Hello, As the title of my post suggests, I wanted to ask whether it is possible to combine OpenMP ATOMIC/CRITICAL directives inside an IF... ENDIF

#pragma omp atomic 使用#pragma omp reduction(+:sum)或#pragma omp critical 但是我认为#pragma omp reduction会更好,因为你可以将sum+=Var;添加到里面。 像这样做: x = (i + .5)*step; double z = 4.0/(1.+ x*x); #pragma omp reduction(+:sum) sum += z; - Aizen 这很有帮助。比我之...

Compound database preparation for SBVS The next critical phase of the SBVS process is the creation of compound databases. Small compound databases used in SBVS contain drug-like compounds that are frequently publicly available or may be obtained through purchase or synthesis and have desirable prope...
These studies suggest that the regulation process of the proteolysis from metalloproteases is critical in providing appropriate "start" or "stop" signaling during an inflammatory response [45]. Thus, an anti-inflammatory agent may be the result of TNF light structural changes, which may hamper its...
