The cluster architecture of Filecoin miners determines its core performance.
Homogeneous clusters and heterogeneous clusters
Heterogeneous clusters-computing belongs to computing, storage belongs to storage
(1) Heterogeneous cluster architecture
Usually consists of Miner (a master node composed of Intel chips or AMD chips + multiple GPUs) and Worker (AMD worker + Intel chip worker processing the sealing process) + storage cabinet (storage of sealed sectors).
(2) Mining process
The mining process of this heterogeneous cluster is roughly as follows:
After the computing server performs the P1, P2, C1, and C2 phase calculations (some heterogeneous clusters with intel chip machines, the last three processes of these four processes will be transmitted to the intel computing server for the last three calculations and then stored Into the storage cabinet). ; Store the sealed sectors in the storage array cabinet, and then the main server performs Winpost calculations on the sectors of the storage array cabinet; the amount of data that needs to be transmitted during the whole process is relatively large, and it needs to be upgraded with 10 Gigabit Ethernet ports.

(3) Analysis of advantages and disadvantages
What are the advantages of such a cluster solution configuration?
Advantage:
●Each process is assigned to the most suitable machine to speed up the sealing process.
●The cost structure will be reduced and the use of GPUs will be reduced. A GPU master node can bring storage cabinets with large storage, and the cost of a single T is relatively low. Home ipfsguanfang understands
● The cost of later expansion is low.
Disadvantages:
●The process of sealing needs to transmit a large amount of data, the transmission time is long, and it is necessary to break through the transmission I\O bottleneck.
●Too customized, difficult to deal with the risks and changes of mining. The software maintenance cost is high and the complexity is high.
● Seems to save costs, other I\O bottlenecks, software complexity and difficulty of operation and maintenance are not low in cost.
This is a heterogeneous cluster. The current technically very good team mainly uses heterogeneous clusters, including the top running teams in the current test rankings, so the advantages of heterogeneous clusters are believed to be highly regarded by many teams.
Homogeneous cluster computing and storage integration
(1) Homogeneous cluster architecture
Next, let's talk about a homogeneous cluster, which is usually composed of Miner+Miner. Each of the clusters is a separate master node, full AMD chip server. The CPU is responsible for the sealing, and the GPU is responsible for the latter stages of the sealing and the calculation of the sealed space-time proof and block generation. Usually a MINER can bring 192T space, local computing and local storage, and then miner is added when it is full, which can be expanded infinitely.
(2) Mining process
The mining process of homogeneous clusters is relatively simple. The entire sealing process: P1, P2, C1, C2 are all running on the same server. Except for the P1 process, the following processes are accelerated by GPU. The local storage is packaged locally, and there is no need to transmit large amounts of data. The GPU is sealed After the sector is completed, Winpost calculation is performed to obtain a block.
(3) Analysis of advantages and disadvantages
To sum up, because the whole architectural ideas are completely different, the properties of the entire solution will be very different. The reason why homogeneous clusters and single machines are more respected is because of the following three points:
1. It is more in line with the more decentralized and sufficiently decentralized characteristics of the blockchain, because every machine can run, and the nodes will be more decentralized. Home ipfsguanfang understand
2. The investment risk factor of the 24 disk 4U machine is the lowest. If the FIL price drops below the shutdown price or there is a Filecoin imitation project with better returns in the market, the whole machine can be switched over. Heterogeneous clusters cannot work. Heterogeneous clusters need to be modified for projects, and the cost of modification may be very high. Isomorphic clusters do not need to be modified, and it is very easy to switch directly and 4U machines to do POC mining, and it has many advantages over 2U12 disk machines.
3. The simplification of mining software and mine management software allows unlimited expansion and easy online management of tens of thousands of mining machines.
Advantage:
●Local calculation and local storage, saving transmission time.
●Software operation and maintenance is low in difficulty, conducive to cluster management, and easy to expand.
●Strong anti-risk ability. Once the FIL currency price does not perform well, more FIL imitations and POCs can be cut, plus the matching mining of the mining pool, there is almost no possibility of loss.
Compared with any one in a heterogeneous cluster, the sealing efficiency is much higher.
Of course, things have two sides, and homogeneous clusters also have disadvantages.
Disadvantages:
●The cost of a single unit is higher than that of a heterogeneous cluster, and GPU usage is more than that of a heterogeneous cluster.
● Relatively made storage solutions are not the current mainstream cloud computing storage solutions.
This is the difference and comparison of advantages and disadvantages between heterogeneous clusters and homogeneous clusters, which are relatively clear.
PART 02
Popularization of important concepts about computing power
1. Cloud computing power
Since the computing power of filecoin starts from 0, it takes a long time for the computing power to be stored for a long time to cash out the effective computing power of 10T. So almost all the spaces are sold, and it takes a long time to store up these spaces.
2. Effective computing power
Only after sealing can be called effective computing power, because Filecoin's effective sealing can be called effective computing power, it takes a long process to accumulate the effective computing power of Filecoin, so basically the purchased computing power actually takes a lot of money to redeem such a large computing power. Long time.
3. How much computing power does a cluster have
In fact, Filecoin's cloud computing power should not use T as a unit at all, it should use shares as a unit. It is necessary to figure out the machine composition of the cluster and how many shares there are in a cluster. This is to figure out the bottom layer, and then it can be transparent. .
Summary: It's not that you can't buy it with computing power. It's the key to figure out the corresponding mining machine. For everyone, the transparent concept of cloud space computing power, effective computing power and cluster computing power is proposed.
