HE STATUS OF THE RELEASE OF THE NEW IMP SYSTEM (2600)
We have still not managed to get the new IMP system up.
To recapitulate:
We tried the first time May 15; but, completely under- estimating
- the difficulty of distributing the new system to over twenty-five
-
- sites, we never even got around to debugging the system.
-
We developed a suitable distribution mechanism and tried again
- May 31. This time we got to debug the new IMP system and found a
-
- number of problems which precluded leaving the new system up.
-
Trying again June 6, we got the new IMP system up and working
- quite well, but the version of the TIP system which runs with the new
-
- IMP system wouldn't work hardly at all. So we put the old systems
-
- back up again.
-
The day before yesterday, June 20, we tried again. The IMPs and
- TIPs loaded and seemed to fly quite well, so we left the new systems
-
- up. But by yesterday, June 21, afternoon, with crashes happening in
-
- TIPs at the rate of about one per hour, we backed off again and put
-
- the old systems back up. (One TIP crash per hour in the network means
-
- there is about one crash every eight or ten hours debugging with one
-
- TIP which makes it nasty to debug.)
-
We plan to skip Tuesday, June 27, and Tuesday, July 4, and to try
- again Thursday, July 6 (1972), and if necessary, again on Tuesday,
-
- July 18, and following Tuesdays, as per RFC #343.
