Edit your profile
- Open the avatar menu and choose Research profile.
- Set display name, institution, role, and research area.
- Choose a JPG, PNG, or WebP photo up to 8 MB. The browser crops the center to a 256-pixel square and compresses it before upload.
- Review the preview and choose Save profile. Remove clears the selected photo after you save.
- Open Preferences from the avatar menu to choose the default appearance. Save appearance synchronizes it; the header theme control changes this device immediately.
Account navigation
The avatar opens Research profile, Usage & storage, Billing & plans, Your computer, Preferences, and Account guide. Each destination opens a separate page. Account pages do not have article previous/next controls.
Use the sidebar button beside its section title to collapse the desktop sidebar to icons. Your choice is remembered on this browser. On mobile the button opens a navigation drawer; Escape, the close button, or the backdrop closes it. The account menu also supports arrow keys, Home, End, and Escape.
Set a sign-in username
- Create an account with email and confirm that email first.
- Open Research profile from the avatar menu. Your display name can include spaces and does not need to be unique.
- In Username, enter 3–30 characters, starting with a letter or number. Letters, digits, periods, hyphens, and underscores are supported; reserved names cannot be claimed.
- Choose Save profile. The service checks uniqueness without case sensitivity. If someone else claimed the name, choose another.
- On your next sign-in, enter either this username or your email with the same password. Changing a username immediately retires the old name; it may become available to another account. Password recovery always uses your verified email.
Browse calculation history
Open Usage & storage and scroll to Recent calculations. Six records appear on each page, ordered by creation time, newest first. Each row includes its creation date and local time, calculation type, destination, allocated cores and RAM, and recorded status.
Next and Previous change the calculation table page. The resource totals describe your entire account, not just the visible rows. Refresh updates the measurement and current table page. A missing timestamp is shown as unavailable rather than estimated.
Read usage correctly
| Metric | How it is calculated |
|---|---|
| Current cloud files | Current S3 object sizes under your account prefix; excludes old object versions, database metadata, and your local disk. |
| Recorded run time | Sum of completed timing intervals from worker start to completion, including setup and upload overhead. Failed/cancelled runs count when both timestamps exist. |
| Allocated CPU-hours | Recorded run seconds multiplied by allocated cores, divided by 3600. This is allocation, not actual CPU activity. |
| On your computer | Recorded time for runs explicitly targeted to your personal worker. |
| Last 30 days | Recorded duration for runs completed during the preceding 30 days. |
| Unmeasured runs | Historical terminal runs with missing or invalid timing; excluded from duration totals. |
Plan choices and billing
Free provides 10 GiB total cloud storage, structure preparation, private projects, Figure Lab, and DFT and MD simulations on your own connected computer. Early-access accounts can run paid Cloud with verified production Quanta.
Paid Cloud supports all DFT, Guided/manual LAMMPS and OVITO workflows with your selected vCPU and usable RAM. Paid jobs can run in parallel according to funding and regional capacity. Pilot is a separate admin grant with CPU/RAM, operating budget, job count and expiry; old grants default to 2 vCPU, 6 GiB and 15 minutes, with one global slot and no Quanta charge.
Your computer is the default destination for new Free accounts. Connect a worker before running. Changing the destination never migrates an existing run.
Public registration remains waitlist and invitation only. Early-access accounts open Quanta and storage checkout from Billing. Verified production payment refreshes the available balance and compute access; it never starts a job. Institution opens a consultation path.
