* Mark II Hypercube Maintenance Procedures The Mark II Hypercube Maintenance Procedure bulletin tells the user how to report problems on Mark II. It divides the Mark II maintenance procedure in three sections: * Mark II Software Maintenance * Mark II Hardware Maintenance

* Batch Scheduler Problems

People to contact for assistance in each area are also given,

1. Mark II Software Maintenance

a. Software Additions Jeanne Patterson (JPL x8332) is responsible for the Hypercube User's Manual; hence all new software must be submitted to her with a copy of a mann page. She will contact the person responsible for installing the software.

b. Software Revisions If you have a problem with the Mark II software, supply David Meier (JPL x5062) or Peter Noerdlinger (CIT x6669) with a file containing an example illustrating the problem. They will contact the person who can resolve the problem. Jeanne Patterson will be supplied with information if the change involves a manual revision.

2. Mark II Hardware Maintenance If there appears to be a problem with the cube hardware, the following should be done:

a. If the cube hangs, please type:

/usr/nncp/diag/callsys n > outfile

where n is the dimension of the cube; "outf-ile" is your choice of filename.

b. If the cube sends a global, keep the results from the sysELT call.

c. If the trouble appears to be with the 3 10 IH, please...
