===== Software =====

====== Polyp30 ======
Access to polyp30 is accessible via PBS. Please use an interactive job to (qsub -I) to gain access to its resources. Once you have a job, you can submit your batch job to that node. It has Nvidia Tesla K80 GPGPU. Currently it has in /usr/local the following versions of cuda installed:

<code>user@polyp30:~$ cd /usr/local
user@polyp30:/usr/local$ ls -al |grep cuda
drwxr-sr-x 17 root   staff 4.0K Jun 26  2016 cuda-7.5
drwxr-sr-x  8 root   staff 4.0K Oct 10  2017 cuda-8.0
drwxr-sr-x 19 root   staff 4.0K Mar 26  2018 cuda-9.1
drwxr-sr-x 18 root   staff 4.0K Mar 27  2018 cuda-9.0
drwxr-sr-x 18 root   staff 4.0K Dec 16  2024 cuda-10.2
lrwxrwxrwx  1 root   staff   21 Jul 22 08:06 cuda -> /usr/local/cuda-11.4/
drwxr-sr-x 16 root   staff 4.0K Jul 22 08:08 cuda-11.4</code>

Please update your PATH (echo $PATH) and any other variables to utilize the version you need. (LD_LIBRARY_PATH, PYTHONPATH).

===== K80 GPGPU Support =====
nVidia ended Cuda support for the K80 GPGPU with Cuda 11.4. Newer versions will not function with this GPGPU.

<code>Support for the following compute capabilities are deprecated in the CUDA 11.0 Toolkit:
    sm_35 (Kepler)
    ► sm_37 (Kepler) ◄
    sm_50 (Maxwell)

See matrix link above

===== Hints =====
1. Due to the heavy usage of the login node (polyps / polyp1), it is recommended you launch an interactive job on a compute node. This will provide you the dedicated resources you request rather than running on a shared node.
