Re: [HTCondor-users] Scheduler agnostic API

[Brian Bockelman <bbockelm@xxxxxxxxxxx>]

Hi Tiago,

The closest thing I know of is DRMAA:

http://en.wikipedia.org/wiki/DRMAA

I don't think that ever was widely adopted; that said, HTCondor does provide a DRMAA C library.

Hi,

Does anybody knows of any scheduler agnostic API?

I would guess that most people (or a reasonable number) that use a scheduler system only want to have a certain program to process some data. So I was wondering, did anybody ever saw an API that "automagically" converts scheduler directives to a certain scheduler? I am fully aware that it is impossible to use all the functionality of all schedulers simply because they do not overlap.

But I guess that only a basic job could be easily "mapped" to different schedulers:

-> Condor

request_cpus = 1

request_memory = 100

Executable = someExecutable

arguments = someArgument

transfer_input_files = someInputFile

transfer_files = ON_EXIT

-> PBS, Torque

#PBS -l nodes=1:ppn=1,mem=100

someExecutable someArgument

(I guess PBS flavors would also need to bother with the shh copy side of things, but it seems doable)
