HPC Post Assignment

Q 1. OpenMP Program for Get Environment Information - C/C++ Version The master thread queries and prints selected environment information. (Number of processors, Number of threads, Dynamic threads enabled? , Nested parallelism enabled? )

Q2.Write any serial program convert that to openMP, to MPI program.

Q 3. WAP MPI Scatter (Collective Communications) INPUT: sendbuf[4][4] = { {10.0, 20.0, 30.0, 40.0}, {50.0, 60.0, 70.0, 80.0}, {90.0, 100.0, 110.0, 120.0}, {130.0, 140.0, 150.0, 160.0} }

Q4. WAP for matrix multiplication with MPI

Q. 5 Write any program and apply compiler optimization options (-O1, -O2, -O3 ) and note down timings (apply same dataset)

Q. 6) Port MPI-HMMER application on PARAM SHAVAK and compare time with serial and parallel Solution

Q. 7) apply gprof profiling for following code Program: 1 //test_gprof.c #include<stdio.h>

void new_func1(void);

void func1(void) { printf("\n Inside func1 \n"); int i = 0;

for(;i<0xffffffff;i++);
new_func1();

return;

}

static void func2(void) { printf("\n Inside func2 \n"); int i = 0;

for(;i<0xffffffaa;i++);
return;

}

int main(void) { printf("\n Inside main()\n"); int i = 0;

for(;i<0xffffff;i++);
func1();
func2();

return 0;

} Program: 2 //test_gprof_new.c #include<stdio.h>

void new_func1(void) { printf("\n Inside new_func1()\n"); int i = 0;

for(;i<0xffffffee;i++);

return;

}
