It uses the ``parallel`` package in R to communicate with workers on other instances. A Shiny app is used to show how to integrate a parallel backend into Shiny.\n\n## Remarks\n\nShiny server needs a good network connection. A clogged WiFi (high lag, many dropped packages) will make Shiny unresponsive.\n\n## AWS AMI\n\nFor the Dallas RUG talk, I created two public AWS AMI’s: \n- ami-c693afae / R-RStudio-Shiny\n- ami-042e106c / R-RStudio-Shiny-DallasRUG_2015-04-11\n\nIf you intend to use them, please consider editing the ``authorized_keys`` files to remove the public keys which might allow unauthorized access.\n\nI plan to update them soon after R 3.2.0 is being released.\n\n## Folder / File list\n\n- explore_makeCluster/ : step by step code examples to create connections with makeCluster\n- mandelbrot_app/ : Shiny app that calculates the area of the Mandelbrot set, uses ``foreach`` package\n- presentation/ : slides for the Dallas R Users Group presentation on April 11, 2015\n- Local Setup - Windows host.md : Windows Host / Virtual Box Ubuntu detailed setup\n\n\n## Instructions to set up Multi-node Multi-core R / Shiny\n#### Local setup\n\nFor the local setup on Windows please see the file\n[Local Setup - Windows host.md](/Local%20Setup%20-%20Windows%20host.md#multi-node-multi-core-r--shiny)\n\nSetups for OSX and Linux are not provided here (contributions welcome).\n\n\n#### Amazon EC2 setup\n\nSee slides, detailed instructions to follow.\n\n\n## Change log\n- 2015-04-12 : updated slides, this readme\n- 2015-04-11 : slides and code, AWS AMIs (see slides)\n- 2015-04-08 : initial commit for the local setup\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnumeract%2Fmultinode-multicore-r-shiny","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fnumeract%2Fmultinode-multicore-r-shiny","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnumeract%2Fmultinode-multicore-r-shiny/lists"}
