Hello,
I am attempting to modify a relatively large code (Quantum Espresso/EPW) and
here I will try to summarize the problem in general terms.
I am using an OPENMPI-compiled fortran 90 code in which, midway through the
code, say 10 points x(3,10) are broadcast across say 4 nodes. The index 3
Hi George and Jeff,
Thank you for taking the time to respond to my query. You did inspire me in the
right direction. Some of the variables involved in the calculation of B were
not broadcast. In addition,
a double do-loop combined with an IF statement was overwriting on the correct
B values. I
I am attempting to install openmpi-1.10.7 on CentOS Linux (7.4.1708) using
GCC-6.4.0.
When compiling, I get the following error:
make[2]: Leaving directory '/home/vaskarpo/bin/openmpi-1.10.7/ompi/mca/pml/ob1'
Making all in mca/pml/ucx
make[2]: Entering directory '/home/vaskarpo/bin/openmpi-1.10
yet, so the nightly snapshots
for the v3.0.x and v3.1.x branches do not yet contain this fix).

ive Open MPI 2.1.1 a try. It should be source compatible with
EPW. Hopefully the behavior is close enough that it should work.
If not, please encourage the EPW developers to upgrade. v3.0.x is the current
stable series; v1.10.x is ancient.

Hi Jeff,
I looked for the 3.0.1 version but I only found the 3.0.0 version available for
download. So I thought it may take a while for the 3.0.1 to become available.

Gilles,
I have submitted that job with --mca io romio314. If it finishes, I will let
you know. It is sitting in Conte’s queue at Purdue.
As to Edgar’s question about the fil
e same data set that you are using? You could upload to a webpage or similar
and just send me the link.
The second question/request, could you rerun your tests one more time, this
time forcing using ompio? e.g. --mca io ompio
Thanks

been fixed.
Does the issue also occur with GNU compilers ?
There used to be an issue with Intel Fortran runtime (short read/write were
silently ignored) and that was also fixed some time ago.

Gilles,
I have not tried compiling the latest openmpi with GCC. I am waiting to see how
the intel version turns out before attempting GCC.
