemem=mmaphuge:/huge/somefile.iomem_align=intThisindiciatesthememoryalignmentoftheIOmemorybuffers.NotethatthegivenalignmentisappliedtothefirstIOunitbuffer,ifusingiodepththealignmentofthefollowingbuffersaregivenbythebsused.Inotherwords,ifusingabsthatisamultipleofthepagesizedinthesystem,allbufferswillbealignedtothisvalue.Ifusingabsthatisnotpagealigned,thealignmentofsubsequentIOmemorybuffersisthesumoftheiomem_alignandbsused.hugepage-size=intDefinesthesiz
