mining - Beowulf Cluster - Ethereum Stack Exchange

Magic Arena completely destroyed my ¢500,000 Beowulf cluster.

I have a custome Beowulf cluster that I use for modeling the universe and bitcoin mining sometimes I play magic arena on a Mac OS VM in it and magic arena cause the whole thing to literally melt because wizards hire script kiddies instead of real programmers, and the app isn’t written in a stable language like assembly.

Quantum1Net: The Why, The How, The What! Part #3

Quantum1Net: The Why, The How, The What! Part #3
A short history of distributed and decentralized solutions.
Distributed computing was first suggested and tested in the 60s when Ethernet was developed. But it was not really formally defined until 1982 when the first distributed conference was conducted in Canada, where various architectures were defined the two most known being Clustering and Peer2Peer. Clustering to achieve faster calculations, or data sharing, was used by NASA early as it was the best way to optimize the usage of the servers. The first and most known open source clustering tool was released by NASA in 1994 and described as “Beowulf is a multi-computer architecture which can be used for parallel computations”. Peer2Peer was made popular in 2010 with file sharing solutions and it is said that at that time more then half of the Internet traffic was the peer2peer exchange of files.
In 2009 Satoshi Nakamoto released Bitcoin and gave the world a “trustless’ decentralized digital currency that is controlled by no bank, government or institution. The blockchain – the immutable ledger that records all Bitcoin transactions - was something very new, solving at a stroke the difficult and longstanding problem of creating a trustless source of the truth for transactions. The connections between Bitcoin nodes are not encrypted, but the ownership of ‘addresses’ in the network can be proven by the usage of private cryptographic keys in a Public Key Infrastructure (PKI). Hence the term cryptocurrency. Quantum1Net merges Clustering, Peer2Peer and Cryptocurrency to create a new paradigm for Cloud services, an autonomous self-healing decentralized overlaying network, with additional features as enhanced security by protection from Quantum Computer Enhanced Hacking, privacy by personal control of your data, stability by using AI to chose best data paths, and performance enhanced by a private data routing system.
This gives users the freedom to safely transmit data over Quantum1Net securely and to publish websites and any other existing Internet services using secure communication channels. Also to develop completely new services and applications that run only on Quantum1Net via Application Programming Interfaces (APIs) which enables easy development, integration, and deployment. Just like any kind of application can run on your local file system, any kind of application can run on Quantum1Net's Decentralized Service Platform.

Trying to run a simulated Bitcoin network to test blocktime

I am trying to use a beowulf cluster to simulate different blocktimes and how they affect the networks efficiency. Currently I am using the bitcoin-cpp API from minium and trying to forcefully restart the daemon and delete the mempool.dat file to clear the mempool in between tests. I'm have a hell of a lot of issues fails after a few trys. Is there better way to be doing something like this?
Edit: forgot to mention I are using regtest

Simulating the Bitcoin Blockchain on a Cluster

I am trying to simulate the Bitcoin Blockchain using regtest for research reasons but am having lots of trouble. I have a beowulf cluster that I am trying to run the simulation on. For some specifics I am trying to rapidly send transactions and generate blocks with specified block times. I am using MPI in C++ with bitcoin-cpp-api to attempt this. Can anyone suggest a better or more simple way of approaching this? How would you go about this?

Can a Beowulf Cluster be designed to mine Etherium and thus do away with the need of 'hard to get' GPU's that are also becoming expensive? I've seen the RasberryPI Beowulf Cluster but I was not able to discern if it can be applied to mining etherium. mining. share improve this question follow asked Feb 13 '18 at 13:03. Zoref Zoref. 11 1 1 bronze badge. add a comment 1 Answer Active ... You can create a Beowulf cluster with just a few crap computers and an ethernet segment in your backyard. Although they don’t give you top-notch performance, their performance is many-fold better than a single computer. A variant of Beowulf Clusters allows OS to run on every node and still allow parallel processing. And this is what exactly we’re going to do here. Kick Start Your Cluster ... Coordinating with the head of district for my school, I've been granted permission to make a Beowulf cluster, using one, two or three tutorials. But, the compute possibilities aren't clearly defined, and I'm confused. What I know: You can't run GPU dependent games across the cluster ; You can't run non multi-threaded applications across the cluster I am going to attempt to setup a Beowulf cluster on 3 Fedora 21 systems. The base instructions I will be using are from the following 2 sources: A Beowulf cluster is just a bunch of networked Linux boxes with MPI installed. Oh, and a really spiffy name. Report comment.
