A new banchmark of GEMS system:
A dipole antenna is used to evaluate GEMS system. This example shows that GEMS system speeds up not only for the large problems but also for the relatvely small problems. In this benchmmark, the problem size is just 136MB (it is made larger for the test purpose, the actual problem only requires 16.9MB memory and takes less than 1 minute on a single processor), and can get 22 acceleration factor on a 32-core GEMS system.

 GEMS Box |
| |
 
|
| |
We offer our customers a high performance parallel EM simulation system with optimized processors, memory, network, I/O, operating system, parallel environment, cluster management software, and high performance parallel EM simulation software. This is a turnkey system, and does not require IT maintainance. In case, something happens to GEMS sysmte, GEMS software can recover the system automatically..What the customers need is a power outlet and internet outlet.
The hardware in GEMS box is universal system, which can be used to simulate any serial or parallel software packages from third party. |

GEMS PC Cluster System |
| |
|
| |
We offer alternative GEMS turnkey system which is based on regular PCs. GEMS software supports multiple core/CPU processors, hence, one 4-node GEMS PC cluster can be upto 15 times faster than your solo core PC. GEMS PC cluster can be installed with either Windows or Linux operating system. This is a universal hardware, which can be used to run any other serial or parallel software. Compared to servers, the hardware of a GEMS PC cluster can save up to 80 percent of hardware investment. |

GEMS Workstation |
| |
|
| |
We offer GEMS workstation as an alternative turnkey system which is based on the regular workstation. GEMS workstation allows you to speed up the simulation via multiple core processor. GEMS workstation can be easily extended to two nodes without requiring any network device.
For example, you purchased a GEMS workstation, and like to solve the double size problem with two times acceleration, you can simply purchase one more GEMS node, you will double your compute resource for your simulation. |
