- What worries me more about a mixed architecture VAX/Alpha VMS Cluster is
- how the poor innocent users are going to sort out the confusion between
- VAX and Alpha executables. I assume DEC will provide solutions for system
- logical name tables etc etc for MAVCs, but I bet they wont for the default
- login directories. The particular problem I see is if the user logs in to
- the Alpha node in the Cluster one day, re-compiles and links all his source
- files, then logs in to the VAX node in the Cluster the next day (why should
- he care what architecture he happens to get?) and wonders why he gets
-
- Image file VXCRNA::DISK$C:[JULIAN]COUNTER.EXE;20
- Image is not an OpenVMS Alpha image
-
- Perhaps one could define a LINK symbol in sylogin that, for the Alpha
- node, directs the .EXE file into a subdirectory [.ALPHA_EXE] ? But this is
- messy, and probably not what the user wants. Defining different directory
- trees depending on the node type is no good either, as it defeats one
- advantage of a cluster, which is to share the data. Unless ... there was some
- way of linking the source files together, and keeping the excutables and object
- files separate.
-
- Has anybody got any bright ideas ?
