gaspi_allreduce error: GASPI state vector report all processes healthy

[dhinf]

gaspi_allreduce doesn't affect the state vector in case of an error.
If i use a barrier returning a timeout before allreduce (given example), gaspi_allreduce returns an error. If their is no barrier called before gaspi_allreduce the applications pends forever.
Either way, the state vector doesn't change.

Also, the standard says in case of an error gaspi_allrduce returns GASPI_ERROR not a GPI2 specific error code.

Example:
state_vec_3.cpp.txt

output (8 processes):
2 = 0
3 = 0
4 = 0
5 = 0
6 = 0
7 = 0
0 = 0
time out
0 -> healthy
1 -> healthy
2 -> healthy
3 -> healthy
4 -> healthy
5 -> healthy
6 -> healthy
7 -> healthy
