The paper proposes an approach to create various problem-oriented Web interfaces for the URAN supercom-puter using Linux and Microsoft Windows operating systems. These Web interfaces are based on Microsoft SharePoint 2010 using two external extension modules from the “iLove SharePoint” bundle: Power Web-part and Advanced Workflow Ac-tions. These extensions provide the necessary functionality to run the Windows PowerShell scripts within SharePoint. The SSH.NET library provides the facilities to run the necessary PowerShell cmdlets to interact the systems. Also, this paper pro-vides an example of imitating the MATLAB user interface using the SharePoint Web-parts. This is achieved by implement-ing a Power Web-part that contains the PowerShell script which uses the SharePoint object model to generate the necessary user interface elements. The script performs user input and output processing, invocation of the SLURM resource manage-ment system, producing and transferring of the MATLAB commands. It is recommended to use InfoPath forms and docu-ment libraries to solve complex problems. It is possible to connect the SharePoint worker processes that create computational tasks to SLURM using Advanced Workflow Actions for SharePoint Designer 2010. The interaction between the URAN clus-ter's head node and SharePoint is carried out under the SSH protocol using SSH.NET library. The article also considers some security issues of the proposed solution.
