Dear Miguel!
MEEP or FDTD in general would indeed benefit much from GPU's.
I tried it once. There was a freeware solution "fastFDTD" using nVidia GPU's.
The speed was incredible high. You gain a factor of 10 in speed very easily.
But the software was completely unstable, full of bugs and no supp
Dear Benjamin!
On our cluster MEEP in 3D with complex fields takes about 1.2 GB per 10^6 mesh
points (this values varies, but you can take it as an estimation).
You have 20 x 6 x 13 x 100^3 = 1560 * 10^6 points
So I would estimate your memory requirements to about 2000GB.
If you don't have acces
We already had this topic. HDF5 output on NFS is very slow. Please find below
the answer from Steven in the thread "[Meep-discuss] HDF5 creating file slow on
NFS (fwd)". We are also using NFS and output is very slow, but so far I had no
time to change the file system, so I cannot tell if another
Dear Steven, dear other MEEP-users!
I followed the discussion with interest about NFS and HDF5 because we have
similar experience.
But what are the alternatives to NFS?
If running meep-mpi on a cluster, every process needs access to the output
directory. So you need to share the directory to al
Dear Nizamov, dear Ben, dear Meep-users!
We are working at Intel quad core xeon processors and I can confirm only little
acceleration when using more than 1 core on the same CPU (20 - 30%).
To my knowledge the limiting factor is not the computational power of the
processors, it's the interface
Dear Steven, dear meep users!
When starting meep-mpi on a distributed computer system, is it possible
to influence which thread starts on which computer?
We are starting several threads per computer and that on several
computers. It would be advantageous if neighboring simulation domains
would
Dear Neal!
We are working on Intel quad-core Xeon processors and it's the same.
The limiting factor is not the computational power of the processors,
it's the interface to the system memory. As in Intel processors all
cores share the same front side bus, execution times decrease very
little wh
Dear Steven, dear Meep users!
I want to "measure" the energy, that is radiated away from a continuous
source with a Gaussian beam shape. So I use the "flux-in-box "
procedure. This is my .ctl-file:
