It is still running, so definitely more than a few minutes. Any other<br>
thing that I did wrong?<br>

On a decent system, I'd expect it to finish in a few minutes at most.<br>

Thanks for your reply, Antonio! Yes, I was using NFS before, am<br>
trying on local disk now. BTW, what will a normal time be?<br>

Hi YW,<br>
<br>
Although 8h looks like a very long time to me, it's likely due<br>
to a network filesystem. If that's the case, configuring MPICH<br>
in a local filesystem (e.g. /temp, /tmp, /scratch) should go<br>
back to normal times.<br>

Hi Guys,<br>
<br>
I would like to try out the feature of talking to Intel-MIC<br>
in MPICH2. Therefore I downloaded mpich-3.1 and configured it as<br>
<br>
"./configure --host=x86_64-k1om-linux CC=icc CXX=icpc<br>
F77=ifort FC=ifort CFLAGS=-mmic CXXFLAGS=-mmic<br>
FFLAGS=-mmic FCFLAGS=-mmic LDFLAGS=-mmic"<br>
<br>
<br>
However, it took a very long time (i.e. 8 hours) for me to<br>
finish the configuration. Is it normal? Notice that my system<br>
doesn't have Infiniband but 10GigE connection. However, I<br>
don't think this would affect the configuration time.<br>
<br>
Thanks,<br>
YW<br>
<br>
