Sending an event from commit handler
by Srivastava, Ankit 21 Jun '17

21 Jun '17

Hi, I have a use case in which I can schedule an event only after I am sure that the previous event will not be rolled back. For this purpose, can I use the commit event handler for sending an event by an LP to itself? Thanks, Ankit --- Ankit Srivastava srivastava4(a)llnl.gov<mailto:[email protected]> +1 925-424-2345 https://asrivast28.github.io

Re: [codes-ross-users] Replay HPL's dumpi trace on CODES

Hi Maxime, Thanks for your message. There seems to be a data type that is either not supported by DUMPI or CODES. Are you familiar with what data types are being used by the HPL trace? I will find out if the support for them can be added in the code.

Unfortunately, I get a lot of "Undefined data type" errors (see the trace below). I have already replayed AMG traces (downloaded here<http://portal.nersc.gov/project/CAL/designforward.htm>) and replayed my own generated AMG traces. It has worked fine. So I'm wondering if I did something wrong, or if it's HPL fault.

Too many rollback events
by Jian Peng 07 Jun '17

07 Jun '17

Hi, My simulation is having too many events rolled back, like 70%. It's still relatively small scale, 16 cores on 4 nodes, using optimistic scheduler. The result is attached. Any general idea of reducing number of rollback events? I used the max-opt-lookahead option and set it to 10000. Is it still a large number? Thanks!
