Hello, I'm a new user and have been trying to install the Einstein Toolkit following the instructions at https://nbviewer.jupyter.org/github/nds-org/jupyter-et/blob/master/CactusTut... . (I'm using arch-linux x64)
I was able to follow the procedures and succesfully submitted the "helloworld" simulation job. Listing the simulations I have:
[ianncunha@oppenheimer Cactus]$ ./simfactory/bin/sim list-sim Warning: job status is U helloworld [ACTIVE (FINISHED), restart 0000, job id 6582]
But trying to get the output I get the following error:
/home/ianncunha/simulations/helloworld/SIMFACTORY/exe/cactus_sim: error while loading shared libraries: libcblas.so.3: cannot open shared object file: No such file or directory
After I installed atlas-lapack, I was unable to import numpy due to the same error. I moved a copy of libcblas.so.3 by hand to /usr/lib64 and got numpy working again, but I'm still getting the error in simfactory.
Could anyone help me giving some insight on how to solve this problem?
Thanks, Arthur
Hello Arthur,
I do not use arch myself and we do not regularly test on it so I cannot give a very definitive answer.
But trying to get the output I get the following error:
/home/ianncunha/simulations/helloworld/SIMFACTORY/exe/cactus_sim: error while loading shared libraries: libcblas.so.3: cannot open shared object file: No such file or directory
After I installed atlas-lapack, I was unable to import numpy due to the same error. I moved a copy of libcblas.so.3 by hand to /usr/lib64 and got numpy working again, but I'm still getting the error in simfactory.
The error seems to be in your Cactus executable. Can you please provide the following information:
* the output of ldd exe/cactus_sim * the "ini" file whose name starts like the output of simfactory/bin/sim whoami * the optionlist file mentioned in that ini file (in cfg folder of simfactory/mdb/) * the file configs/sim/OptionList and configs/sim/config-data/make.config.defn * the content of the file configs/sim/bindings/Configuration/Capabilities/make.BLAS.defn * the content of the file configs/sim/bindings/Configuration/Capabilities/make.LAPACK.defn
You can also try and see if you have the pkg-config package installed. If it is not installed then strange things can happen during auto-detection of libraries.
Could anyone help me giving some insight on how to solve this problem?
For some Linux distros (RedHat derivatives in particular) one has to use the "module" command to enable libraries (eg MPI) and on some one has to select a particular alternative (debian based ones, OpenSuSE).
Sometimes one also has to log out and back in after installing packages.
Yours, Roland
