Hi all,
I was wondering if anyone could help. I'm running some code that calls the
same C function (using ccall) over and over on different inputs using pmap.
Launching julia -p N and running the code works great. I've been trying to
use ClusterManagers to get access to more workers, but now the same code
doesn't work, as it can't find the GSL library my C function uses. The path
to GSL is in my LD_LIBRARY_PATH:
exception on 6: ERROR: error compiling findPolicyCPrices: could not load
module /home/me/project/findP.so: libgsl.so.0: cannot open shared object
file: No such file or directory
I've checked that both times the code has the same working directory:
julia> remotecall_fetch(3,run,`pwd`)
>From worker 3: /home/me/project
It seems that the problem is that my worker instances don't know where the
GSL shared library is located. I've tried adding a dlopen before calling
the cluster manager:
dlopen("/home/me/project/gsl/.libs/libgsl.so.0")
using ClusterManagers
....
And the same error happens. Adding it to worker's paths: run(`export
LD_LIBRARY_PATH=...`) does not work either, can't find the variable.
julia> run(`export
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/me/project/gsl/.libs`)
ERROR: LD_LIBRARY_PATH not defined
Can anyone suggest what to do?
Best?
