[farmshare-discuss] about farm share memory

Per-user memory on the login nodes (rice.stanford.edu<https://web.stanford.edu/group/farmshare/cgi-bin/wiki/index.php/FarmShare_2#rice.stanford.edu>) is limited to 12 GB, assuming there is little or no memory pressure from other users on the same node. If you need more memory you can submit a job; compute nodes in the normal partition have up to 128 GB of memory, and the bigmem partition includes nodes with 768 GB.

The User Guide<https://web.stanford.edu/group/farmshare/cgi-bin/wiki/index.php/User_Guide> (on the FarmShare wiki<https://web.stanford.edu/group/farmshare/cgi-bin/wiki/index.php/Main_Page>) has information on storage<https://web.stanford.edu/group/farmshare/cgi-bin/wiki/index.php/User_Guide#Storage>: each user's home directory has a 48 GB quota, and additional, per-user scratch space is available in /farmshare/user_data.

Hi,

  I am a graduate student in Mechanical Engineering department. Recently I tried to use farmshare to do some calculation using a well established Fortran program.

  I keep running  into the problems of "segmentation error", which I suspect is caused by most variables in the program are defined using "stack" not "heap". This might cause the calculation out of memory after 7000 lines and the error comes out.

  I want to know how much memory could one student access on farmshare? Can I access more memory if it is not enough? Also, how much storage could we access? Thanks.


Best
Yang
