This article tests three compilers, namely VC, mingw, and GCC, in 32-bit and 64-bit modes. In six cases, the predefined macro values related to 64-bit programming are used. It is of reference significance for cross-platform programming.

Three tasks to be completed in DIY data analysis system.
1. Use VMware to install 64-bit CentOS. The database server can use the built-in CentOS.

Oracle Data is divided into 32-bit and 64-bit, which correspond to different platforms. For details about how to check whether the database is 32 or 64-bit, refer:

to find out the cause. In example 1, there are many violations of this rule, which need to be rewritten when transplanted to a 64-bit platform.
Example 1:

between the operating system and other applications, this virtual memory limit always exists. On the other hand, 64-bit applications are compiled based on the 64-bit 8-byte memory. More than 4 GB of virtual memory can be used, which is not limited. The operating system usually imposes more virtual memory limits on app
likely to be introduced over the years with the addition and deletion of the program modules.We ported this 32-bit program to the 64-bit platform to take advantage of the advanced aspects of 64-bit technology-supporting larger files, supporting larger memory, and

At the reader's request, phoronix.com recently conducted a special performance test on the Linux kernel, comparing the performance of 32-bit, 32-bit physical address extension (PAE), and 64-bit. Linus Torvalds, the father of Linux systems, once said that there is a 25% performance difference between the system kernel t

CONFIG_HIGHMEM4G is enabled for the 32-bit Ubuntu kernel by default, but the PAE mode is disabled. In this way, when the system configures 4 GB memory, 1 GB is reserved
