Народ, подскажите плз, какие существую програмные платформы для распределенных вычислений (кроме BOINC), где можно найти описание и документацию к ним? предлогаю оставлять сдесь ссылки

ребята, помогите перевести на русский, плз:

Client structure

BOINC on the client is structured into a number of separate applications. These intercommunicate using the BOINC remote procedure call (RPC) mechanism.

These component applications are:

• The program boinc (or boinc.exe) is the core client.
• The core client is a process which:
-Takes care of communications between the client and the server.
-The core client also downloads science applications, provides a unified logging mechanism, makes sure science application binaries are up-to-date, and schedules CPU resources between science applications (if several are installed).
-Although the core client is capable of downloading new science applications, it does not update itself. BOINC's authors felt doing so posed an unacceptable security risk[citation needed], as well as all of the risks that automatic update procedures have in computing.
-On Unix, the core client is generally run as a daemon (or occasionally as a cron job).
-On Windows, BOINC initially was not a Windows service, but an ordinary application. BOINC Client for Windows, Versions 5.2.13 and higher add, during installation, the option of "Service Installation".
-Depending on how the BOINC client software was installed, it can either run in the background like a daemon, or starts when an individual user logs in (and is stopped when the user logs out). The software version management and work-unit handling provided by the core client greatly simplifies the coding of science applications.

• One or several science applications. Science applications perform the core scientific computation. There is a specific science application for each of the distributed computation projects which use the BOINC framework. Science applications use the BOINC daemon to upload and download workunits, and to exchange statistics with the server.
• boincmgr (or boincmgr.exe), a GUI which communicates with the core application using remote procedure calls. By default a core client only allows connections from the same computer, but it can be configured to allow connections from other computers (optionally using password authentication); this mechanism allows one person to manage a farm of BOINC installations from a single workstation. A drawback to the use of RPC mechanisms is that they are often felt to be security risks because they can be the route by which hackers can intrude upon targeted computers (even if it's configured for connections from the same computer).
• The GUI is written using the cross-platform WxWidgets toolkit, providing the same user experience on different platforms. Users can connect to BOINC core clients, can instruct those clients to install new science applications, can monitor the progress of ongoing calculations, and can view the BOINC system message logs.
• The BOINC screensaver. This provides a framework whereby science applications can display graphics in the user's screensaver window. BOINC screensavers are coded using the BOINC graphics API, Open GL, and the GLUT toolkit. Typically BOINC screensavers show animated graphics detailing the work underway, perhaps showing graphs or charts or other data visualisation graphics.
• Some science applications do not provide screensaver functionality (or stop providing screensaver images when they are idle). In this circumstance the screensaver shows a small BOINC logo which bounces around the screen.

A BOINC network is similar to a hacker/spammers botnet. In BOINC's case, however, it is hoped that the software is installed and operated with the consent of the computer's owner.

Since BOINC has features that can render it invisible to the typical user, there is risk that unauthorized and difficult to detect installations may occur. This would aid the accumulation of BOINC-credit points by hobbyists who are competing with others for status within the BOINC-credit subculture.
