In this post, I’ll take a look at some runs of the POV-Ray application available in the GridPilot app store: To import this app, just choose “File → Import application”, navigate to the relevant folder and click “OK”.
This example is special in that it does not depend on any preinstalled software package (runtime environment), but includes a precompiled binary. This binary will of course only for certain run on the system it was compiled on. We compiled on Debian Sarge and Scientific Linux 5 and run on all back-ends: a local virtual machine, GridFactory without virtualization and … Read the rest
Here is a video I put together to demo how to use GridPilot to run computations on a GridFactory cluster:
The demo uses the default input files – which are 12 royalty free music files found on incompetech.com. This can be changed – by right-clicking on the input dataset, “music_files”, and choosing “Import file(s)”. If you’ve already imported the … Read the rest
Given the popularity of the iPhone, an interesting use of a batch system is conversion of movie files from the AVI to the MPG4 format. In this post I’ll explain 3 ways doing this with GridPilot. Which way you prefer will likely depend on the number and size of files you want to convert and the power … Read the rest
To gauge the performance of both GridFactory and virtualization layers in a high-CPU/low-throughput setting, we chose the standard ray-tracing program POV-Ray and a standard benchmarking image, shipped with the program.
The standard image that was rendered.
This example is a fairly naive benchmarking exercise consisting simply in rendering the same image with POV-Ray 20 times. Each POV-Ray job used a … Read the rest
