scalarm_simulation_manager_go

Scalarm Simulation Manager is a Scalarm Platform worker component that manages computations on various computational resources. This version is written in Go.

Installation guide:

Go

To build and install Scalarm Workers Manager you need to install go programming language. You can install it from official binary distribution:

https://golang.org/doc/install

or from source:

https://golang.org/doc/install/source

This command will install Scalarm Simulation Manager in $GOPATH/bin. It's name will be scalarm_simulation_manager.

Config

Configuration is read from config.json file that contains required informations for Scalarm Simulation Manager:

• experiment_id (string) - optional, if not specified, all user's experiment in random order will be computed
• information_service_url (string)
• experiment_manager_user (string)
• experiment_manager_pass (string)
• development (bool)
• start_at (string)
• timeout (int)
• scalarm_certificate_path (string)
• insecure_ssl (bool)
• simulations_limit (int) - optional, if specified, execute max. N simulations

Command line options

• -simulations_limit <N> (int) - optional, if specified, execute max. N simulations. Note, that it overrides simulations_limit from config.json.

Run

Before running program you have to copy contents of config folder to folder with executable file of Scalarm Simulation Manager. By default it will be $GOPATH/bin

Testing

To run all test execute in the main directory

go test -v ./...
