carried out on. If we want to parallel all the data ahead of time, the number of cores and the number of threads per core are very important.
AM negotiates resources with YARN based on resource management of user resource requests (number of parameter servers and threads, memory, and GPUs)
The cost of this transaction can be divided into two parts of the content. The first part is the verification of the legitimacy of the Bitcoin transaction itself, the verification of the script, the signature, the verification of the amount. The second part is double-flower/UTXO verification.
When processing packets on a live network, you can now specify how many threads to use instead of using the same number of I/O threads.
H.SIG (r, 1, Q (r-1)) s (a(i,r) / M) (1 / SIZE (PK(r-k))
Note that the script here is not a script like Linux bash, but a simple virtual machine language, like JVM, which has built-in a miniature set of instructions that can perform simple operations such as numerical operations, comparisons, signature verification, and so on.
Hyperthreading means that better load distribution is achieved when the processor virtually splits each physical core into two virtual cores. Operating system threads are created and managed within the operating system, where each thread executes its own code and takes turns running on the virtual kernel. Most operating systems actually make the number of threads unlimited, but unfortunately starting them is expensive because it requires an allocation stack. Green threads are implemented by the user software and run on top of the OS thread. The advantage of green threads is that they work even in environments that are not supported by OS threads;
There was a previous case in which the number of system threads was 1000 plus, and jstack analyzed that more than 900 threads were in blockED and WAITING states, which do not consume CPU.
Technically, Dogecoin is actually a faction with Litecoin, which is based on the Scrypt algorithm and, like Litecoin, is easier to trade than Bitcoin, and they have more numbers, with Dogecoin digging up to 100 billion, compared with 21 million bitcoins.
In fact, this is an illusion, the number of threads is not equal to the number of CPUs, a single CPU will share the CPU time slice between multiple threads, within a given time slice to perform the switch between each thread, each thread can also be executed by a different CPU, as shown in the following illustration.
dogecoin number of script verification threads
The script can include the CHECKMULTISIG operator code, which provides signature verification of n-of-m: you can provide multiple public key ms, define the number of valid signatures that must appear n, and sign n can be less than the number of public keys m. If we set up the following script, two signatures are required for one output.
Cash, Bitcoin SV, Dash, Dogecoin, IOTA, Litecoin, Monero, XRP and Zcash.
Give a script and access enough private key sets to construct a universally satisfactory witness (verification content) for it
