Re: [HTCondor-users] HTCondor and OS architecture

I see,
what do you mean by âMicrosoft plan to change thatâ? Something like ongoing on the Windows Kernel..?

If I get WINE on Linux and Docker on Windows I might be able to run the Linux compiled jobs on windows nodes (hopefully with Docker) and Windows compiled jobs on Linux nodes (hopefully with WINE), is it something feasible or the entropy will take things over?

Although Microsoft has said they plan to change that â and for running Windows on Linux there is WINE â but HTCondor does not do anything special to make jobs run in a cross-platform way.  It is up to you to specify Requirements so that you jobs will only match machines that the jobs can run on â and to install cross-platform software on your execute nodes if necessary.
