AzureClusterlessHPC.jl is a package for simplified parallal computing on Azure. AzureClusterlessHPC.jl borrows the syntax of Julia's Distributed Programming package to easily execute parallel Julia workloads in the cloud using Azure Batch. Instead of a parallel Julia session, users create one or multiple worker pools and remotely execute code on them.
AzureClusterlessHPC provides macros that let us define functions on batch workers, similar to how @everywhere works for a parallel Julia session:
# Define a function
@batchdef hello_world(name)
print("Hello $name")
return "Goodbye"
end
We can then either execute this function on our local machine or as a batch job using the @batchexec macro (which is similar to Julia's @spawn macro for parallel Julia sessions):
# Execute function on local machine
out = hello_world("Bob")
# Execute function via Azure Batch
out = @batchexec hello_world("Jane")
Using the pmap function in combination with @batchexec allows us to run a multi-task batch job:
# Execute a multi-task batch job
out = @batchexec pmap(name -> hello_world(name), ["Bob", "Jane"])
To install AzureClusterlessHPC.jl, run the following command from an interactive Julia session (press the ] key and then type the command):
] add AzureClusterlessHPC.jl
Before being able to use AzureClusterlessHPC.jl you need to create a few Azure resources. Follow the instructions here.
