1	Isolation of Temporary Storage in High Performance Computing via Linux Namespacing Satchwell, Steven Tanner 01 June 2018 (has links) Per job isolation of temporary file storage in High Performance Computing (HPC) environments provide benefits in security, efficiency, and administration. HPC system administrators can use the mount_isolation Slurm task plugin to improve security by isolating temporary files where no isolation previously existed. The mount_isolation plugin also increases efficiency by removing obsolete temporary files immediately after each job terminates. This frees valuable disk space in the HPC environment to be used by other jobs. These two improvements reduce the amount of work system administrators must expend to ensure temporary files are removed in a timely manner.Previous temporary file removal solutions were removal on reboot, manual removal, or removal through a Slurm epilog script. The epilog script was the most effective of these, allowing files to be removed in a timely manner. However, HPC users can have multiple supercomputing jobs running concurrently. Temporary files generated by these concurrent or overlapping jobs are only deleted by the epilog script when all jobs run by that user on the compute node have completed. Even though the user may have only one running job, the temporary directory may still contain temporary files from many previously executed jobs, taking up valuable temporary storage on the compute node. The mount_isolation plugin isolates these temporary files on a per job basis allowing prompt removal of obsolete files regardless of job overlap. bind mounts mount namespaces Slurm supercomputing HPC temporary storage Science and Technology Studies
2	Temporary storing in future car interiors Palmblad, Fredrik January 2018 (has links) This essay reflects a final thesis work of exploring future opportunities of temporary storing in future car interiors. The work is based from user studies and supported by designers of the automotive industry. The exploratorypart focuses on contextual video interviews studying the use of the interior storage space. Categories are created from the studies to investigate several possibilities parallel throughout the work. A category of exible space is chosen to being developed into a nal design proposal. The result is a concept called LVL - A exible surface that o ers di erent use of the same space.

4	Jämförelse av cache-tjänster: WSUS Och LanCache / Comparison of cache services: WSUS and LanCache Shammaa, Mohammad Hamdi, Aldrea, Sumaia January 2023 (has links) Inom nätverkstekniken och datakommunikationen råder idag en tro på tekniken nätverkscache som kan spara data för att senare kunna hämta hem det snabbare. Tekniken har genom åren visat att den effektivt kan skicka den önskade data till sina klienter. Det finns flera cache-tjänster som använder tekniken för Windows-uppdateringar. Bland dessa finns Windows Server Update Services (WSUS) och LanCache. På uppdrag från företaget TNS Gaming AB jämförs dessa tjänster med varandra under examensarbetet. Nätverkscache är ett intressant forskningsområde för framtida kommunikationssystem och nätverk tack vare sina fördelar. Likaså är uppgiften om att jämföra cache-tjänsterna WSUS och LanCache intressant i och med det öppnar upp insikt om vilken tjänst är bättre för företaget eller andra intressenter. Både forskningsområdet och uppgiften är viktiga och intressanta när användare vill effektivisera användningen av internetanslutningen och bespara nätverksresurser. Därmed kan tekniken minska nedladdningstiden. Till det här arbetet besvaras frågor om vilken nätverksprestanda, resursanvändning och administrationstid respektive cache-tjänst har, och vilken cache-tjänst som lämpar sig bättre för företagets behov. I arbetet genomförs experiment, som omfattar tre huvudmättningar, och följs av en enfallstudie. Syftet med arbetet är att med hjälp av experimentets mätningar få en jämförelse mellan WSUS och LanCache. Resultatet av arbetet utgör sedan ett underlag för det framtida lösningsvalet. Resultaten består av två delar. Den första visar att båda cache-tjänsterna bidrar till kortare nedladdningstider. Den andra är att LanCache är bättre än WSUS när det gäller nätverksprestanda och resursanvändning, samt mindre administrationstid jämfört med WSUS. Givet resultat dras slutsatsen att LanCache är cache-tjänsten som är mest lämpad i det här fallet. / In the field of network technology and data communication, there is a current belief in the technology of network caching, which can store data to later retrieve it more quickly. Over the years, this technology has proven its ability to efficiently deliver the desired data to its clients. There are several caching services that utilize this technology for Windows updates, among them are Windows Server Update Services (WSUS) and LanCache. On behalf of the company TNS Gaming AB, these services are compared to each other in this thesis. Network caching is an interesting area of research for future communication systems and networks due to its benefits. Likewise, the task of comparing the cache services WSUS and LanCache is interesting as it provides insights into which service is better suited for the company or other stakeholders. Both the research area and the task are important and intriguing when users seek to streamline the use of their internet connection and conserve network resources. Thus, the technology can reduce download times. For this work, questions about the network performance, resource usage, and administration time of each cache service are answered, as well as which cache service that is better suited to the company's needs. The work involves conducting experiments, including three main measurements, followed by a single case study. The purpose of the work is to compare WSUS and LanCache using the measurements from the experiment. The outcome of the work then forms a basis for future solution choice. The results consist of two parts. The first shows that both cache services contribute to shorter download times. The second is that LanCache outperforms WSUS in terms of network performance and resource usage, and also requires less administration time than WSUS. Given the results, the conclusion is drawn that LanCache is the most suitable caching service in this case.
