  3. * Thread configuration for each thread. Make sure it matches the number above.
  4. * low_power_mode - This mode will double the cache usage, and double the single thread performance. It will
  5. * consume much less power (as less cores are working), but will max out at around 80-85% of
  6. * the maximum performance.
  7. *
  8. * no_prefetch - Some sytems can gain up to extra 5% here, but sometimes it will have no difference or make
  9. * things slower.
  10. *
  11. * affine_to_cpu - This can be either false (no affinity), or the CPU core number. Note that on hyperthreading
  12. * systems it is better to assign threads to physical cores. On Windows this usually means selecting
  13. * even or odd numbered cpu numbers. For Linux it will be usually the lower CPU numbers, so for a 4
  14. * physical core CPU you should select cpu numbers 0-3.
  15. *
  16. * On the first run the miner will look at your system and suggest a basic configuration that will work,
  17. * you can try to tweak it from there to get the best performance.

  21. * [
  22. * { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 0 },

  33. * LARGE PAGE SUPPORT
  34. * Lare pages need a properly set up OS. It can be difficult if you are not used to systems administation,
  35. * but the performace results are worth the trouble - you will get around 20% boost. Slow memory mode is
  36. * meant as a backup, you won't get stellar results there. If you are running into trouble, especially
  37. * on Windows, please read the common issues in the README.
  38. *
  39. * By default we will try to allocate large pages. This means you need to "Run As Administrator" on Windows.
  40. * You need to edit your system's group policies to enable locking large pages. Here are the steps from MSDN
  41. *
  42. * 1. On the Start menu, click Run. In the Open box, type gpedit.msc.
  43. * 2. On the Local Group Policy Editor console, expand Computer Configuration, and then expand Windows Settings.
  44. * 3. Expand Security Settings, and then expand Local Policies.
  45. * 4. Select the User Rights Assignment folder.
  46. * 5. The policies will be displayed in the details pane.
  47. * 6. In the pane, double-click Lock pages in memory.
  48. * 7. In the Local Security Setting – Lock pages in memory dialog box, click Add User or Group.
  49. * 8. In the Select Users, Service Accounts, or Groups dialog box, add an account that you will run the miner on
  50. * 9. Reboot for change to take effect.
  51. *
  52. * Windows also tends to fragment memory a lot. If you are running on a system with 4-8GB of RAM you might need
  53. * to switch off all the auto-start applications and reboot to have a large enough chunk of contiguous memory.
  54. *
  55. * On Linux you will need to configure large page support "sudo sysctl -w vm.nr_hugepages=128" and increase your
  56. * ulimit -l. To do do this you need to add following lines to /etc/security/limits.conf - "* soft memlock 262144"
  57. * and "* hard memlock 262144". You can also do it Windows-style and simply run-as-root, but this is NOT
  58. * recommended for security reasons.
  59. *
  60. * Memory locking means that the kernel can't swap out the page to disk - something that is unlikey to happen on a
  61. * command line system that isn't starved of memory. I haven't observed any difference on a CLI Linux system between
  62. * locked and unlocked memory. If that is your setup see option "no_mlck".

  66. * use_slow_memory defines our behaviour with regards to large pages. There are three possible options here:

  69. * no_mlck - This option is only relevant on Linux, where we can use large pages without locking memory.
