1) Message boards : Number crunching : Validator problem? (Message 240)
Posted 10 Oct 2015 by Mumps [MM]
Excuse me, but all of my linux hosts had either 2 or 4 Gig per core, and only exist to run BOINC WU's. I don't expect it was anything to do with RAM. The work units ran to completion in relatively normal times and produced what looks like valid output results.

It's all about the projects inability to validate Linux work against Windows work, and the choice to not enable Homogeneous Redundancy until the project can get around to fixing the apps. It's been pointed out repeatedly what the difference is between the results, and it seems that should be enough of a clue to fix the problem.

It looks like tasks crunched by both windows and linux will not validate together. Which means if the the third machine is windows, the linux machine loses out. And vice versa. Until this gets resolved, can homogeneous redundancy please be turned on?

FWIW, the only difference here is the 5th line of the stderr. For windows machines:

0,0,0,0,0,0,0,0,0,

For linux machines:

Well, that's enough wasted effort. After 37 linux hosts, with 322 cores, completing 26385 WU's over 6 days and not a single WU validated and not a single credit granted. And not a peep from the Admin of this project regarding the situation.

I guess I'll head off elsewhere and hope things get addressed eventually to make it worth returning with some compute cycles.

Bump. We are wasting many many thousands of tasks


Bump again. Status please?

Bumping yet again. Two days ago I reattached about 2 dozen Linux hosts and still not a single validation against a Windows host. Still seems that Linux has that first line that's not zeroed out when compared to Windows. As an example:
