G'day,
If there is a more appropriate list for this then I apologise for targetting
the wrong people.
I have two questions about the internal management of parallelism within the
Hacker's Release (0.29).
1. There are two spark pools (an ADVISORY_POOL and a REQUIRED_POOL). Could
someone explain to me what the two are for? [I thought that all sparks
were advisory and then when sparked into a full thread were stored in
the threads pool (RunnableThreadsHd-RunnableThreadsTl).
2. In a system that executes with priorities, when a new thread starts (either
sparked or otherwise) it will typically `inherit' the priority of its
`parent' thread. (Either for direct use, or as a basis for determining
the priority of the new thread). I am modifying GHC to implement such
a system but cannot find any reference to a parent thread in the TSO of
a thread. I have found the TSO definitions in Threads.lh but cannot
see any `field' that refers to the contextual thread or its/their
priority. Could someone help me by telling me where that information
is stored, or in fact give me some details on the TSO related
code/definitions.
Thanks everyone -- and the more the better. Please send *anything* you think
might be relevant to me. If you need any more information I'll gladly provide
it.

-Julian.
