ElectricAccelerator Machine Configuration Tips, Part 1

Due to the nature of Electric Cloud products, we frequently field questions about how to best configure a large number of machines. I'll touch on a few points that we have found particularly interesting, both when helping customers or setting up our own internal machines. (more…)...

Makefile performance: built-in rules

Like any system that has evolved over many years, GNU Make is rife with appendages of questionable utility. One area this is especially noticeable is the collection of built-in rules in gmake. These rules make it possible to do things like compile a C source file to an executable without...

Instead, they said, you should take advantage of increasing CPU density to enable increasing levels of parallelism in your builds — a single system with eight...

How to Set Up Kernel Debugging For Windows in VMWare ESX

You’ll know from my previous blog posts that we have an extensive virtual machine infrastructure here at Electric Cloud (the Continuous Delivery company) to support our build and test process (as many of our customers do). Thought I’d share a neat trick I picked up while rolling out our system....

If you've ever struggled with this problem, you should check out the article. I don't want to spoil the exciting conclusion, but it turns out that the only...

ElectricAccelerator vs distcc - samba reloaded In an earlier post I compared the performance of ElectricAcclerator and distcc by building samba using each tool in turn on the same cluster. In that test I found that Accelerator bested distcc at suitably high levels of parallelism, but that distcc narrowly beat...
