Which of the following statements about events is/are FALSE?1. A callback function can be triggered when an event completes2. An event object's callback function must be set before associating it with a command3. A user event can be used to abort a command from executing on a deviceSelect one:a.1 and 2b.2 onlyc. 2 and 3d. 1 onlye. 1 and 3Clear my choiceWhat is a characteristic of the map parallel pattern?Select one:a. It is an iterative patternb. A map pattern must use an associative operatorc. Each operation in the map pattern must be independentd. All operations depend on neighbouring datae. Operations in the map pattern are performed in sequenceClear my choice Which of the following statements about the OpenCL platform model is FALSE?Select one:a. Each device can have more than one processing elementb. Each device can have more than one compute unitc. A GPU is an example of a compute deviced. A host is connected to one or more compute devicese. A compute unit can contain only one processing elementClear my choiceWhat does the following snippet of code do?queue.enqueueNDRangeKernel(kernel, offset, globalSize, cl::NullRange, NULL, &ev);queue.finish();cl_ulong t1 = ev.getProfilingInfo();cl_ulong t2 = ev.getProfilingInfo();cl_ulong result = t2 - 11;Select one:a. It computes the amount of time enqueueNDRangeKernel took to executeb. The result is how long enqueueNDRangeKernel remained in the queuec. It computes the amount of time a work-item took to execution timed. The result is how long profiling took to executee. The result is total time for data transferClear my choice

Semaphores: Select all of the following statements that are true. The operations P (Test) and V (Signal) can be interrupted. The operations P (Test) and V (Signal) run in the operating system's user mode. The values of binary semaphores are restricted to 0 and 1. Counting semaphores are used to manage limited resources and the corresponding access to them. Semaphores can be used to synchronize certain operations between processes. When accessing the list of a semaphore, the FIFO principle should be preferred to the LIFO principle.

Instructions: Create a program that simulates a password checker. Use the password that was set in the first part of the program, if the user enters the password correctly it will output Authentication Successful if the user does not answer the password correctly it will say Failed Attempt! Try again Attempt 1 Each failed attempt is recorded. Each time the user fails, output the number of that failed attempt. Enter the password: Failed Attempt! Try again Attempt 1 Enter the password: Failed Attempt! Try again Attempt 2 If the user fails 5 times output: Error! You have exceeded the number of attempts, try again? Y for "yes" or N for "No" The program should allow the user to try and enter the password again. The attempts should reset back to 0.

2) An automated ticket-issuing system sells rail tickets. Users select their destination andinput a credit card and a personal identification number. The rail ticket is issued and theircredit card account charged. When the user presses the start button, a menu display ofpotential destinations is activated, along with a message to the user to select adestination. Once a destination has been selected, users are requested to input theircredit card. Its validity is checked and the user is then requested to input a personalidentifier. When the credit transaction has been validated, the ticket is issued.a) Discover ambiguities or omissions in the above statement of requirements for part ofa ticket-issuing system.
