Splitting the workload up within the physical machine is something I've been promoting to anyone who will listen (not many) for years. Splitting a job across multiple hosts using something like map-reduce (or just farming out frames on a render farm) is relatively easy.

By comparison, making a a single process use all the parallel threads available to it is a LOT harder. In terms of CPU, the loss from having an abstraction layer has been close enough to zero for years. This means using it as a poor man's SMT has been acceptable. I have had a couple of video processing workloads that I virtualised without telling anyone and they definitely improved - or at least shifted the bottleneck back to the storage (again).

    Chuck now works for Oracle, and is now deeply embroiled in IT infrastructure.

    Previously, he was with VMware for 2 years, and EMC for 18 years before that, most of them great.

    He enjoys speaking to customer and industry audiences about a variety of technology topics, and -- of course -- enjoys blogging.

    Chuck lives in Vero Beach, FL with his wife and four dogs when he's not traveling. In his spare time, Chuck is working on his second career as an aging rock musician.

    Warning: do not ever buy him a drink when there is a piano nearby.

    I try and write something new 1-2 times per week; less if I'm travelling, more if I'm in the office. Hopefully you'll find the frequency about right!
