You and me both. The funny thing is, I wound up writing a program that would benefit from clustering, and felt my way around setting up MPICH on my zoo. I laughed out loud when I realized that, after all these years, I'd built an impromptu Beowulf cluster, even though the machines are scattered around the house.
Installing MPICH from source instead of from your distribution is best if you can't have all your cluster members running the same version of the same distro and/or have multiple architectures to contend with. But it takes forever to compile, even on a fast machine.
- ilyt 4y agowell since you already have a cluster you could distcc the compilation. I remember doing that on a bunch of machines when we were building gentoo
- dredmorbius 4y agoThat's more a COW, than a (Beo)wulf, no? <https://www.oreilly.com/library/view/high-performance-linux/0596005709/ch01.html https://www.oreilly.com/library/view/high-performance-linux/...> A cluster of workstations (COW) is usually opportunistic exploiting existing systems, and lower density than a dedicated (usually rack-based or datacentre-based) cluster. In practice, COWs usually turn out to be not especially useful, though there are exceptions.
