CAMERA allows users to run their own Kepler workflows on the CAMERA cluster in a special Sandboxed environment. Kepler workflows are a flexible tool for accessing scientific data (metagenomics, streaming sensor data, medical and satellite images, simulation output, observational data, etc.) and executing complex analysis on the retrieved data.
For a lot of problems it is an easier way to create a program then writing software in a traditional programming language.
There are several reasons to run a workflow on the CAMERA cluster:
By default an individual user workflow job run is limited to:
Exceeding these constraints will cause the termination of the workflow and possibly loss of any results. Currently there is no limit to the number of user workflow jobs that can be run, but this is a shared resource and activity deemed as abuse or overuse may result in termination of jobs.
It is the name of the environment we use to run the workflows in on the CAMERA cluster. Every workflow job is run under a special restricted environment we call a "sandbox" with limited access to linux binaries and filesystems. This is done for security reasons and prevents a workflow job from seeing data it is not supposed to access or from effecting any other workflow job or the cluster.
Not for user workflows, but we are working on it.
You do. We only run the job for you. Hence any action your workflow performs, malicious or not is your responsibility. Uploading a workflow implies your agreement to this.
