The ISC High Performance conference brings out the very best in international supercomputing, and this year will be no exception with a host of content focused on HPC in Asia. Singapore has been a hotbed of HPC activity of late, so we caught up with Marek Michalewicz, who was recently named Chief Executive Officer at A*STAR Computational Resource Centre.
“The combination of the ephemeral nature of the cloud and directly addressable archives such as S3 suggest novel methods for using the Lustre HSM interface. Persistent data sets in the cloud need to be managed independently from a ephemeral filesystem and compute resources. Managing datasets in the cloud could, for example, involves importing data from Amazon’s S3 back into a freshly-created Lustre filesystem, performing I/O intensive computations, and then persisting the datasets back to S3 before terminating the filesystem and compute resources. Alternatives for archive formats will also be discussed. AWS S3 will be used for concrete examples, but the general methods should be applicable to other cloud environments as well.”
“Large scale HPC IO is usually done either with a file per process or to a single shared file. Single shared file IO does not scale well in Lustre compared to file per process. This presentation from Cray’s Patrick Farrell will give details, examine the reasons for this, and explore existing and potential solutions. Group locks and a new feature, lock ahead, will be discussed in the context of strided IO.”
“Pleiades, one of the world’s most powerful supercomputers, represents NASA’s state-of-the-art technology for meeting the agency’s supercomputing requirements, enabling NASA scientists and engineers to conduct modeling and simulation for NASA missions. Powered by Lustre, this distributed-memory SGI ICE cluster is connected with InfiniBand in a dual-plane hypercube technology.”
