The script contains a section that processes a data file and uses the MPI_COMM_RANK routine: /* Load Data */ std::cout << "Loading data..." << std::endl; ThisTask=0; All.ICFormat=1; RestartFlag=1; /* This is actually an MPI routine, so we will need to set up MPI */ NTask=1; /* Gadget2 global */ All.PartAllocFactor=1.0; /* The factor for allocating memory for particle data. */ All.BufferSize = 1024.0; /* The size (in MByte per processor) of a communication buffer. */ if(!

I have found 2 solutions on the net, one which is not totally free (introduces deliberate delays on the function) and another with limited capability on Windows. The latter can only write to a COM port on Windows, not read. I can't look at the code of the first solution since it is compiled into a .dll (makes sense, otherwise people can just edit the delay and not purchase it...) and the second one seems only to use fopen() to open the port and later fwrite() to it

For any "stmt" elements within that "agency" that don't match any other "stmt" elements based on key1, key2 and key3 I need to output them as is. So after transformation the first "agency" node would only have two "stmt" nodes (one summed) and the second "agency" node would be passed as is because the keys don't match. XSLT 1.0 or 2.0 solutions are ok...though

I made a repo on GitHub (the website), downloaded the client, cloned (dragged and dropped the link GitHub gave me basically) it in, moved my project in the clone directory, and I still didn't see the files. So I checked under "Changes", and found my project files. Now it's saying "Could not commit submodules". How do I fix this? Here's a screenshot if anyone needs it: Due to being too long here is the log in its entirety . 回答1: If your project was itself a git repo

Subversion, CVS, Perforce, Mercurial and the like all use Delta Storage systems - they store the differences between one commit and the next. Git does not do this - it stores a snapshot of what all the files in your project look like in this tree structure each time you commit. This is a very important concept to understand when using Git. Yet when I run git show $SHA1ofCommitObject ... commit

I discovered, after two days mind you, that if I type dnvm use default it adds a path to my environment variable so that the command dnx can be found. This persists only for as long as the current window is open. Why isn't the default .net 5 framework automatically added to the PATH environment variable for me? 回答1: In my case dnvm use

Basically it is just a combination of git fetch , which connects to the remote repository and fetches new commits, and git merge (or git rebase ) which incorporates the new commits into your local branch. Because of the two different commands involved the meaning of git pull is not
