Compute Resources
- In general, the offers are limited to members of I-MATH and their students.
Other UZH members are welcome to contact support@math.uz.ch.
Offers
- For small / ad hoc computations, just start the compute software via the thinlinc environment.
For medium computations, please contact support@math.uzh.ch to ask for the best fitting possibilty and to reserve nodes.
For large computations and professional support please check http://www.s3it.uzh.ch/.

Concept
Access
The compute nodes can be accessed by SSH only from inside I-MATH.
Use thinlinc
matlab, mathematica, maple, R, rstudio: just start the application via menu 'Applications > Science > ...' - you'll automatically redirected to the appropriate compute server.
- For non standard compute software please first log on the compute node via 'ssh', than start the program.
- SSH: Log on 'ssh.math.uzh.ch' and jump to the compute node again via 'ssh'.
Operating System
- Ubuntu LTS (Linux) - all compute servers
- Very very limited software might be installed on some Windows virtual machines.
Storage
If you need more than 1GB disk space, please contact support@math.uzh.ch.
- Remote (NFS)
<1GB disk space: Personal Home directory
>1GB disk space: /compute/<account>
- Local
/export/user/<account>
Programs / Software
- All compute servers use the same applications and versions as installed on the thinlinc terminals.
Please report missing or outdated software or wishes to support@math.uzh.ch.
- There is no Intel C or Fortran Compiler.
- If you need other program versions than the default one: open a terminal, type the program name followed by two 'TAB' presses: this will show all available versions of the specified program.
Parallel computing
- Cluster software
- Not installed / offered at I-MATH.
- Various MPI packages and libs are installed. Compiling and preparation to run programs later on a distributed compute cluster are possible.
- Some programs, like Matlab, offers limited builtin auto parallelization.
All of the compute nodes are shared memory machines. It's reasonable to start as many programs in parallel as long the load is less or qual the number of cores.
Determine the load by using the uptime command inside a terminal. The last three numbers are the average number of jobs (=load) in the run queue over the last 1, 5 and 15 minutes.
$ uptime 15:55:20 up 22 days, 24 min, 1 user, load average: 11.97, 11.73, 11.62
