The CPU rx configuration was set in the “short object format” shown here to ease configuring the number of threads on larger instances.1gb-pages under randomx is set to true.Some key changes as compared to the default file includes: XMRIG configuration is defined via a config.json file in the same directory as the executable. make -j$(nproc) Configuring and executing XMRIG
#Xmr hash calculator install
sudo apt-get update sudo apt-get install git build-essential cmake libuv1-dev libssl-dev libhwloc-dev git clone mkdir xmrig/build & cd xmrig/build cmake.
#Xmr hash calculator code
For the instances with AMD and ARM processors the steps below were used to build the code as instructed here and shown below. For the Intel based processors (C5, M5, etc), the pre-compiled binary was used. Release 6.9.0 of XMRIG was used in all of the experiments. sudo chmod 600 YOUR_AWS_KEY.pem Installing XMRIG ssh -i "YOUR_AWS_KEY.pem" you receive the error Permissions 0777 for 'YOUR_AWS_KEY.pem' are too open run the command below to restrict key permissions. To access your newly created instance, use the command below. Allow SSH access to the instance by opening port 22 to “my IP” under the “source” column.We will be keeping everything to default settings. Skip “Step 3: Configure Instance Details”.Note: If launching on an ARM processor choose the ARM version of the OS. Select the “Ubuntu Server 20.04 LTS (HVM), SSD Volume Type” operating system.
Click “Launch Instance” from the EC2 dashboard.The AWS EC2 instances were created in the US-EAST-1 region via the admin console following the steps below: Both the rental cost of the instances as well as the earnings from generated Monero will be shown. In the next sections, we will review the mining performance using AWS EC2 servers. Both the data and instructions are defined via a randomly generated bitstream that is stored in 2080 MB of RAM. Instead, of relying on a hashing function that executes the same sequence of instructions on differing data, this algorithm randomizes both the data and the instructions (sequence of operations) that are used. This algorithm benefits from two properties of CPUs: The ability to execute arbitrary instructions and access to large amounts of memory. To achieve this goal, the cryptocurrency Monero makes use of the RandomX algorithm. Since a large number of ideally decentralized miners are required in order to secure the blockchain (no double spending, etc), there is an incentive to benefit mining via common hardware (CPU) versus specialized hardware (GPU, FPGA, ASIC). Cryptocurrency mining can be thought of as the execution of work by an agent that contributes to the confirmation of transactions.
