UNIX and Macintosh Utilities Renamed
In previous versions of the distributed computing products, the MDCE utilities for UNIX
and Macintosh computers were called by
nodestatus.sh
startjobmanager.sh
stopjobmanager.sh
startworker.sh
stopworker.sh
You can now call these with the following commands:
nodestatus
startjobmanager
stopjobmanager
startworker
stopworker
Note: For UNIX and Macintosh, mdce and mdce_def.sh have not been moved or
renamed.
rand Seeding Unique for Each Task or Lab
The random generator seed is now initialized based on the task ID for distributed jobs, or
the labindex for parallel jobs (including pmode). This ensures that the random numbers
generated for each task or lab are unique within a job.
Compatibility Considerations
In previous versions of the distributed computing products, the rand function would by
default generate the same set of numbers on each worker.
Task ID Property Now Same as labindex
Although you create only one task for a parallel job, the system copies this task for each
worker that runs the job. For example, if a parallel job runs on four workers (labs), the
