![]() ![]() ClevCalc, which is very easy and fast to use, allows you to customize our calculator with 15 different color options. Besides the normal four operations, it also offers scientific calculator features such as trigonometric, exponential, and logarithmic functions. This calculator app is among the best calculator apps and it’s free. #Run multiple instances of calctape for androidThe game is a math puzzle and aims to have fun.Īlso Read: The Best Math Solver Apps for Android and iPhone In addition, it offers multiple calculator possibilities under a single application, these are classical calculator, scientific calculator, algebra calculator, graphing calculator, and integration calculator.Īdditionally, in this app, there is a game called “Sumzle”. It makes the solutions more understandable with 2D and 3D graphics. This app is supported by Maple, the world’s most powerful math engine, and provides its users with an easy way to solve math problems, not just a calculator. #Run multiple instances of calctape freehave MPI rank 0 process length1-data and MPI rank 1 process length2-data etc.Maple Calculator: Math Solver app is one of the students’ most preferred free calculator apps. This would also help in applications like yours that have different datasets to distribute. Other ideas are: Start a MPI-application with the same number of processes per rank as there are GPUs and use the same device number as the local rank number. If you don't have enough data of one "batch" you may want the opposite: Multiple process submit work to one GPU. Note: You may need to set the GPUs to exclusive-mode so a GPU can only be used by one process. ![]() This check could involve test-creating a stream due to some bug in CUDA which made the setDevice succeed but all later calls failed as the device was actually in use. There is a better (more automatic) way, which we use in PIConGPU that is run on huge (and different) clusters.īasically: Call cudaGetDeviceCount to get the number of GPUs, iterate over them and call cudaSetDevice to set this as the current device and check, if that worked. ![]() Otherwise you need some form of job scheduler (outside the scope of this question, IMO) to be able to query unused GPUs and "reserve" one before another app tries to do so, in an orderly fashion. So the best advice (IMO) is to manage the GPUs explicitly.
