3. Alter the GRUB bootloader configuration file to enable hugepages and set driver parameters. This is done by changing the GRUB_CMDLINE_LINUX_DEFAULT parameter in the file “/etc/default/grub”. The provided parameter was my entire parameter setting.
* "```maybe-ubiquity```" was present by default.
* The hugepage parameters "```default_hugepagesz=1G hugepagesz=1G hugepages=1```" set 1GB hugepage by default and enables 1 hugepage. Tests showed that the application only used 1 hugepage. Set more if needed, but the more you set the more memory will be unavailable by your OS when mounting (see step 5).
* ```iommu``` parameters "```iommu=pt iommu=on intel_iommu=on```" are for enabling the vfio-pci (and uio_igb) driver that was used by DPDK in the thesis.
* "```default_hugepagesz=1G hugepagesz=1G hugepages=1```" set 1GB hugepage by default and enables 1 hugepage. Tests showed that the application only used 1 hugepage. Set more if needed, but the more you set the more memory will be unavailable by your OS when mounting (see step 5).
* "```iommu=pt iommu=on intel_iommu=on```" are for enabling the vfio-pci (and uio_igb) driver that was used by DPDK in the thesis.
* "```isolcpus=4,10,5,11```" isolate logical cpu cores and prevents the OS from using the logical cores. Add the cores you would like to use in your application here. The thesis used logical cores 4, 5, 10 and 11 that was used to run the DPDK application on.
* Use ```lscpu``` or ```lstopo``` to see how many logical cpu cores your computer have.
