I made a cluster using CSSH contains 10 machines in a network inclusive the machine that I use (currently opened machine) and the IP addresses are stored in /etc/clusters , after I opened them using:
cssh -M myUser factorizationcluster
cssh opened all of them, and it asked me to enter the password in each prompt. Now I need to run one command in one of them to be the master while the others are slaves... Is it possible and how to perform that ?
I got the following problem when I used this command :
renice -19 1744
I need to change the state of group of processes from sleep (S) to run (R), is there any command to perform this quickly and note that I have their PIDs.
I used this command sftp [email protected] to start session with a remote virtual machine on the cloud and tried to copy files from my local machine to that machine and I used this command : put l1/l2/file.tar.gz /rl1
Unfortunately, I got the following error :
remote open("/rl1"): Permission denied
I need to transfer files to a virtual machines exist on the cloud of my university and I have both Ubuntu and windows installed on my physical machine. Which tools should I use for this purpose?
I need to know how to check if MPI is already installed on my machine, and if not how much time it takes to be installed ?
I need to run a job in several virtual machines exists in a specific cloud and I have the IP address for all of them and I configured the hostname for all of them. How to run a command in a network of virtual machine ? note that the script of this job divides the job into 4 steps to run in parallel since each step needs 2 thread that run in parallel on one machine, now I need to use more than one machine to run the same script in which to let a threads to perform the parallelism using all theses machines by using this command:
./script.py '100 digits number' slaves.hostnames=hostname1,hostname2,hostname3 --slaves 4 --client-threads 2
The above number is number that I need to factor using all these machines to decrease the overall execution time.
