// Testcase Description:
// Verifies working of following Global Atomic Operations:
// 1. atomicAdd,
// 2. atomicSub,
// 3. atomicMax,
// 4. atomicMin,
// 5. atomicAnd,
// 6. atomicOr, and
// 7. atomicXor
// for INT, UNSIGNED and FLOAT input types.
// Tests consist of following scenarios:
// 1) Uniform input value to atomic operation (i.e. every thread will be
// performing atomic operation with the same value)
// 2) Divergent input value (i.e. every thread with be performing
// atomic operation on different values)
