ABCI Home Page

■ 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, the Linux versions of ABCI_MP are available, thanks to Drs. Yong-Chul Chae and Xiaowei Dong of

ANL and Dr. Jonathan Smith of Lancaster Univ. If you want to use ABCI on Linux, please

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.
