error using test/heatdis example

[denisbertini]

Trying to restart the test/heasdis_file example from a broken state i got the follwing error

ERROR 3830768914477] [/u/dbertini/mpiio/veloc/src/lib/client.cpp:145:route_file] must call checkpoint_begin() first

than the program hangs ... Should one add a call to checkpoint_begin() ? If yes, where exactly ?

[denisbertini]

Adding the missing call removed the ERROR message, but by restart after a kill -C the processes hang and only few process show CPU saturation the others are idle, any idea ?

Please try the master branch.

I tried the master branch ( git command written in the documentation ) and got the same problem. The heatdis_mem seems to work fine but not the heatdis_file example . I tried the new git version as well, but i stop intalling when using chown root command for pdsh. I have no permission for that on the local cluster. Why using this command if i use ssh ?

[bnicolae]

The command from the documentation is for stable releases. The master branch can be obtained using this git command: git clone --single-branch --depth 1 https://github.com/ECP-VeloC/veloc.git <source_dir>

I am not sure I understand what you are saying. The installation of VELOC does not require root. Please try the command above and follow the instructions from the documentation for the following steps. Let us know if you still have any issue.

Using the command you quoted i got the following problem:

Any idea ?

[denisbertini]

I just tried with release tag veloc.1.2 and it works without the missing library/exec. I will keep using the release then.

Glad to hear it works!
