Parallelizing loops with InlinedFixedVector

[Sukii]

Hi,

I have a mojo code that I am trying to run in parallel with 10 CPU cores. I have done this with FORTRAN code successfully with OpenMP. Trying to run it with Mojo to compare performance but get these errors:

/home/skv/github/vortex_simulations/free2d/parallel_nvortices.mojo:33:12: error: unexpected token in expression
@parameter(inout vors: InlinedFixedVector[Vortex,NUM_VORTICES])
           ^

Please submit a bug report to https://github.com/modularml/mojo/issues and include the crash backtrace along with all the relevant source codes.

I did:

modular update mojo
mojo -v
mojo 24.1.1 (0ab415f7)

Now with code I get:

/home/skv/github/vortex_simulations/free2d/parallel_nvortices.mojo:86:17: error: cannot pass 'fn(vors = inout InlinedFixedVector[Vortex, 800], dt = SIMD[f16, 1]) capturing -> None' value, parameter expected 'fn(Int, /) capturing -> None'
    parallelize[advance](4,10)
mojo: error: failed to parse the provided Mojo
