Follow on Google News | OSU's Network Based Computing Lab Uses DICE Test Bed for Performance Evaluation of Obsidian RoutersAvetec’s DICE program has successfully completed a study on the effectiveness and efficiency of Longbow E100 devices for encrypted data movement between HPC clusters using a file-level data migration tool called ‘dsync.’
By: DICE Program “In this work, we conducted experiments on the DICE program’s geographically dispersed test bed to evaluate the actual performance of Obsidian Longbow Routing on state‐of‐the‐ The research team’s results include findings on how longer latency affects throughput and dsync and also on the effects of enabling encryption. Through the performance evaluation from the Network Based Computing Lab, the team found that using a higher degree of concurrent IO could help achieve better bandwidth utilization and that better throughput is obtained with larger RDMA buffer size and concurrent RDMA streams, since they can pump more data into the data transfer pipeline to attain efficient bandwidth utilization. In the tests run, enabling hardware encryption did not generate a noticeable impact at the measured performance. “Clearly encrypted data movement between HPC clusters is a critical need for the community,” said Al Stutz, co-leader of the DICE program and Avetec’s CIO. “This study allowed the opportunity to put encapsulated InfiniBand products to the test.” To access the performance evaluation report from the Network Based Computing Lab, go to www.diceprogram.org. -30- # # # Avetec's Data Intensive Computing Environment (DICE) program independently evaluates hardware and software solutions for enterprise and government with the goal of helping organizations save critical resources and time. DICE helps organizations in high performance computing and IT focus their resources on technology investments for critical challenges; optimize quality, performance and functionality; End
