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.

When starting Ansys Fluent with Cygwin/X, segmentation fault may occur.
Please try another combination like PuTTy + Xming.
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".
TSUBAME account can not be created unless the TITECH common mail address has been created.
Please get a TITECH mail address first. We also will fix the portal to show that.
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.
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.
|T3KI-20170818B||2017/8/18||Jobs exceeding 24 hours can be submitted even if not on reserved nodes.|
LAMMPS can not be executed with multiple nodes.
This is a bug in the job scheduler UGE.

(2018/1/11) Although we have reproduces defects in verification environments so far, no concrete solution has been found and resolution time is undecided. (2018/4/5) It was solved at year end maintenance.|
|T3KI-20180201||2017/2/1||2017/2/13||If q_core=2 or more is specified, 4 core can not be assigned properly at each node. q_core=1 is no problem.
qsub, qstat, qdel are fail from 23 Sep. It is the bug of batch scheduler.
Specify your group with the newgrp command as a temporary workaround. Click here for details.
(11/1) It was fixed in today's scheduler version upgrade.
There is a case that the job usage history of the portal differs from those of login node. For example, STATUS may be displayed as "処理中(r)[being processed]" even though it had ended.
