I have a similar question about getting data to all workers. Consider the
following code:
'''
addprocs(2)
using pfuncs
#=
@everywhere function showData()
@show(data)
end
=#
function pstep()
@sync begin
for p in workers()
@async begin
remotecall_fetch(p, showData)
end
end
end
end
@everywhere data = myid()
pstep()
'''
If I uncomment the part where the showData() function is defined, it works
as expected. If I put the definition of showData() into the file pfuncs.jl
and import it as in the example above, it does not work.
>From the manual I figure
"using DummyModule causes the module to be loaded on all processes;
however, the module is brought into scope only on the one executing the
statement."
addresses the problem, but does not help me solve it.
I also tried the let block posted by Jameson.
How do I get the same behaviour as with the @everywhere function definition
in the commented block but being able to use modules?
For completeness here is the pfuncs.jl module:
'''
module pfuncs
export showData
function showData()
@show(data)
end
end
'''
