size, assuming that the main memory is divided into 300 (1~300) blocks, and the cache is divided into 10 (1~10) blocks for illustration.(1) Full-linked mappingAny block of 1~300 in main memory can be mapped to any piece in the cache1~10, which is characterized by simple, but low-efficiency lookups.(2) direct-linked mappingsSuppose that the 1~30 block in main memory can only be mapped to the cache's block 1th, and so on. This results in a high efficiency compared to full-phase lookup, which can

1G, the mapping here may involve PAE and high-end memory , detailed reference to high-end memory . 2.6 Linear addresses of fixed mappings The 0~896m space used to map RAM. 2.7cache and LTB The most commonly used parts of the data structure are placed in front of the position, while trying to adjacent, thereby using the cache line. CR3 updates often also imply a flush of TLB, except for the following: 1) Switch between processes in two shared Pag

for all page boxes, and a writeback policy is always used for write operations. 5. Convert Backup buffer tlb: In addition to hardware caching, a TLB cache is used to speed up the conversion of linear addresses. page pagination in 5.Linux The role of the Linux paging mechanism: The paging mechanism is done after the segment mechanism, which further converts the linear address to the physical address. Let's

802.3AD specification. The slave election for outgoing traffic is based on the transport hash policy, which can be changed from the default XOR policy to other policies through the Xmit_hash_policy option. It should be noted that not all transport strategies are 802.3AD compliant, especially given the problem of packet chaos mentioned in the 802.3AD standard 43.2.4 section. Different implementations may have different adaptations. Prerequisites: Conditional 1:ethtool Support gets the rate and d

ADO I see an article abroad, now translates as follows ... It certainly helps. One drawback of ASP is that when we are using a component, we are not going to get it. For example, when you want to use ADO, you must first include the Adovbs.inc file Or do a similar job, look at the following code: Dim objconn, strSQL Set objconn = Server.CreateObject ("ADODB. Connection ") objConn.Open "Dsn=blah" strSQL = "SELECT * FROM Table1" Dim objRS Set objRS = Server.CreateObject ("ADODB. Recordset ") Ob

provides fault tolerance means support for 802.3AD protocol, and aggregation of switches L ACP mode Fit (requires Xmit_hash_ Policy). Standard requires all devices to be in the same rate and duplex mode when aggregating operations, and, as with other bonding load balancing modes other than BALANCE-RR mode, no connection can use more than one interface's bandwidth. creates an aggregation group that shares the same rate and duplex settings. Multiple slave are working under the same active aggr

The Linux bonding driver provides 7 modes, namely: BALANCE-RR, Active-backup, Balance-xor, broadcast, 802.3AD, Balance-tlb, Balance-alb.BALANCE-RR or 0: Polling mode, which provides load balancing and fault tolerance. Two network ports in this mode are workingActive-backup or 1: Primary and Standby switching mode, provides redundancy, the mode only one network port work, the other to do backup.Balance-xor or 2: Based on the hash algorithm load Balanci

, last_pkmap_nr equals to 1 during the first allocation. Next, determine when last_pkmap_nr is equal to 0. If it is equal to 0, the 1023 (LAST_PKMAP (1024)-1) page table items have been allocated. In this case, call the flush_all_zero_pkmaps () function, flush the entries in the TLB for all the page table items with the pkmap_count [] count as 1 and reset them to 0, which means that the page table items can be used again, I may wonder why I didn't f

previous page size is 4 MB in large memory pages, the same 1 GB memory can be mapped with only 256 page table entries, without 262,144. In this way, the overhead is changed from 2 MB to 2,048 bytes. The use of large memory pages can also improve performance by reducing the number of translation index buffer (TLB) failures. TLB is a kind of high-speed cache for page tables, so that the pages listed in the

small and one large memory page size. On x86, the size of a large memory page is 4 MB, or 2 MB on the system opened by the physical address extension (PAE. Assuming that the previous page size is 4 MB in large memory pages, the same 1 GB memory can be mapped with only 256 page table entries, without 262,144. In this way, the overhead is changed from 2 MB to 2,048 bytes. 　　 The use of large memory pages can also improve performance by reducing the number of translation index buffer (

Download source code I. PrefaceSome time ago, due to busy work, I was not able to write in time. In the meantime, I received a letter from many netizens asking and encouraging me. I would like to express my gratitude to you here. Cough... I also need a job to support my family ......The previous response introduced two methods to write component programs for the automated (idispatch) interface. One is to write the "pure" idispatch interface in the MFC mode; the second is to use the ATL method to

want. This is called "interface transmission"7,C/C ++ must declare the function in advance.The component must also provide the header file of the C language. No! In order to enable com to have cross-language capabilities, it is decided not to provide the corresponding function interface declaration for any language, but to independently provide a Type Library(TLB) statement. The IDE environment of each language generates the packaging required by its
