CCA ICCC WEATHER DEMO

THE WEATHER DEMO ORIGINALLY DEVELOPED FOR THE ICCC SHOW IS NOW GENERALLY AVAILABLE. IT IS A VERY NICE NETWORK DEMO SINCE IT REALLY CAN/DOES RUN ON TWO MACHINES.

THIS DEMO IS TWO INDEPENDENT PROGRAMS. TOGETHER THEY TRY TO ANSWER ENGLISH QUESTIONS ABOUT THE WEATHER. FOR EXAMPLE, 'DID IT RAIN IN BOSTON ON OCTOBER 7?'. THE NATURAL LANGUAGE PROGRAM IS WRITTEN IN LISP. IT IS A MODIFICATION OF A SYSTEM DEVELOPED BY T. WINOGRAD AT MIT. THE OTHER HALF IS A PRIMITIVE DATACOMPUTER. THE DATACOMPUTER PROVIDES NETWORK DATAMANAGEMENT FACILITIES AND WILL INCORPORATE THE TRILLION-BIT UNICON CURRENTLY BEING INSTALLED AT AMES.

THE TWO PROGRAMS COMMUNICATE VIA DATALANGUAGE USING THE NET.

'WEATHER' NOW USES HOST '37' AS THE LOCATION OF THE DATACOMPUTER. THIS FIXES THE OLD 'CCA' NOT IN THE HOST TABLES BUG.

KEEP IN MIND THAT IS AN EVOLVING SYSTEM, WE PLAN TO IMPROVE 'WEATHER' AND THE DATACOMPUTER THAT IT USES, SO THINGS THAT WORK ONE DAY MAY GET BROKEN THE NEXT.

AVAILABILITY

'WEATHER' (THE LISP HALF) IS A REAL MACHINE USER BOTH CPU AND CORE. WE WOULD OBVIOUSLY PREFER THAT YOU RUN IT ON YOUR MACHINE. IF WE ARE REALLY EMPTY (WHICH FREQUENTLY HAPPENS AT 3 AM) FEEL FREE TO RUN IT ON OUR MACHINE. SINCE OUR SYSTEM HAS NO DRUM, AND WEATHER TAKES ALL OF CORE, PLEASE CHECK WITH SOMEBODY AT CCA BEFORE RUNNING WEATHER IF WE ARE DOING ANYTHING AT ALL. IT IS REALLY A MAJOR LOAD ON OUR MACHINE.

SINCE THE DATACOMPUTER IS LESS OF A LOAD, THE SYSTEM WILL BE MORE AVAILABLE IF YOU CAN RUN 'WEATHER' ON YOUR MACHINE. WE WILL TRY TO RUN THE DATACOMPUTER DURING NON-PRIME TIME. IT CAN BE THOUGHT OF AS THE SERVER HALF OF THIS COMBINATION. PRIME TIME HERE IS 1 TO 5 PM EASTERN TIME, BUT THE MORNING IS FREQUENTLY QUITE BUSY TOO. PLEASE DO NOT USE THE DATACOMPUTER DURING THIS TIME. IT WILL SAVE US THE EFFORT OF TURNING IT OFF. CURRENTLY, ONLY ONE USER AT A TIME CAN RUN A LIMITATION OF THE DATACOMPUTER THAT WILL GO AWAY SOMEDAY.

RFC 420 CCA ICCC Weather Demo January 1973

IF YOU WANT TO RUN A DEMO (NOT JUST PLAY AROUND) WE WILL PROBABLY BE ABLE TO COOPERATE. PLEASE CALL TO MAKE ARRANGEMENTS WELL IN ADVANCE. WE STRONGLY RECOMMEND THAT YOU DO NOT TRY TO GIVE AN IMPORTANT DEMO UNLESS YOU HAVE USED BOTH VERSIONS OF THE SYSTEMS THAT WILL BE USED FOR THE DEMO. EVEN WE GET IN TROUBLE WHEN WE FORGET TO REHEARSE THINGS A BIT.

WEDNESDAY MORNING IS SCHEDULED PREVENTIVE MAINTENANCE TIME. OUR MACHINE WILL NOT BE UP BETWWEN 9 AND 12, BUT IT FREQUENTLY IS DOWN PAST NOON.
