Is it possible to use computers with different motherboards, cpus and network cards in a rocks cluster distribution?



i am trying to build a small cluster computer out of 5 computers using rocks cluster distribution, but i have a minor issue.



The computers i want to use have different motherboards, cpus and network cards because i picked most of them up from a second-hand store (im doing this the super-cheap way and yes the computers all still work perfectly)



The tutorial i read said i should have my compute "nodes" all have the same motherboards, cpus and network cards (here is the tutorial by the way: https://www.wikihow.com/Build-a-Supercomputer), but i dont want to go and buy 10 compute nodes online, and these second-hand computers are the only ones i have to pull this off, so the core of my question is:
Is it possible to use computers with different motherboards, cpus and network cards in a rocks cluster distribution cluster computer?



Thank you.

Hystrix command on request collapser fallback

Clash Royale CLAN TAG #URR8PPP Hystrix command on request collapser fallback I have a scenario where I want to apply hystrix on the fallback (and process one-by-one) of a hystrix request collapser's batch method. The fallback method ( processEntryBatch_fallback ) is invoked. But the hystrix command ( processEntryBackup ) in turn the fallback invokes is not reported (doesn't even appear on dashboard). And the fallback method ( finalFallback ) is not invoked either. I would like to know what am I missing here ? I referred javanica documentation processEntryBatch_fallback processEntryBackup finalFallback @Service public class DummyService private static final Logger log = LoggerFactory.getLogger(DummyService.class); //batch processing method public void processEntry(List<String> msg) //batch processing throw new RuntimeException("Exception while batch processing"); //processing one-by-one @HystrixCommand(fallbackMethod="finalFallback") public ...
