Abstract
HPC runs in a distributed structure with a single shared pool of data. In our case, the distributed structure is Lustre file system [4], and the single shared pool of data is our declustered HDD RAID (denoted as DCR). To increase performance, it is suggested to use Open CAS technology [3] as a cache on RAM/NVDIMM with special parameters, optimized for heavy data-intensive sequential HPC workload and an online-algorithm which reduces the number of RMW operations, by merging sequential requests into one full-stripe one.
