Issue 8178: Updated fix for ANL ticket 1645,reduces memory usage of that fix

Decrease the new pool limit from
      - 8192K (1024 elements/block x 8192 blocks)
      - 2048K (256 elements/block x 8192 blocks)

Note before ticket 1645 (in V1R1M2) the pool limit was
      - 256K (256 elements/block x 1024 blocks)

So this is an increase over V1R1M2 but a decrease from other (v1.5) MPICH

I intentionally did not increase the elements/block at this time due to an
earlier attempt's effect on gpaw -- an increment of 1024 new communicators
in a pool was much too large.

So although the total pool limit is increased (over V1R1M2) it will still only
grow by 256 elements at a time (same as V1R1M2).

While this limits the maximum pool size, we're unlikely on BGQ to support such
large pools with our memory limitations.

The required construction of the MPID_Sched_t object and the required

A file read was supposed to write the current values into the uninit
variable, but under certain circumstances the read would be 0
bytes, leading to the read call returning 0 and leaving the value

Issue 8879: fix bug in the 'is_local_task' extension.

The extension was reporting a non-zero value when the specified task is
local, but the src/mpid/pamid/src/pt2pt/mpidi_sendmsg.c is expecting a
boolean value to be used in the point-to-point eager limit lookup.

On bgq, the reported value was '64' which caused the eager limit lookup
to go off the end of the array.

The pe 'shift value' is 0 which will result in the expression
(1UL << 0) and should be optimized out by the compiler.

Create a task scaling threshold at which point internal eager is disabled

A new mpidi_platform.h define sets the job size threshold at which
point the default 'internal eager' limits are set to zero. This has the
same effect as specifying the environment variable:


The current threshold for bgq is 512k tasks. The default threshold for
all other platforms is 'max unsigned int" which effectively disables
this threshold check.

This 'disable internal eager' threshold check is done before any

Add 'PAMID_PT2PT_LIMITS' env var to specify *all* point-to-point limit overrides

The entire point-to-point limit set is determined by three boolean

configuration then the limit is not changed. All eight configuration
values are not required to be specified, although in order to set the

Issue 8497: Fix for distributing aggregators across (unequal) bridge sets.

We can't assume all psets are one size and calculate distance/indices
from that.  We need to loop through the ranks, assigning aggregators.
Issue 8238: Fix bridge rank determination for subcomm's

MPIX_Torus2rank/Rank2torus only applies to commm_world so the previous fix is
not sufficient for arbitrary subcomm's.  We can't use any sort of global rank
to find our bridge nodes.

So switch the Allgather/sort to use the bridge coordinates instead of the bridge
rank.  Use the sorted results to determine everything we need - bridge ranks
(either the 'true' bridge rank or an arbitrary (first found) rank), number of
ranks per bridge (pset), etc.  Also remove some code base on old BGL/BGP
psets/virtual psets that doesn't really make sense now (e.g. you can't simply
divide by the number of ranks per node and assume all ranks per node are in a

Also includes:

Issue 8357: Fix Romio (ad_bg) problem with small 'psets' <= 8 ranks.

We default to 8 aggregators per 'pset' but had sort/assign problems when there
were 8 ranks per 'pset' (or fewer).

Here, a BGQ 'pset' is defined as the set of compute nodes using a bridge node.
BGQ does not actually have pset's in the same way as did BGL/BGP.
