[OMPI users] Error during ./Configure

[-Gim]

Hey guys,

Did any of you face this issue before while running ./configure?
"checking size of Fortran 77 INTEGER*8... configure: error: Could not
determine size of INTEGER*8"

Thanks,
Gim

I have attached the ./configure.  The error is " configure: error: Could not
determine size of INTEGER*8"

[OMPI users] MPI Gather Query

[-Gim]

Query in MPI :   What mpi_gather does is take the data being sent by the i
th process and places it in i th location in the receive buffer.   Say, I
need to place the sent data in  i*10 th location in the receive buffer?  Is
this possible at all or I have to use sent and recv ?

[OMPI users] Is this an OpenMPI bug?

[-Gim]

I am trying to use the mpi_bcast function in fortran.  I am using
open-mpi-v-1.2.7

Say x is a real variable of size 100. np =100  I try to bcast this to all
the processors.

I use call mpi_bcast(x,np,mpi_real,0,ierr)

When I do this and try to print the value from the resultant processor,
exactly half the values gets broadcast.  In this case, I get 50 correct
values in the resultant processor and rest are junk.  Same happened when i
tried with np=20.. Exactly 10 values gets populated and rest are junk.!!

ps: I am running this in a single processor. ( Just testing purposes ) I run
this with "mpirun -np 4  "

Cheerio,
Gim
