Created page with "The feeder streamlines the scheduler's database access. It maintains a shared-memory segment containing 1) static database tables such as applications and application versions..."

New page

The feeder streamlines the scheduler's database access. It maintains a shared-memory segment containing 1) static database tables such as applications and application versions, and 2) a fixed-size cache of unsent result/workunit pairs. The scheduler finds results that can be sent to a particular client by scanning this memory segment, rather than by accessing the database. A semaphore synchronizes access to the shared-memory segment. To minimize contention for this semaphore, a scheduler can mark a cache entry as 'busy' (and release the semaphore) while it reads the result from the database (to verify that it is still unsent).

File Deleter

The file deleter deletes input and output files when they are no longer needed.

Firewall

A firewall is a logical barrier designed to prevent unauthorized or unwanted communications between sections of a computer network. This can be a hardware firewall (inside the modem, router or bridge) or a software firewall.

FLOP(S)

In computing, FLOPS (or flops) is an acronym meaning FLoating point Operations Per Second. This is used as a measure of a computer's performance, especially in fields of scientific calculations that make heavy use of floating point calculations; similar to instructions per second.

One should speak in the singular of a FLOPS and not of a FLOP, although the latter is frequently encountered. The final S stands for second and does not indicate a plural. Alternatively, the singular FLOP (or flop) is used as an abbreviation for "FLoating-point OPeration", and a flop count is a count of these operations (e.g., required by a given algorithm or computer program). In this context, "flops" is simply the plural rather than a rate.
