Provide simple explanation Which of the following statements about data management in OpenCL is FALSE?Select one:a. Data can be transferred from host to device using a write buffer commandb. Host memory and device memory are conceptually separatec. Asynchronous data transfer can be performed using a blocking data transfer commandd. Mapping a memory object allows the host to access the datae. A non-blocking command returns control to the host immediately after the command is calledClear my choiceWhich of the following statements cannot be used to initialise a vector data type?Select one:a. int4 vec = (int4) (1, 2, 3, 4);b. float4 vec (float4) (2.0);c. int4 vec = (int4) ((int2) (5, 10), (int2) (11, 3));d. char4 vec = (char4) ('a', 'c', 'f', 'q');e. float4 vec = array.s01;Clear my choice Which of the following statements related to parallel computing is TRUE?Select one:a. Amdahl's law is concerned with theoretical speedup in parallel computingb. Gustafson-Barsis' law is for serial computing onlyC. Data parallelism and task parallelism cannot be combined to solve a single problemd. In task parallelism, tasks are executed sequentiallye. Synchronisation is not important in task parallelismClear my choiceWhich of the following statements about OpenCL programs is FALSE?Select one:a. An OpenCL program is divided into host and device codeb. OpenCL programs can dynamically discover devices in a systemc. An OpenCL program can have more than one host.d. OpenCL programs speed up applications by offloads computationally intensive code onto devicese. OpenCL programs are coordinated by a hostClear my choiceGiven the following snippet of code:cl::NDRange offset(4);cl::NDRange globalSize(128);cl::NDRange localSize(8);queue.enqueueNDRangeKernel (kernel, offset, globalSize, localSize);Which of the following statements is TRUE?Select one:a. get local_size(0) will return values from 0 to 127b. get local_id (0) will return values from 0 to 3c. get_local_id (0) will return values from 0 to 7d. get local_id (0) will return values from 0 to 127e. get local_size(0) will return values from 0 to 7Clear my choice
