Molecular modelers often face a recurring challenge: running heavy computations on local machines. These simulations, particularly involving molecular dynamics, may require significant computational resources and time. SAMSON’s GROMACS Wizard provides a practical solution by allowing users to perform these demanding steps in the Cloud, offering ease, efficiency, and cost-effectiveness.
Why Compute in the Cloud?
Imagine you are running an NVT Equilibration or a full Production Molecular Dynamics Simulation step. These tasks can quickly overwhelm your local system, especially when handling large molecules or detailed parameters. By leveraging Cloud computing, SAMSON’s GROMACS Wizard allows users to scale computational resources based on their needs, ensuring their workflows remain smooth and uninterrupted.
Steps to a Hassle-Free Cloud Simulation
1. Ensuring Credits Availability
Cloud jobs require computing credits. Start by checking your available credits in SAMSON’s Job Manager or via your SAMSON Connect account online. If you need more credits, you can easily purchase them here.
2. Set Up Your Job
Before starting, ensure your input structure and parameters are defined. For optimal performance, validate your setup by attempting a short local run. If that’s not feasible, you can always use the “Generate inputs” option to catch errors before sending tasks to the Cloud.
3. Choosing Cloud Resources
To start, press the Equilibrate in the cloud / Simulate in the cloud button corresponding to your current simulation stage. You can select the machine type, storage size, and view associated costs. For first-time tests, you might want to choose the machine with 4 vCPUs and no GPU, which is both economical and sufficient for small tests.

4. Submission and Monitoring
After selecting the machine, a security dialog summarizes details like resource cost and remaining credits. Once you confirm, the job is initialized. Using SAMSON’s Job manager, you can track progress and check logs. The tool allows you to sort jobs by their status to manage multiple jobs concurrently.
5. Download Results
Once the computation is complete, you’ll receive a notification. Download your results using the Job Manager’s context menu. You can choose to download specific files or all files collectively, ensuring you have everything needed for analysis.
6. Import Results Back to SAMSON
With the downloaded results, you can seamlessly import trajectory files and other outputs into SAMSON for visualization and further analysis. The GROMACS Wizard simplifies this process with tools dedicated to creating plots, analyzing trajectories, and more.
Efficient Cloud Resource Use
If Cloud storage is no longer needed, consider deleting completed jobs. It optimizes credit usage, as storage costs may apply over time. This can be easily accomplished through the Job Manager.
