Compile-time check for MPI_Init or MPI_Init thread
by Marc-Andre Hermanns 20 Jan '10

20 Jan '10

Hi all, we are currently puzzled about how to check whether to call MPI_Init or MPI_Init_thread in one of our programs. Our performance analyzer scout can be built in different versions: MPI, OpenMP, and hybrid MPI/OpenMP. As the code-base is shared, we have #define statements to separate individual portions of the code. To decide whether to call MPI_Init or MPI_Init_thread at compile time we check the #define set by MPI. However, POE on our Power6 Cluster correctly reports MPI 1, as it does not support spawning and is therefore not MPI 2 compliant, yet MPI_Init_thread would be available, and must be used for the hybrid version. My initial idea is to take 'nm' at configure-time of our tool. Check whether MPI_Init_thread is in the library, and set my own #define. Is there a more elegant solution? How are users supposed to portably detect it? Is it something we can/should fix?

For those of you not yet here in atlanta (some got stranded by weather), we have pretty much given up on the agenda on the web site to accommodate those who aren't here yet (e.g., we didn't have the bwcompat meeting or the hybrid meeting yet). -jms Sent from my PDA. No type good.

Re: [Mpi-forum] ATL to Marriott

See the URL for the location of MARTA station, the station is located west side and inside of the airport, taxi station is too but outside. http://www.airportterminalmaps.com/atlanta-airport-terminal-map.html Do not go out to the parking deck side, no sign to the MARTA station. I lost the way from AA baggage claim, downstiars of the airport. Anyway, the hotel web site says that there is free access internet in the hotel, however there is no free internet access in the hotel rooms. The cost is 12.5 USD per day. https://www.marriott.com/reservation/viewRoomPool.mi?marshaCode=atljw&roomP… Shinji @ the hotel. Jeff Squyres says > We neglected to put this info on the web site -- I just called the hotel and they tell me that the quickest / easiest / cheapest way to get to the hotel from ATL is MARTA (the public train station). Take the yellow line from ATL to the Lennox stop; the hotel is apparently directly across the street from the Lennox station. $2.75 for a one-way ticket; the trip is approximately 30 mins. > > See everyone tomorrow. > >
