Hi there, I must start by saying that I probably don't know the spec perfectly ;-) Having said that, let's go for questions that may be stupid ! Is there in DRMAA something dealing with file transfer (I mean other files than stdin/stdout/stderr). Or is this something that is considered out of the scope of DRMAA. In this case, is there a working group specifically dedicated to this because all my problems are now with data management. It looks that there is no specific support for properties related to number of nodes/CPUS ? Again should I go through non specific job properties? I though this was something common to all DRM ?
