As a sysadmin that supports multiple R users, a post late last year on InsideHPC drew my attention – Parallel framework for statistical analysis package “R”. The creators of the Simple Parallel R INTerface have “designed and built a prototype framework that allows the addition of parallelised functions to R to enable the easy exploitation of HPC systems.” (paper, source code) In other words, a system that lets R users run on a cluster without learning parallel programming.

On SPRINT: A new parallel framework for R
Large Link Dump, 7/16/2008
- VM HA – service console networking, isolation behavior – and other “under the covers stuff” – An overview of how VMware ESX’s High Availability works under the hood – making it much more apparent to me how important file locking is to HA’s functioning. (I’d love to see an overview of how file locking does – or doesn’t – differ on VMFS versus NFS datastores.)
- Why Upgrade? – DanT on what’s new in Sun Grid Engine 6.0 through 6.2.
- Part II: Since NFSv4 is Stateful It Must Be Less Robust, Right? – “Just because CIFS is old and busted, that doesn’t mean NFSv4 is.” Just kidding, that’s not an actual quote. But I think it’s a reasonable summary of the piece.
- HP – Performance-Optimized Data Center – Yet another vendor produces a data center-in-a-box product – which isn’t to say that there isn’t good technology inside of HP’s product. I wonder if container data centers will come down-market to the point where they become a reasonable alternative for new office building construction instead of building a conventional server room. (Seen at Data Center Knowledge.)
- Understanding NIC Utilization in VMware ESX – Scott Lowe comes through again with another practical piece on networking and VMware ESX.
