处理大数据 [英] handling large data
问题描述
有人请告诉我如何处理int 2000 * 2000的数组数据吗？
即使使用超级计算机进行文件传递，似乎calloc失败并且
分割试运行期间的错误结果。

有人请告诉我如何处理int 2000 * 2000的数组数据？
即使使用超级计算机进行文件传递，看来calloc失败并且
分段错误结果在试运行期间。
发生错误：
gcc -O3 -Wall -I。 vote.c datamanager.c -o vote -L。 -hhungarian
gcc：内部错误：分段错误（程序cc1）

* 2000？即使使用超级计算机进行文件传递，似乎在试运行期间，b / b
calloc失败并出现分段错误结果。
假设你有一个相当正常的系统，其sizeof int == 4，那个
数组需要4,000,000 * 4或16 GB的内存。请注意，
保证可用大小为65k（对于C99）和32k（对于C90）。
许多系统将为您提供2千兆字节，但只有64位
系统将允许16场演出。
寻找另一种机制。

Would anybody please tell me how to handle array data of int 2000 * 2000?
Even make file passes by using a supercomputer, it seems calloc fails and
segmentation fault results during a trial run.

Maybe it ran out of space?

Put the data in a files and read it in at runtime instead of using
static initialisation.

calloc fails and segmentation fault results during a trial run.Assuming you have a fairly normal system with sizeof int == 4, that
array requires 4,000,000 * 4, or 16 gigabytes of memory. Note that
the guaranteed available size is 65k (for C99) and 32k (for C90).
Many systems will give you 2 gigabytes, but only some 64 bit
systems will allow 16 gigs.
Look for another mechanism.
