/* * Thread configuration for each thread. Make sure it matches the number above. * low_power_mode - This mode will double the cache usage, and double the single thread performance. It will * consume much less power (as less cores are working), but will max out at around 80-85% of * the maximum performance. * * no_prefetch - Some sytems can gain up to extra 5% here, but sometimes it will have no difference or make * things slower. * * affine_to_cpu - This can be either false (no affinity), or the CPU core number.

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