I am building openmpi on a cluster running rocks. When I build using
./configure --with-tm=/share/apps/torque
--prefix=/share/apps/openmpi/intel I receive the warning
configure: WARNING: Unrecognized options: --with-tm,
--enable-ltdl-convenience
After running make and make install, I run ompi-i
Hi - I have compiled vasp 4.6.34 using the Intel fortran compiler 11.1
with openmpi 1.3.3 on a cluster of 104 nodes running Rocks 5.2 with two
quad core opterons connected by a Gbit ethernet. Running in parallel on
one node (8 cores) runs very well, faster than any other cluster I have
run it
I ran a test of tcp using NetPIPE and got throughput of 850 Mb/s at
message sizes of 128 Kb. The latency was 50 us. At message sizes above
1000 Kb, the throughput oscillated wildly between 850 Mb/s and values as
low as 200 Mb/s. This test was done with no other network traffic. I
then ran f
The switch we are using (Dell Powerconnect 6248) has a switching fabric
capacity of 184 Gb/s, which should be more than adequate for the 48
ports. Is this the same as backplane bandwidth?
So is this a problem with the physical switch (we need a better switch)
or with the configuration of the switch (we need to configure the switch
or configure the os to work with the switch)?
