ifort executes excruciatingly slow

[Redies__Matthias]

I just installed the intel compiler and it is very very slow. If I just execute ifort to get the "you need to provide a file" message, the it takes 30 seconds:

> $ time ifort                                                                                          
ifort: command line error: no files specified; for help type "ifort -help"
ifort  0.00s user 0.01s system 0% cpu 30.046 total

Is this some license checking feature or why is it so slow. I am using the student version.

I cannot comfirm this:

$ time ifort2019
ifort: command line error: no files specified; for help type "ifort -help"

real    0m0.026s
user    0m0.008s
sys    0m0.012s

Maybe the computer you ran this command was overloaded with other jobs?

No it's my desktop and I am doing nothing else. Just to compare:

> $ time gfortran                                                                                                                                                                                     [±develop ●]
gfortran: fatal error: no input files

This may help: https://www.tecmint.com/strace-commands-for-troubleshooting-and-debugging-linux/ . There is a similar utility for tracing library calls, ltrace .

My guess is that it is related to the license check, but 30 seconds is way beyond what I'd expect to see here. Is your license local (installed with serial number) or are you using a networked license server?

[Redies__Matthias]

I used a license number to install it. Is there a way to improve this?

[Steve_Lionel]

I have a faint memory of similar problems caused by a no-longer-used license file or environment variable pointing to a network server that no longer is available. Please do this: After establishing the ifort command environment

setenv INTEL_LMD_DEBUG=1

Then do a test compile. This will display information about its license searches. You can paste the results here, but please edit out references to your serial number.
