I have quantum eapresso it shows error code mpi_abort was invoked on rank 0 in communicator mpi_comm_world with errorcode 1 What this means I'm new in programming stuff How to fix it
one mistake I did was to install/extract pckg in one location(mostly default) and then moving the folders here and there. This might cause an error. Plus delete your older version of Mingw (usually it comes with codeblocks etc). So delete that first before installing this version.
I encountered this error when I put ${workspaceFolder}/** ${MSMPI_INC} on the include path in C/C++ configuration in my project: Cannot find: {project_path}/${MSMPI_INC} Can you help me please? I've followed every step before.
I am not sure why {project_path} variable to the include path. If that still doesnt work, try hard coding the include path (put the value of MSMPI_INC directly in the configurations UI. Hope that helps, and sry for delay
Hi, thanks for your help. Wanted to know how to install a compiler like mpic++. I have g++ from mingw64 but understandably it gives an error mpi.h not defined when compiling.
May he restart the whole process again. Or you might have missed any step in between. You can use only MPI. No need of openmp. You can go with that MSI tools shown in the video along with configurations
1. Restart VS code 2. Restart the whole procedure 3. Update the extensions 4. Check if any env are clashing 5. Put the current using compiler in the highest priority by moving to the top of the list 6. May be a "//" work instead of "/" I am not sure but try these
(MSMPI_INC) variable must be an absolute path to MPI include directory and you have to use the variable directly in VS Code settings rather than like this. Remove D:/MPI/ from the path
I'm getting an error called environment variable msmpi not defined in cmd when I typed set msmpi. I did everything that you said. Even the path is correct. How can I make it work. I'm on Windows 11 Home.
What eco mode does is it disables the dedicated gpu. I'm guessing that's what caused the issue. I switched back to GPU on mode and it started working. And yes, it was showing up in both user and system env variables.
i do the same way as you said but i got an error while include mpi.h file . even the suggestion are shown inside the main function . but while click on Run Build Task it show me this error "cpp:1:10: fatal error: 'mpi.h' file not found"
Open MP for multi thread programming. A normal program in C is a program in single thread. You can also use pragma omp headers to created single threaded programs
Extremely helpful, that you show the right version of the MinGW. Thanks a lot!
HELPFUL VIDEO! YOU SAVE MY LIFE!!!! GREATINGS FROM MEXICO!!!!!

How to fix it
I am sorry, not sure about that tool/software/OS, this video is for windows systems only, as i am downloading MSI packages from microsoft.
Thank you very much! Everything was clear and interesting :-)
Helpful, Thank you so much. It worked.
Thank you very much! I was struggling to make this work but your video helped a lot!

Hi, thanks for your help. Wanted to know how to install a compiler like mpic++. I have g++ from mingw64 but understandably it gives an error mpi.h not defined when compiling.
We install MPI from the Microsoft website (.exe and .msi) as shown in video.
Thanks man
great
I get the error mpi.h: no such file or directory
Do you have any solution? and do i have to install OpenMP? i only want to use MPI

spawn cmd.exe ENOENTBuild finished with error(s). i have this problem how to fix it
I am not sure, Sorry
i did like video until 9:05, when i open my vs code i don't have mpi.c and openmp.c in order to continue. how can i fix it
Those both are files for explaination of video. You can find the github repo link in description.
Thank you man
I am still getting an error
fatal error: mpi.h: No such file or directory
#include
please help me how to resolve it
1. Restart VS code
2. Restart the whole procedure
3. Update the extensions
4. Check if any env are clashing
5. Put the current using compiler in the highest priority by moving to the top of the list
6. May be a "//" work instead of "/"
I am not sure but try these
Some boat as you, I am missing
I find it really helpful. Thank you, brother. Also, can you please upload the source code used in this video?
Yes yes sure.
I will definitely upload within a week from today.
Pushed. You can visit the link in description.
It did not setup the msmpi environment variables for me automatically. What should i be doing?
They won't set automatically. You have to set them in system env variables and then have to use them in VS code C++ settings GUI.
Your video is very helpfull. But, I got error messege “cannot find -lmsmpi”. How can I fix this?
I think you have made capital "i" instead of small "L". Please check it
If not, then may include path in VS code is not properly set
Cannot find: d:/MPI/${MSMPI_INC}
This is the error I am getting, it'll be really helpful if you resolved it
(MSMPI_INC) variable must be an absolute path to MPI include directory and you have to use the variable directly in VS Code settings rather than like this. Remove D:/MPI/ from the path
I am getting an error of no file like MPI.h
There might be some glitches in the process you followed, may be please restart the whole process. Ensure that MPI path is set in both env variables.
I'm getting an error called environment variable msmpi not defined in cmd when I typed set msmpi. I did everything that you said. Even the path is correct. How can I make it work. I'm on Windows 11 Home.
Sorry, am not sure.
May be check in both user and system env variables
What eco mode does is it disables the dedicated gpu. I'm guessing that's what caused the issue. I switched back to GPU on mode and it started working.
And yes, it was showing up in both user and system env variables.
@@rajatkokane5750 oh, but in my case there's no requirement of GPU for this setup. Anyways, good to hear.
i do the same way as you said but i got an error while include mpi.h file . even the suggestion are shown inside the main function . but while click on Run Build Task it show me this error "cpp:1:10: fatal error: 'mpi.h' file not found"
Have you modified the compilation command, which is as "GCC " with all other flags and arguments in the json file ?
I have the same problem, did you fix that?
Or may be env is not set properly
If still the same case, please restart the whole procedure leaving the installation, if poasible

How to run openMP and MPI in C++ code in cmd promit?
You can actually make use of the reference link I referred to run in cmd with flags for both MPI and openMP

Hii, you find the video useful?
Single core run multiple threads and single core single thread send any Codeing
Open MP for multi thread programming. A normal program in C is a program in single thread. You can also use pragma omp headers to created single threaded programs
Most of the programs attached in github are both single and multi threaded. I just made them for showing the time taken by both of them
Nice tutorial. Can I have the sample code used in this video?
Yes definitely! Sorry for being late. I will update description within a week.
Pushed. You can visit the link in description.
Iwant openMP nodes
@@govardhandevil322 as of my knowledge, we have nodes in MPI. These are controlled by MPI commands like MPI_scatter and gather, etc..
It still says mpi.h not found
Just restart the process if possible, there may be some glitches. Check for path (user and system)
did you find the solution @shreyamatade409? please tell
