Question

I couldn't run the code (need help)

Closed this issue 7 years ago · 10 comments

I tried to follow the Readme in order to run the code, but when I try to launch ./src/mpimemu-run, I get the following error

paste.debian.net/1029241/

Best regards.

Edit: Please see latest comment.

For what it is worth, I couldn't reproduce this error on my system (Ubuntu Xenial) using the current mpimemu master head. I did have to install libswitch-perl (sudo apt-get install libswitch-perl), though.

This is a very strange error. Can you please try again in a clean (i.e., new) shell environment?

Oh, I see! You have attached a link to the error (I thought this was the actual error). Silly me.

Okay. Can you please send me the output of the following command:

cat /proc/self/status

I'm working on ubuntu 18.04TLS.

Please find the output of the command through this link.

Thank you.

I think this was the problem (See: 3a8219c).

Can you pull the latest version of the code and try again?

Thank you,

Sam

Thank you, it seems that it goes better but the issue remains.

Please take a look at the output.

Okay, good. I'm glad that problem is now fixed.

May I see the output from the following command:

env | grep MPIMEMU

Answer 7 · 2018-06-15T23:40:11.000Z

I think I see what's happening. It appears as if there is a line break in

MPIMEMU_BIN_PATH: /usr/local/bin/mpimemu

This is causing the mpimemu binary to be run without any arguments and then the following, namely:

-t

is being interpreted as a command.

This is supported by the following output:

# running: mpirun -n 1 /usr/local/bin/mpimemu
 -t 2 -s 10 -w
###
### mpimemu: 1.2-alpha
### date-time: 20180615-113310
### mpi version: 3.1
### numpe: 1
### num nodes: 1
### ppn: 1
### communication workload enabled: no
### samples/second: 10
### sampling duration (seconds): 10

Notice that your runtime arguments are being ignored.

For reference, please see the following expected output.

# running: mpirun -n 1 /home/samuel/devel/mpimemu/src/mpimemu -t 2 -s 10 -w
###
### mpimemu: 1.2-alpha
### date-time: 20180615-174433
### mpi version: 3.1
### numpe: 1
### num nodes: 1
### ppn: 1
### communication workload enabled: yes
### samples/second: 10
### sampling duration (seconds): 2
