Analytical storage planning reduces procurement costs
A very useful method is the analytical storage planning based on measurement data. In the following example, the MS Exchangearea of a company was analyzed to determine the required supply power. see attached picture Fig 2: measured values allow a very precise...

continue from the second parallel reduction blog . To get better scalability (increased program performance as the number of threads increases), it is critical to remove the lock in the upc_forall loop. This can be done by accumulating the partial sum...
