We are planning to release IMPSYS 2600 on May 15, 1972, be- tween
- 12 noon and 3 p.m. E.D.T. As discussed at the March 16 seminar held
-
- at BBN, this release constitutes a major change to the IMP program.
-
- Because of the magnitude of the change, the system will be released on
-
- an experimental basis. If problems develop, then the current system,
-
- IMPSYS 2514, will be reloaded and the cutover for IMPSYS 2600 will be
-
- rescheduled for some later time.
-
The actual transfer over to IMPSYS 2600 will require assis- tance
- from site personnel, and we hereby request this assistance. A new
-
- tape of IMPLOD 2600 will be mailed to all sites shortly, and the staff
-
- at BBN will request each site in turn on May 15 to load the new IMPLOD
-
- tape and will detail other procedures to follow thereafter. We prefer
-
- that each site have someone who is familiar with IMP system operation
-
- on hand at this time. At some sites, we may request additional
-
- assistance from the computer operations staffs or programmers in the
-
- case of any problems. We also advise site personnel to refrain from
-
- scheduling produc- tion over the Network during the hours of
-
- switchover, since unforeseen difficulties may arise.
-
It is anticipated that the Hosts will not see any first- order
- effects from the switchover. Leader formats and message types are not
-
- changed. On the other hand, the statistics package has been
-
- extensively modified, and the NMC has been notified of these changes.
-
- The Very Distant Host option will also be included in this new system
-
- release, and it is expected to be activated for use about June 1. The
-
- detailed changes to the IMP system will be described in a forthcoming
-
- revision to BBN Report 1822.
-
Finally, your patience is requested if the new system causes
- unforeseen problems.
