Message matching for tools
by Marc-Andre Hermanns 16 Dec '15

16 Dec '15

Hi all, CC: Tools-WG, Markus Geimer (not on either list) sorry for starting a new thread and being so verbose, but I subscribed just now. I quoted Dan, Jeff, and Jim from the archive as appropriate. First, let me state that we do not want to prevent this assertion in any way. For us as tools provider it is just quite a brain tickler on how to support this in our tool and in general. Dan wrote: >>> [...] The basic problem is that message matching would be >>> non-deterministic and it would be impossible for a tool to show >>> the user which receive operation satisfied which send operation >>> without internally using some sort of sequence number for each >>> send/receive operation. [...] >>> >>> My responses were: >>> 1) the user asked for this behaviour so the tool could simply >>> gracefully give up the linking function and just state the >>> information it knows > Giving up can only be a temporary solution for tools. The user wants to use this advanced feature, thus just saying: "Hey, what you're doing is too sophisticated for us. You are on your own now." is not a viable long-term strategy. >>> 2) the tool could hook all send and receive operations and >>> piggy-back a sequence number into the message header We discussed piggy-backing within the tools group some time in the past, but never came to a satisfying way of how to implement this. If, in the process of reviving the discussion on a piggy-backing interface, we come to a viable solution, it would certainly help with the our issues with message matching in general. Scalasca's problem here is that we need to detect (and partly recreate) the exact order of message matching to have the correct message reach the right receivers. >>> 3) the tool could hook all send and receive operations and >>> serialise them to prevent overtaking This is not an option for me. A "performance tool" should strive to measure as close to the original behavior as possible. Changing communication semantics just to make a tool "work" would have too great of an impact on application behavior. After all, if it would have only little impact, why should the user choose this option in the first place. Jeff wrote: >> Remember that one of the use cases of allow_overtaking is applications that >> have exact matching, in which case allow_overtaking is a way of turning off >> a feature that isn't used, in order to get a high-performing message queue >> implementation. In the exact matching case, tools will have no problem >> matching up sends and recvs. This is true. If the tools can identify this scenario, it could be supported by current tools without significant change. However, as it is not generally forbidden to have inexact matching (right?), it is unclear on how the tools would detect this. What about an additional info key a user can set in this respect: exact_matching => true/false in which the user can state whether it is indeed a scenario of exact matching or not. The tool could check this, and issue a warning. >> If tools cannot handle MPI_THREAD_MULTIPLE already, then I don't really >> care if they can't support this assertion either. Not handling MPI_THREAD_MULTIPLE generally is not carved in stone. ;-) As I said, we (Markus and I) see this as a trigger to come to a viable solution for tools like ours to support either situation. >> And in any case, such tools can just intercept the info operations and >> strip this key if they can't support it. As I wrote above in reply to Dan, stripping options that influence behavior is not a good option. I, personally, would rather bail out than (silently) change messaging semantics. I can't say what Markus' take on this is. Jim wrote: > I don't really see any necessary fix to the proposal. We could add an > advice to users to remind them that they should ensure tools are compatible > with the info keys. And the reverse advice to tools writers that they > should check info keys for compatibility. I would second this idea, while emphasizing the burden to be on the tool to check for this info key (and potentially others) and warn the user of "undersupport".

Meeting reminder: Thursday Dec 17
by Kathryn Mohror 15 Dec '15

15 Dec '15

Hi all, This is a reminder of our regularly scheduled Tools WG meeting Thursday Dec 17 8:00 AM PST, 11:00 AM EST, 5:00 PM CET. The link for the webex is: https://cisco.webex.com/ciscosales/j.php?MTID=m2c3f15fb156cb498d61af2e40e4da 26b And meeting information can be found here: https://github.com/mpiwg-tools/tools-issues/wiki/Meetings Agenda: This week we will be joined by folks who are interested in using the information provided by the MPI Handles Interface we are developing for debuggers. They will provide their "wish list" for the MPI Objects and information about them that they believe will be most useful in debugging their codes. We will discuss how we can potentially support their wish list. Since it's close to the holidays and right after the Forum meeting, I don't have other items on the agenda for this week. Depending on how the Handles discussion goes, this might be a shorter meeting. Hope to talk with you soon!

I accidentally did have the webex scheduled for 9am US Eastern (my normal timezone). When I got the T-5 minute reminder for it on my computer, I realized the timezone mistake, and I changed to US Pacific (which therefore shifted it 3 hours later). So you might have been caught up in time period when I changed it.

Did you just change the time on the webex? Because just as I wanted to join it gave me a weird error and brought me back to the main page. When I wanted to retry, it told me of the different time. Anyway. Now that the meeting starts at 6 pm I will try to get home before it starts.
