efficiency, but requires less resource overhead (memory and CPU), so most of the slob is used in embedded systems, but the current embedded system computing power is generally strong, So slob basically out of the historical stage.Memory Policies: PolicyBecause of the advent of NUMA, it is necessary to allow the user program to control where its memory is applied. Mpol_default, mpol_preferred, Mpol_interleave, and mpol_bind, memory policies inherit from the parent process.The memory used can als

, there are other similar mechanisms, such as EVMS, Dmraid. But LVM is widely used.Working styleThis mechanism cannot be done only in user space and requires code assistance in kernel space, which is Device-mapper (Dm_mod module). The Dm_mod module completes the conversion of the IO request, which is essentially a mapping as in memory management. The code is located in DRIVER/MD. This part of the code is a vivid embodiment of the separation of policy and mechanism, the policy is specified by the

corresponding interrupt processing function, processing multi-CPU access and interrupt re-entry problems, and then invoke the real interrupt processing function, that is, the upper layer of interrupts. However, the kernel makes a difference here, if the kernel determines if the interrupt has been nested (at the same time more interrupts), the interrupt handler function is run as a kernel thread, otherwise it will run directly. So, we can often see in the output of the PS command:These soft inte

First, the topic requirementsTitle: Returns the number of the largest sub-arrays in a two-dimensional integer array. Requirements: Enter a two-dimensional shape array with positive and negative numbers in the array. A two-dimensional array is connected to the end of the line, like a belt. One or more consecutive integers in an array make up a sub-array, each of which has a and. The maximum value for the and of all sub-arrays.Requires a time complexity of O (n). Second, the design idea first call

elements. The maximum range that can be computed is 10,0000, and it takes about half a minute to calculate the 10,0000. In addition to the computed range, it is almost equal to the dead loop and the operation time is too long.Solution: The solution to the direct response is to change int to longint or to a wider range of other types. Teacher Example Hospital Medical insurance system, the content of the query display year divided into monthly display, narrow the display, reduce the display conte

key point in cubic is that its window growth function depends only on the time interval value of the successive two congestion events, thus the window growth is completely independent of the network latency RTT, and the hstcp described earlier has a serious RTT inequity, The independent nature of the rtt of the cubic allows cubic to maintain a good RTT fairness between multiple TCP connections that share a bottleneck link.Stcp,scalable TCP.The STCP algorithm was proposed by Tom Kelly in 2003 to
