Q. What is Single Program Multiple Data?
A general style of writing data parallel programs for MIMD computers is SPMD (single program, multiple data) means all processors execute same program however every processor operates on a separate part of problem data. It's easier to program than true MIMD however more flexible than SIMD. Though most parallel computers today are MIMD architecturally they are generally programmed in SPMD style. In this style though there is not any central controller the worker nodes carry on doing basically the same thing at effectively same time. Rather than central copies of control variables stored on control processor of a SIMD computer, control variables (iteration counts and so on) are generally stored in a replicated fashion across MIMD nodes. Every node has its own local copy of these global control variables however each node updates them in an identical way. There are no centrally issued parallel instructions however communications generally occur in well-defined collective phases. These data exchanges happen in a prefixed manner which implicitly or explicitly synchronizes the peer nodes. The condition is something such as an orchestra without a conductor. There is no central control however every particular plays from the same script. The group as a complete stays in lockstep. This loosely synchronous style has a number of similarities to Bulk Synchronous Parallel (BSP) model of computing introduced by theorist Les Valiant in early 1990's. The limited pattern of the collective synchronization is easier to deal with than complex synchronisation problems of a general concurrent programming.
The Throughput graph represents the amount of data in bytes that the Vusers received from the server in a second. When we evaluate this with the transaction response time, we will
Example of Bitwise-AND Operator In the following example, the bitwise-AND operator (&) compares the bits of two integers, nNumA and nNumB: // Example of the bitwise-AND oper
State the advantages Off-the-shelf - tends to be less expensive as development costs can be spread over many users - can be more sophisticated as large sales bring in c
How many TCP connections are in the "Established" state? Contain relevant output. For one of the established TCP connections, what are the IP address and port number at the remote
I think yes...so if 8259 gives interrupt then it will be serviced instantly but since into pin is left hanging the insr bit will never be set...and so whenever any interrupt occurs
Prove the following identities a. A ‾B ‾C‾ + A ‾BC ‾ + AB ‾C ‾ + ABC ‾ = C ‾ b. AB + ABC + A ‾ B + AB ‾C = B + AC Ans. a. LHS = A'B'C' + A'BC' + AB'C' + ABC' =
Draw the schematic circuit of an Analog to Digital converter using Voltage-to Frequency conversion and explain its principle of operation. Draw its relevant Waveforms. Ans:
A logic gate is an electronic circuit that generates a typical output signal which depends on its input signal. Output signal of a gate is a general boolean operation of its input
