- Dear netters,
-
- When I'm debugging a parallel C program and want to look at the contents of
- variables on processors other than the first processor, I sometimes get the following
- reply:
-
- can't read from data address 0x2f000000
-
- What could be the problem ?
-
- Configuration:
- Sequent Symmetry
- Number of PE's = 8
- DYNIX V3.1.4 NFS
- Debugger: pdbx
-
- The processes read and write from a shared global memory, which is allocated by
- the first processor before the 'm_fork()'.
- I still can step through my program, but I can't print values.
-
-
- Thanx in advance.
