The introduction does not mention failed images. =20 2. There is no explanation of how codes might be written to continue execut= ion in the presence of failed images. 3. I do not understand why SOURCE is required to be a coarray for CO_BROADC= AST but not for the other collectives. 4. The operation defined by OPERATOR of CO_REDUCE should be required to be mathematically associative, because the sequence of partial results to whic= h it is applied is (purposely) undefined. =20 5. There need to be more examples and notes to explain the features. For in= stance, there are no examples of the use of SYNC TEAM.=20 6. The complexity of the whole feature is greater than was envisioned in Ma= rkham. Some reduction would be desirable.=20 John= -- Scanned by iCritical.
