Hi, AFAIK, there is nothing in the MPI standard related to databases. You'll have to figure out your distributed algorithms to interact with databases using MPI is for communications if that's what you want. On the other hand, we can't tell you how to interact with your database.

This is correct path of my mpich installation dir. So, I don't know, how to install mpich 3.0.4 on Ubuntu. Guide don't help me. I'm shoked)) I try to use MPICH on Windows last 2 months, and in the result I decided use Ubuntu. There are problems. It is very sorrow. You said, that easier way - using the pre-built packages, but I find 1.4.1 version. Is it stable version? May I get help with this version on this discuss forum? And, what about package manager? What is it? How I can use it? 2014/1/6 Wesley Bland <wbland(a)mcs.anl.gov> > You need to change '/home/you/mpich-install/bin' to the path of your mpich > installation that you used in earlier steps. > > The easier way to install on MPICH is to use the built in package manager > or one of the pre-built packages available on the MPICH Downloads page. > > Thanks, > Wesley > > > On Jan 5, 2014, at 11:51 AM, Ярослав Иванов <ivanov.jaroslaw(a)gmail.com> > wrote: > > Hello, Pavan.

For more information I copied some part of my code below: double x_in[1024];/* buffer for random numbers */ int main(int argc,char** argv) { ..... MPI_Init(&argc,&argv); MPI_Comm_size(MPI_COMM_WORLD,&numtasks); MPI_Comm_rank(MPI_COMM_WORLD,&rank); if (rank == 0 && numtasks != 5) { printf("Number of tasks = %d\n",numtasks); printf("Only need 5 tasks - extra will be ignored...\n"); } MPI_Barrier(MPI_COMM_WORLD); /******** Thread 0 ************************************/ if (rank == 0) { printf("task %d has started...\n", rank); dest = 1; /* send message to worker - message tag set to 1. */ /* If return code indicates error quit */ rc = MPI_Send(x_in, 1, MPI_DOUBLE, dest, tag, MPI_COMM_WORLD); if (rc != MPI_SUCCESS) { printf("Send error in task 0!\n"); MPI_Abort(MPI_COMM_WORLD, rc); exit(1);} } . . . . .

It’s not clear what you’re asking for here. Could you provide a very small (not your complete code) code example showing what you’re talking about?

Dear all, I want to send / receive a vector of integer values via mpich in a 5-thread plan but it seems each send function just sending one value, the first one. How can I resolve this problem? can I use loop commands inside a mpi function? thanks, Zahra
