Scheduler - The scheduler communicates with BOINC clients. Each request includes a description of the host, a list of completed results, and a request for additional work, expressed in terms of the time the work should take to complete. The reply includes a list of results and their corresponding workunits. For each request involves a number of database operations: reading and updating records for the user account and team, the host, and the various workunits and results. Many instances of the scheduler can run at once (it is implemented as a Fast CGI program run from the Apache web server).
(Science) Application - The actual executable that is crunching the results sent to you by the project you are attached to. Science is put in parentheses as not all projects out there do science.
Service Install - An option to install BOINC under Windows. When installed as a service, BOINC can run when no one is logged on. It can also run without the BOINC Manager showing all the time. The graphics will not work natively, while the screen saver shows only textual information. (There is a work around for that). This option needs a Windows administrator account with password.
Shared Memory - From Wikipedia: In computer hardware, shared memory refers to a (typically) large block of random access memory that can be accessed by several different central processing units (CPUs) in a multiple-processor computer system. The issue with shared memory systems is that many CPUs need fast access to memory and will likely cache memory. Whenever one cache is updated with information that may be used by other processors, the change needs to be reflected to the other processors, otherwise the different processors will be working with incoherent data. Such coherence protocols can, when they work well, provide extremely high performance access to shared information between multiple processors. On the other hand they can sometimes become overloaded and become a bottleneck to performance.
Shared User Install - An option to install BOINC, where BOINC runs for whomever logged in.
Short Term Debt - Short-term debt is used by the CPU scheduler. It is adjusted over the set of runnable projects. It is normalized so that minimum short-term debt is zero, and maximum short-term debt is no greater than 86,400 (i.e. one day).
Show Graphics - In BOINC Manager/Tasks, this option is used to open a window with which you can see the graphics of the project, otherwise shown in the screen saver. This only works when the project's application actually has graphics capability/a screen saver built in.
Single User Install - An option to install BOINC, where BOINC will only run for the user who installed it when he is logged in.
Snooze - Stop work (crunching and file transfer) for one hour or until you cancel Snooze.
Status - This shows the condition BOINC is in when doing work, trying to communicate with a project, etc. It's always showing what it is doing.
STD - Abbreviation for Short Term Debt.
Success - Message showing when BOINC has managed to complete communications.
Suspend Project - With this setting in BOINC Manager/Projects, you pause the whole project you selected. It will pause (suspend) all running and waiting results as well. The button will change to the next option you have: Resume.
Suspend Task - With this setting in BOINC Manager/Tasks, you pause individual results. The Button will change to the next option you have: Resume Task.
Suspended - A status message showing you have suspended a project or a task. Another word for suspended is paused.
Suspended by User - A status message showing you have suspended a project or a task.
