I just wanted to add my last comment since this discussion seems to be very hot! As Jeff mentioned while a process is waiting to receive a message it doesn't really matter if it uses blocking or polling. What I really meant was that blocking can be useful to use CPU cycles to handle other calcul

Do you really mean that Open-MPI uses busy loop in order to handle incomming calls? It seems to be incorrect since spinning is a very bad and inefficient technique for this purpose. Why don't you use blocking and/or signals instead of that? I think the priority of this task is very high because p

Hi Alessandro, As far as I understood , you want to send a row of your two dimensional array using MPI sending functions. This is of course possible in a simple way. You can send/receive data with any type and any size using MPI but you should tell MPI the type your data using MPI_Datatype stru

Hi all, I had posted a message about my problem and I did all solutions but the problem is not solved it. The problem is that I have installed Open-MPI on three machines (1 master+2 slaves). When I submit a job to master I can see that "orted" daemon is launched on all machines (by running "top

No I compiled it myself. I don't know what you mean but I have built it from the file openmpi-1.2.5.tar.gz. Can it be the problem? As I said everything works fine locally. D. Jon Mason skrev: On Tuesday 01 April 2008 04:22:47 pm Danesh Daroui wrote: You mean I should moun
