The parts of wiris devoted to compute the calculations are the components called OmegaKernel calculator kernel. As a consequence, often in the task manager appears more than one OmegaKernel.exe. It is possible to open more than one calculator and make calculations with each of them. In the case that the calculations spend a significant amount of time, it might happen that more than one kernel is opened in such a way that each one responds to one of the calculators and, thus, these calculations are performed concurrently. The action of opening the kernels is done quite immediately under Windows NT/2000/XP because the new kernels are always cloned from a seed kernel. On the other hand, under Windows 98/Me, the new kernels may need a fraction of a second when starting. The number of initial kernels (before any calculation is performed) depends on the configuration. If it is activated Delay first kernel load, there is no kernel; otherwise, there will be one. wiris local desktop works both with Microsoft Java Virtual Machine and Sun Java Virtual Machine (version 1.3 or greater) under the operating systems Windows 98/Me/NT and 2000. However, under Windows XP Home or Professional Edition, only works using the Sun Java (version 1.3 or greater) which should be installed separately. The Sun Java could be downloaded from http://www.java.com .
The application wiris local desktop does not work using the Remote Desktop. If the fast user switch is activated in Windows XP Home or Professional Edition and there is more than one Windows session opened, each time that the session is changed, the wiris server related to the current session is disabled and the wiris server of the new active session is activated; this means that the disconnected sessions can not calculate. |
