When fnode was spcefied, a problem occurred in the resource map (CPU core and GPU topology) on the batch system. For example, only 21 cores can be used out of 28 physical cores.

We recognize it as a batch system malfunction, being organized with vendor to fix.
(28 Sep.) The vendor also confirmed the problem, and suggested the workaround is being tested.
(29 Sep.) Temporary workaround was implemented at 15:30 on 28th.

T3KI-20170914A 2017/8/1   Because there is a problem with the operation of the reservation function, we are not going to publish.

In Ubuntu16.04,  TSUBAME 3.0 can not be logged-in by SSH key authentication, prompting the error "sign_and_send_pubkey: signing failed: agent refused operation."

It can be resolved by registering keys in advance with the ssh-add command on the terminal.

When starting Ansys Fluent with Cygwin/X, segmentation fault may occur.

Can not start COMSOL propmting an error message, when connecting from macOS sierra 10.12. XQuartz to TSUBAME 3.0.

It is very likely that malfunction due to compatibility with OpenGL of Mac. Please connect with following option. "$ ssh -YC login.t3.gsic.titech.ac.jp -l USER-ID".

Please get a TITECH mail address first. We also will fix the portal to show that.

T3KI-20170824A 2017/8/24  

Modules may not be loaded in the second and subsequent nodes.

We recognize that LD_LIBRARY_PATH can not be handed over the second and the subsequent nodes because of a problem of job scheduler. Please add the -v option to the UGE script which specifies the environment variable, and specify the library required for calculation.
ex: #$ -v LD_LIBRARY_PATH=/apps/t3/sles12sp2/cuda/8.0/lib64

T3KI-20170822A 2017/8/18  

Froze with qrsh.

This is because flow control is enabled in the setting of the terminal, so that specific operation (Ctrl + s) can not be used when operating on the remote host by rsh. Execute the following command before running qrsh.
stty -ixon

T3KI-20170818B 2017/8/18   Jobs exceeding 24 hours can be submitted even if not on reserved nodes.
T3KI-20170818A 2017/8/18 2017/9/14

LAMMPS can not be executed with multiple nodes.

This is a bug in the job scheduler UGE.
(14 Sep) At the beginning of the job script, specify the -v option like below to avoid the bug.

 #$ -v LD_LIBRARY_PATH=/apps/t3/sles12sp2/cuda/8.0/lib.375.66:/apps/t3/sles12sp2/cuda/8.0/lib64
