How do I reserve a large memory node for interactive use on Taito?

If you need significantly more memory than the 128 GB provided on Taito-shell nodes, please proceed as follows:
Login to Taito: ssh -X taito.csc.fi (-X being optional)
Reserve a node with the memory needed using srun:

srun -n1 -p hugemem --mem=mem_in_MB -ttime --x11=first --pty $SHELL
(-X11 is optional)
for example to reserve 1048576MB for 2 hours with graphical access, issue:
 srun -n1 -p hugemem --mem=1048576 -t02:00:00 --x11=first --pty $SHELL
Note, that --pty $SHELL should be the last option.
