Hello Ian,
Has anyone else seen these problems, and if so, do you have a workaround? I'm using the standard simfactory optionlist with 512 cores and num-threads = 8.
I have seen these problems with SpEC as well (num-threads=1, about 500 cores). Eg:
[170:c425-501] unexpected disconnect completion event from [26:c407-203] Assertion failed in file ../../dapl_conn_rc.c at line 1174: 0 internal ABORT - process 170
I have no workaround unfortunately.
With SpEC I also saw ever increasing memory consumption when using mvapich (though as far as I could tell from mallinfo there was no sign of memory fragmenting the same way we had it in Carpet recently I think).
Yours, Roland
