[Swift-devel] using Swift Trunk for pbs/beagle: doesn't scale

[Ketan Maheshwari]

I was trying trunk on beagle today. Seems when I try to scale up the number
of app tasks, it hangs. To be more precise, I found that above a threshold
of 1600 app tasks, the run hangs with following periodic std.outs:

No events in 10s.

Registered futures:
string[] str_roots  Closed, 500 elements, no listeners
int n  Closed, no listeners
int n  Closed, no listeners
int n  Closed, no listeners
int n  Closed, no listeners
int n  Closed, no listeners
int n  Closed, no listeners
int n  Closed, no listeners
int n  Closed, no listeners
int n  Closed, no listeners
int n  Closed, no listeners
int n  Closed, no listeners
int n  Closed, no listeners
int n  Closed, no listeners
int n  Closed, no listeners
int n  Closed, no listeners
----

Waiting threads:
0-2

When, the threshold is <=1600 app tasks, it seems to work. The
SWIFT_MAX_HEAP is 7000MB.
