Whamcloud, EMC Collaborate on PLFS and Lustre Integration

From the post:

Whamcloud, a venture-backed company formed from a worldwide network of high-performance computing (HPC) storage industry veterans, today announced it is extending its working relationship with EMC Corporation (NYSE:EMC). The relationship between the two companies began over a year ago and promotes the open source availability of Lustre. Whamcloud and EMC, a fellow member of the OpenSFS consortium, are extending their collaboration for an additional year.

Whamcloud and EMC will continue working together to provide deeper integration between the Parallel Log-structured File System (PLFS) and Lustre. As part of their joint efforts, Whamcloud and EMC will continue augmenting Lustre’s IO functionality, including the enhancement of small file IO and metadata performance. The two companies will look for multiple ways to contribute to the future feature development of Lustre.

PLFS is a parallel IO abstraction layer that rearranges unstructured, concurrent writes by many clients into sequential writes to unique files (N-1 into N-N) to improve the efficiency of the underlying parallel filesystem. PLFS can reduce checkpoint time by up to several orders of magnitude. Lustre is an open source massively parallel file system, generally used for large scale cluster computing. It is found in over 60% of the TOP100 supercomputing sites.

Less important for the business news aspects but more important as a heads up on Lustre and PLFS.

Parallel semantic monogamy is one thing. Parallel semantic heterogeneity is another. Will your name/company be associated with solutions for the later?
