Normally, only Chameleon users with active allocations are able to launch and view Trovi artifacts. To allow anyone to launch an artifact, we also provide daypass. This allows for a non-Chameleon user to have access to Chameleon for a limited amount of time, using a small, separate allocation. People interested in reproducing your project will send requests to the managers of a project. If approved, the requesting user will receive an email invitation to join a reproducibility project. When they accept, they can use this project to run your artifact. After the specified time limit, they will be automatically removed from this project. Daypass can be enabled on an artifact-by-artifact basis in Trovi.

Allowing Reproducibility Requests

First, the owner of an artifact must permit reproducibility requests. This can be revoked at any time, preventing future requests. Additionally, you must also give your artifact a value for “Hours a user has to reproduce.” This value specifies how long a user will have access to Chameleon for. Consider how long it takes to run your experiment from start to finish as a lower bound for this value. The artifact owner must also assign their artifact to a project via the dropdown selector. As these requests are granting access to Chameleon resources, this is needed to tie granted requests to a PI.

These fields can be accessed by navigating to an artifact’s detail page, and then selecting “Share.” At the bottom of the share page, you will see the below forms, which are the project assignment, the enabling of reproducibility requests, and the hours to reproduce.

After these items are saved, a reproducibility allocation request is automatically made under your PI’s name. Your artifact should now appear with a “Request Daypass” button below the “Launch” button. The “Launch” button will not appear for users that are not a member of an active Chameleon project.

Requesting a Daypass

When another researcher wishes to reproduce your artifact (or when you wish to do so for another’s artifact), selecting “Request Daypass” will display a form asking for a name, institution, and the reason for reproducing the artifact. For artifacts under your project/allocation, this gives you oversight and discretion as to who you grant access to, as ultimately you’re responsible for usage under your allocation (including reproducibility allocations). For artifacts you wish to explore, it gives you the chance to reach out to the project owners and explain why you are interested in their work.

After submitting the form, the managers (and PI) of the project associated with the artifact will receive an email informing them of the request.

Reviewing a Daypass Request

After receiving an email with the daypass request, PIs and project managers can navigate to the review page by clicking the link in the email. Here, they will see all of the details submitted with the request. A decision can be made by choosing “approved” or “rejected” in the selector, and then clicking submit.

After this decision is made, an email is sent to the requestor with the result. If the request is approved, an invitation is sent to the user.

Using an Invitation

If your daypass request is approved, an email will be sent to you with an invite link. After clicking this link, you will be automatically added to the project. The email will also mention how long the invitation is for. When the invite is accepted, you will be taken to the project page for the reproducibility project. Please note the ID of the project (CHI-XXXXX), which may be needed to configure an artifact.

Next, you can navigate back to the original artifact URL you were given. The “Launch” button can be used now to start running the artifact.

After the duration for the invite has passed, you will be automatically removed from the project.
