■ I benchmarked ABCI_MP on
the following three PCs with different numbers of
CPU cores by running a sample file called LEP.abc:
Intel
Core 2 Duo E6600 @2.4GHz: Windows XP: 2GB RAM CPU
time used=21.7s
Intel
Core 2 Quad Q6600 @2.4GHz: Windows XP: 4GB RAM CPU
time used =13.3s
Intel
Core i7 920 @2.67GHz: 64-bit Windows Vista: 3GB RAM CPU time used =5.1s (ABCI_MP 32-bit version)
Intel
Core i7 920 @2.67GHz: 64-bit Windows Vista: 3GB RAM CPU time used =4.6s (ABCI_MP 64-bit version)
Findings:
1.
Performance of ABCI_MP scales almost linearly with the number of CPU cores.
2.
ABCI_MP 64-bit version runs 10% faster than the 32-bit version on 64-bit
Windows Vista.
Running
ABCI_MP 64-bit version on Windows Vista 64-bit and Corei7 looks very promising.
■ Now, GUI for ABCI to PyPi is available and ABCI can
be easily installed on GNU/Linux and Windows,
thanks to Dr. Sergey V. Matsievskiy.
Installation guide is available here.
■
Now, the Linux versions of ABCI_MP are available, thanks to Drs.
Yong-Chul Chae and Xiaowei Dong of
ANL and
Dr. Jonathan Smith of
visit the
installation guide page:
■ Now, the Windows XP 64 bit version of ABCI_MP
is also available. It is here:

ABCI (Azimuthal Beam Cavity Interaction)
is a computer program which solves the Maxwell
equations
directly in the time domain when a bunched beam goes through an axi-symmetric
structure
on or off axis. An arbitrary charge distribution can be defined by the user
(default=Gaussian).
December 2007
ABCI_MP
was updated to version 12.5. This version fixed some small bugs for users who
want to
use a
large amount of meshes. If you do not belong to this category, you may keep
using the version 12.3,
which is
also included in the package.
MOSES (MOde-coupling
Single bunch. instabilities in an Electron Storage ring) is the program to
which computes
complex coherent betatron tune shifts as a function
of the bunch current
for a Gaussian
beam and provides their graphical representation on a printer in TopDrawer format.
