I followed you advice and upgraded Ubuntu server to V 18.04. That didn't solve the problem. To install slurm I used the instructions in the web site: https://github.com//mknoxnv/ubuntu-slurm/blob/master/REEADME.mdEric, I had already installed the latest version of slurm (V17.11.5).

As I said in my original note, this is a very inefficient way to run slurm (https://github.com//mknoxnv/ubuntu-slurm/blob/master/REEADME.md) I suggest that you follow the steps manually the first time. If you find that you have the same problem as me , you can use the script file below to automate the reinstall process. As I said in my original note, this is a very inefficient way to run slurm Here's the reinstall script: # # Script to install slurm from a previously downloaded slurm-17.11.5.tar.bz2 file # Commands taken fro slurm install instructions from: # https://github.com/mknoxnv/ubuntu-slurm/blob/masttart. To speed things up, I have created a bash script to reinstall slurm, starting with the tarball extraction step. This is a very inefficient work-around. Can anyone help me solve the problem of why slurm runs only once and then fails on subsequent starts? I can send copies of conf and log files if requested. Thanks, in advance.

Here's a couple more goodies: I wrote a simple C++ program to test submitting a job to slurm. Here's the pgm listing: (my fie name is slurm-test2.cpp #include <iostream> #include <time.h> #include <stdio.h> using namespace std; int main() { // Get system time prior to the looping time_t rawtime; struct tm * timeinfo; time ( &rawtime ); cout << "Current local time and date is :" <<ctime (&rawtime)<<endl; int j ; long i ; long total_count ; i = 0 ; j = 0 ; total_count = 1 ; while (i <=1000000000) { // while (j <=1000 ) { total_count = total_count + 1 ; // j = j + 1 ; // } i = i + 1 ; } cout << " The value of i is " << i<<endl ; // cout << " The value of j is " << j<<endl ; cout << "The value of total_count is " <<total_count<< endl ; // Get time after looping // time_t rawtime; // struct tm * timeinfo; time ( &rawtime ); cout << "Current local time and date is :" <<ctime (&rawtime)<<endl; return 0; } I would attach the compiled executable but I'm using Mailspring mail client and it doesn't seem to have the ability to add attachments. If you have the gcc compiler installed, here's the command to compile the program. g++ {filenaame.cpp} -o {executable file name} Run the executable from the terminal command line to be sure it compiled OK. To run the sample c++ program in slurm, be sure slurm started ok then run the commands in the following script file of make a copy of it and run the script. I named my script slurm-submit.sh. #!/bin/bash # This script will instruct slurm to run a compiled C++ program called # slurm-test2 in Ken's c++_source folder. The script was listed on web # page http://www.arc.ox.ac.uk/content/slurm-job-scheduler#SLURMcommands # set the number of nodes #SBATCH --nodes=1 # set max wallclock time (1 hour in this case) #SBATCH --time=1:00:00 # set name of job #SBATCH --job-name=test-slurm # mail alert at start, end and abortion of execution #SBATCH --mail-type=ALL # send mail to this address #SBATCH ==mail-user=linux-...@comcast.net # run the application /home/ken/c++_source/slurm-test2 You may have to customize the script for your physical system. The last line points to the executable file. If you need copies of my slurm.conf and slurmdbd.conf, just let me know. I hope all of this helps. It took me a lot of hours to get things working. I still need to solve the big problem of slurm only running once and then requiring a reinstall. Have fun.
