replace the bad blocks. This is why 16G of space is often only seen in 15G size. In addition, the so-called nand+ Micro Controller mode is now used in all mass storage products, such as the common SD card, can be said to be emmc a "vest." eMMC at the beginning of the design, in order to maintain compatibility with the previous Nand/nor, the use of 8 IO parallel read and write data, which in today's technical standards are undoubtedly backward. In the last 10 years, a large number of parallel in

Set the memory frequency and Nb frequency together with the multiplier.PCIe frequency: PCIe bus frequency. This option will directly affect your video card and peripheral devices. We recommend that you do not change it to reduce instability.DRAM frequency: Memory frequency (Frequency Division) setting. The Asus motherboard provide

In contrast, Microsoft Windows has more restrictions (even if it has a dedicated Windows 10 IoT for ARM ). Among all Linux distributions, Ubuntu is well-deserved. Today, Canonical officially expanded Ubuntu Core Linux to I. MX6 (ARM) ba

frequency.Therefore, the user should check whether the frequency setting is correct, whether the ratio of the video card frequency is reasonable, and whether the external frequency of the processor is high enough.The relationship between different frequencies should be handled when the video card is too frequently 3. How can I improve the performance of PCIE locking 1X?In another case, the game performance of the whole machine is greatly reduced afte

Close to the verge of collapse. Today this article is conceived in the hospital, and I am ill again. I 'd rather drop a bottle and take no medicine, but cannot access the Internet with my notebook. I can't do anything, I want to know something. I can only use 3 GB and don't dare to open a hot spot. Because no one reimbursed me for the traffic, I only had one day this weekend. It rained and I had another night. After learning about PF_RING, I was eager to do an experiment, so I ran home for verif

stepsFirst, in the VMware main Menu "WorkStation", "Virtual Machine", "Settings", the network connection mode is set to bridge mode, and the "Replication Physical network connection status" before the hook. This means that a virtual network card will be created, and all the status of the virtual network card is copied from the actual physical network card.Second, in the VMware main Menu "WorkStation", "edit", "Virtual Network Editor", select VMnet0, bridge it to "Realtek

We recommend that you select the physical network card that is connected locally. If you don't know, you can turn on your PC's network adapter to view it. For example, the name of my computer's local connection is as follows:So I chose to bridge to "Realtek PCIe GBE Family Controller". And you have t

For their old computer purchased a AMD770 motherboard, replaced on the boot that appears black screen phenomenon. According to the merchant said this is a new motherboard, should not be a quality problem, perhaps due to improper BIOS settings. The system bar to try to explore in the bios of the motherboard many times, finally found the problem. Open the Bois and enter the CHIPSET-NORTHBRIDGE-CONFIGURATION-PCI Express Configuration interface, which has one such item: "Primary video Controller",

In shutdown mode, computers that have remote Wake up or Wake on LAN options on the BIOS's power Management menu will not support remotely powering up, and if you do not have this option, do not support remote boot (if remote Wake up does not support remotely booting, please consult your hardware provider.) ) 　　How to enter the BIOS: When the computer starts, enter the BIOS setup by repeatedly pressing the "DELETE" key or the "F2" key. Usually under "Power managment", "Wake on LAN", "WOL", "Bo

total workload crash. Memory mirroring replicates memory content synchronously by providing DIMM-protected memory. When a memory failure is detected, the system swaps to a mirrored copy until the faulty DIMM is replaced. New servers on the market support local memory mirroring: Mirrors only the partial memory of the server used by the task-critical workload. Obviously, this is a way to reduce costs. Processor Subsystem Reliability The greatest threat to server reliability is when memory or p

sets of mini-batch data at the same time, and at the end of a round of mini-batch training, parameter exchange is required synchronously. The parameter Exchange in data parallelism requires that each model copy be merged with the gradient obtained in this mini-batch training to update the model, and then the latest model is pushed to each data parallel unit for the next round of calculations. How to solve the parameter exchange bottleneck to improve the performance is the most serious problem i

Disk I/O relatedThe following are some of the measures that can be optimized for disk I/O, based on the magnitude of the IOPS performance boost: 1, the use of SSD or PCIe SSD devices, at least hundreds of times times or even tens of times the IOPS increase; 2, the acquisition of the array card with the cache and the Bbu module, can significantly increase the IOPS (mainly refers to mech

space is shared with the previous business nodes in CIFS mode, and the two-tier architectures are scaled separately on demand. Second, the server's disks can support PCIe NVMe SSDs, SSDs, and hdd,s2d will default to the best-performing disks as storage bus caches (Storage bus cache), providing read/write caching for each node, as well as storing the metadata for the storage pool. This can be done automatically at configuration time or by manual desig

the Ethernet frame header. When a VLAN switch receives an Ethernet frame with a tag field, it can use this tag field to select the port to which the request is forwarded, and decide whether to remove the tag, or receive the Ethernet frame without the tag. Based on the port configuration information, decide whether to forward the frame and whether to add the tag...We say that Ethernet is a broadcast network. This Ethernet refers to the physical layer. For the link layer, it is only a part of the
