Hi David,
that's correct. A TM is a single process. A slot is just a virtual concept
in the TM process and runs its program slice in multiple threads.
Besides managed memory (which is split into chunks add assigned to slots)
all other resources (CPU, heap, network, disk) are not isolated and free
Hello,
I know this is an older thread, but ...
If some slots are left empty it doesn't necessarily mean that machine
resources are wasted. Some managed memory might be unavailable, but CPU,
heap memory, network, and disk are shared across slots. To the extent there
are multiple operators executin

Hi,
For the situation where a program specify a maximum parallelism (so it is
supposed to use all available task slots) we can have the possibility that one
of the task managers is not registered for various reasons.
In this case the job will fail for not enough free slots to run the job.
