First some background: We are in the throws of moving to UNIX (that is to say if we could only be given the time). Here is the present situation. We run suites of operational batch jobs which transfer to each other something like this: A | B---C---D | E---F---G | G These jobs run in batch on (basically) two machines a CDC 830 (NOS) and a Cray XMP (COS). We are moving to a mix of UNIX (all SysV) machines - a CDC 920 (SGI/IRIX) a CDC 4680 (MIPS/EP/IX) and the new supercomputer is to be an HSX SX 3-44 (?). I would like to do the basic thing above but also add a bit more utility. i.e. Right now if job D depends on A B and C even if A B and C are independent of each other we need to run sequentially like this: A--B--C--D Whereas something like this would be preferred: A B C | | | ------- | D Where A B C and D could all be on different machines. All of the boxes will have NFS the HSX and MIPS boxes have NQS but not the SGI box. My question is - Is RPC the way to go with this and should NQS come into it at all. I am open to any advice specific to this or more general in nature. To save bandwidth I thank any all who reply in advance.
