How to evaluate computing power

1. 1. The meaning of CPU calculation once is that CPU performs "bit calculation" once, for example, 2 + 3 = 5, and binary is 0010 + 0011 = 0101. If there are three bits in total, the computer will calculate three times. 2. As for what this number is related to, that is, the higher the CPU frequency, the more the number of operations per unit time
2.
The development of single CPU can not meet the needs of practical applications, and the AI era must rely on parallel computing. At present, the mainstream architecture of parallel computing is heterogeneous parallel computing platform. If you need the service of computing power, you can go to the tenth power
3. If you want to trade this computing power, you can trade it online. You can trade it on their app
4. N card directly ignores
a card, that is to say, it depends on the frequency and SP
,
the better the a card, the stronger the mining.

6. 1. If there are multiple cubes in your cube, then follow the mouse model, use ray on the model, and the cube touched by ray changes (such as color darkening)
2. Draw multiple cubes, arrange them in order, name them, and remove the meshender attribute (no rendering), which is equivalent to drawing a grid, which is easy to understand
3. It's troublesome to judge the range with two-dimensional array (mainly integer), The simple way is that the computer obtains the original coordinates of the model (such as the center point of the model). When the absolute value of the x value (and y value) of the mouse's real-time coordinates minus the original coordinates is equal to the side length of the square, the square (or other dry points) will be displayed with the real-time coordinates as the center, The real-time coordinates are used as the original coordinates for the next step

capacity Scheler supports the following features:
(1) Computing power guarantee. Support multiple queues, a job can be submitted to a queue. Each queue is configured with a certain proportion of computing resources, and all jobs submitted to the queue share the resources in the queue< br />(2) Flexibility. Idle resources will be allocated to those queues that do not reach the upper limit of resource usage. When a queue that does not reach the upper limit of resource needs resources, once there are idle resources, they will be allocated< br />(3) Priority is supported. Queue supports job priority scheling (FIFO by default)
(4) Multiple leases. Considering a variety of constraints to prevent a single job, user or queue from monopolizing the resources in the queue or cluster< br />(5) Resource based scheling. It supports resource intensive jobs, allows jobs to use more resources than the default value, and can accommodate jobs with different resource requirements. However, only memory resource scheling is currently supported< br />3. Analysis of computing power scheler algorithm
3.1 The variables involved
in capacity, there are three kinds of granularity objects: queue, job and task. They all need to maintain some information:
(1) Queue maintenance information
@ queuename: the name of the queue
@ ulmin: the minimum amount of resources available for each user (all users are the same), which needs to be specified by the user in the configuration file
@ capacitypercent: to calculate the resource proportion, and
@ numjobsbyuser: the workload of each user in the configuration file to track the workload submitted by each user, And limit the quantity
attributes of map or rec task in the queue:
@ capacity: the actual amount of computing resources, which changes dynamically with the number of slots in the tasktracker (users may be adding or recing machine nodes), The size is: capacitypercent * mapclustercapacity / 100
@ numrunningtasks: the number of running tasks
@ numslotsoccupied: the total number of slots occupied by running tasks. Note that in the capacity Scheler, running tasks and slots do not necessarily correspond one by one, and each task can obtain multiple slots, mainly because the scheling supports memory resource scheling, A task may require the amount of memory contained in multiple slots
@ numslotsoccupiedbyuser: the total number of slots occupied by each user's job is used to limit the amount of resources used by users< br />(2) Job maintenance information
priority: job priority, divided into five levels, from large to small in order: very_ HIGH，HIGH，NORMAL，LOW，VERY_ LOW;
nummaptasks / numrecetasks: the total number of map / rec tasks of the job
runningmaptasks / runningmaptasks: the number of map / rec tasks that the job is running
finishedmaptasks / finishedrecetasks: the number of map / rec tasks that the job has completed
...
(3) Task maintenance information
task start time, current status, etc.
3.2 Computing power scheling algorithm
when there is an idle slot on a tasktracker, the scheler selects a queue, a job in the selected queue, and a task in the selected job in turn, and assigns the slot to the task. The following describes the strategy used to select queue, job and task:
(1) Select queue: sort all the queues according to the resource utilization (Num slots occupied / capacity) from small to large, and process them in turn until a suitable job is found< br />2 Select job: in the current queue, all jobs are sorted according to the job submission time and job priority (assuming that priority scheling function is enabled, which is not supported by default and needs to be enabled in the configuration file). Scheling considers each job in turn, Select a job that meets two conditions: [1] the user where the job is located does not reach the upper limit of resource utilization [2] the node where the tasktracker is located has enough memory for the task of the job< br />3 Select a task. Like most schelers, consider the locality and resource usage of the task That is: call the obtainnewmaptask() / obtainnewrecetask() method in jobinprogress)
in summary, the pseudo code of fair scheler is:
/ / capacitytasks cheler:trackTracker When a free slot appears, find the appropriate task for the slot
List & lt; Task> assignTasks(TaskTrackerStatus taskTracker) {
sortQueuesByResourcesUsesage(queues);< br />
for queue:queues {

8. The cube of a cuboid is volume: length × wide × High
cube is volume: edge length x edge length x edge length.
cube is volume: edge length x edge length x edge length.
9. At present, everyone's evaluation of him is quite good. This platform now has many users, the transactions in it are very safe and transparent, and the threshold is also very low.
10. Considering that you claim to be road blind, I'll give you a simpler route
1. Take Shanghai Nanjing Expressway to Nanjing toll station
2. After passing Nanjing toll station, turn right at the first intersection (Maqun overpass) and go to the ring road to the Second Yangtze River Bridge. Be careful not to go straight to the urban area, because no foreign motor vehicles are allowed on Zhongshan East Road. As soon as you get out of Nanjing toll station, walk on the right. As soon as you see the right ramp, turn right
3. Turn left on the ring road of the first overpass (dongyangfang overpass) after you get on the ring road. Go to Xuanwu Avenue and Xinzhuang. Note that this is a cloverleaf interchange. If you want to turn left, take the second right ramp of the interchange. After you go down, make a circle and you can drive to the left
4. Next, just follow the lane closest to the center line to jiangdongbei road. Along the way, you will encounter two viacts, one overpass (Xinzhuang overpass) and two tunnels (Xuanwu Lake Tunnel and model road tunnel). Out of the model road tunnel, continue to pass the model Road West, Dinghuaimen, Dinghuaimen street
5. At the intersection of Dinghuaimen street and Jiangdong North Road, turn left and go straight south to the Olympic Sports Center. This road will pass Jiangdong North Road and Jiangdong middle road. The cross roads are: Caochangmen street, Qingliangmen street, Hanzhongmen street, Shuiximen street, Jiqingmen street, Yingtian street, Xinglong Street and Meng street. The Olympic Sports Center is at the intersection of Jiangdong middle road and Meng street
in the case of the hotel, there is a "Zixin International Hotel" on the opposite side of the Olympic sports and a "Zhenbao Holiday Hotel" on the north side. As for whether it's good or not, I don't know. I don't go there very often.
