I have often wondered why WCG never had a project to search for macromolecules to control diseases (it may be a modeling software limitation). I believe there is one medicine for HIV that uses macromolecules. Large simulations request high parallelism and high IPC's cpus (Xeon or Opteron) not to have too long wus. Solutions? - Multithreaded wus - Gpu wus There's a special requirement for high parallelism: The nature of the calculations must allow doing a certain percentage of the work in parts that can be done at the same time because each part can be done with no effect from the output of other parts done in parallel with them. For GPU workunits, usually an average of at least 40 parts running in parallel at any time. If this requirement is not met, a GPU version of a workunit can take up to about four times as long as a CPU version. I've studied the CUDA method of parallel programming enough that I might be able to help produce a Windows-only version of the application, for Nvidia GPUs only. I'm looking for online OpenCL classes that should allow me to remove the Nvidia-only restriction. This assumes that the CPU application is in some programming language I've already used, such as C, C++, or Fortran. |

If this requirement is not met, a GPU version of a workunit can take up to about four times as long as a CPU version. When i wrote my post, i think that the "optimization" of the code was implied.  To simulate large protein, for example, researchers use clusters with suited code. This assumes that the CPU application is in some programming language I've already used, such as C, C++, or Fortran. Have you tried OpenMP? [Edit 1 times, last edit by [VENETO] boboviz at Jun 24, 2016 9:36:42 AM] |

Have you tried OpenMP? Not so far. It appears suitable for multicore CPU applications, but not GPU applications, based on what I've seen. |
