CUDA calls outdated

[GFTwrt]

Hello,

I'm using UBUNTU 19.10 (eoan) which uses CUDA10 https://packages.ubuntu.com/source/eoan/nvidia-cuda-toolkit. (GeForce RTX 2070, on Ryzen 7 3800) I can compile newer codes like "fastkick" with CUDA Support. But older codes like "bonsai" needs to be ported to higher "gpu-architecture". Example sapporo_2 sets the flag "-arch=sm_20" which is outdated since CUDA 9 and already set to deprecated in Version 8. Please have look to the build.log attached.

I also tried cython and cython3. The codes where not compiled.

Community codes not built (because of errors):

• bonsai
• bonsai2
• distributed
• etics
• pikachu
• simplex Optional builds failed, need special libraries:
• aarsethzare - cython
• asterisk - java
• athena - cython
• bhtree - cython
• fi - gl, periodic_gl
• gadget2 - cython_periodic, cython_normal, cython_periodic_nogravity, cython_nogravity
• hacs64 - gpu
• hermite - cython
• higpus - gpu
• huayno - cython_cl, cl, cl, cl, cl, cl, cl.so, cl.so, cl.so, cl.so, cl.so, cython, cython_mp, mp.so, mp.so, mp.so
• kepler - cython
• mi6 - gpu
• mosse - cython
• phigrape - gl, grape, gl_gpu
• seba - cython
• smalln - cython
• sse - cython Optional builds failed, need additional python packages:
• tupan

Can you help?

@jbedorf can you have a look at the saporro and bonsai??

Hello, please keep in mind: not just saporro and bonsai have this problem. Other CUDA codes are in the same pit. (Have a look to the attached build.log)

Closing. reopen if necessary. CUDA stuff will need some maintenance; but atm I cannot test this easily..
