XMRigCC

About XMRigCC

XMRigCC is a fork of XMRig which adds the ability to remote control your XMRig instances via a Webfrontend and REST api. This fork is based on XMRig (2.4.4) and adds a "Command and Control" (C&C) server, a daemon to reload XMRig on config changes and modifications in XMRig to send the current status to the C&C Server. The modified version can also handle commands like "update config", "start/stop mining" or "restart/shutdown" which can be send from the C&C-Server.

Full Windows/Linux compatible, and you can mix Linux and Windows miner on one XMRigCCServer.

Additional features of XMRigCC (on top of XMRig)

• Command and control server
• CC Dashboard with:
  • statistics of all connected miners
  • remote control miners (start/stop/restart/shutdown)
  • remote configuration changes of miners

Also you can use configuration via config file, default config.json. You can load multiple config files and combine it with command line options.

Multihash (multihash-factor)

With this option it is possible to increase the number of hashblocks calculated by a single thread in each round. Selecting multihash-factors greater than 1 increases the L3 cache demands relative to the multihash-factor. E.g. at multihash-factor 2, each Cryptonight thread requires 4MB and each Cryptonight-lite thread requires 2 MB of L3 cache. With multihash-factor 3, they need 6MB or 3MB respectively.

Setting multihash-factor to 0 will allow automatic detection of the optimal value. Xmrig will then try to utilize as much of the L3 cache as possible for the selected number of threads. If the threads parameter has been set to auto, Xmrig will detect the optimal number of threads first. After that it finds the greatest possible multihash-factor.

Multihash for low power operation

Depending the CPU and its L3 caches, it can make sense to replace multiple single hash threads with single multi-hash counterparts. This change might come at the price of a minor drop in effective hash-rate, yet it will also reduce heat production and power consumption of the used CPU.

Multihash for optimal CPU exploitation

In certain environments (e.g. vServer) the system running xmrig can have access to relatively large amounts of L3 cache, but may has access to only a few CPU cores. In such cases, running xmrig with higher multihash-factors can lead to improvements.

Multihash thread Mask (only for multihash-factor > 1)

With this option you can limit multihash to the given threads (mask). This can significantly improve your hashrate by using unused l3 cache. The default is to run the configured multihash-factor on all threads.

{
...

"multihash-factor":2,
"multihash-thread-mask":"0x5", // in binary -> 0101
"threads": 4,

...
}

This will limit multihash mode (multihash-factor = 2) to thread 0 and thread 2, thread 1 and thread 3 will run in single hashmode.

Common Issues

XMRigMiner

• XMRigMiner is just the worker, it is not designed to work standalone. Please start XMRigDaemon instead.

Windows only: DLL error on starting

• Make sure that you installed latest Visual C++ Redistributable for Visual Studio 2015. Can be downloaded here: microsoft.com

Linux only: Background mode

• The --background option will only work properly for the XMRigServer. But there is a simple workaround for the XMRigDaemon process. Just append an & to the command and it will run smoothly in the background.

  ./xmrigDaemon --config=my_config_cc.json & or you just use screen

HUGE PAGES unavailable (Windows)

• Run XMRig as Administrator.
• Since version 0.8.0 XMRig automatically enables SeLockMemoryPrivilege for current user, but reboot or sign out still required. Manual instruction.

HUGE PAGES unavailable (Linux)

• Before starting XMRigDaemon set huge pages

  sudo sysctl -w vm.nr_hugepages=128

Other information

• No HTTP support, only stratum protocol support.
• No TLS support.

CPU mining performance

Please note performance is highly dependent on system load. The numbers above are obtained on an idle system. Tasks heavily using a processor cache, such as video playback, can greatly degrade hashrate. Optimal number of threads depends on the size of the L3 cache of a processor, 1 thread requires 2 MB (Cryptonight) or 1MB (Cryptonigh-Lite) of cache.

Maximum performance checklist

• Idle operating system.
• Do not exceed optimal thread count.
• Use modern CPUs with AES-NI instruction set.
• Try setup optimal cpu affinity.
• Try decreasing number of threads while increasing multihash-factor. Allocate unused cores and L3 cache with the help of multihash-thread-mask.
• Enable fast memory (Large/Huge pages).
