-
- I have extensive experience with UNIX, and a little experience with
- GUARDIAN (Tandem's proprietary OS). I believe that fault tolerant
- applications (that are not PATHWAY applications) have to be programmed
- as such; ie this does not happen by magic - porting a C program from
- a Sparc to a Tandem will not make it fault tolerant.
-
- Although there is certainly an argument for developing generic C programs
- on a UNIX platform, and later porting them to GUARDIAN (Tandem's ANSI C
- is pretty good), I doubt whether it holds when much of the code needs to
- be GUARDIAN specific.

-
- I dont thing GUARDIAN is POSIX compliant until release D00, although
- I could well be wrong.

-
- It may be an idea to look at Tandem's fault tolerant UNIX platforms
- (ie the Integrity S3), which I believe now runs SVR4.
