Project filesystem /project
This is a shared - parallel filesystem based on the IBM GPFS software. It is available on all CSCS HPC platforms. Each system can access /project using the native GPFS / NFS client through Infiniband or ethernet.
This filesystem provides intermediate storage space for frequently reused datasets, shared code or configuration scripts, and datasets that need to be accessed from different HPC and analytics platforms. It is also intended for large files. Performance could be increased when using large files, therefore it may be useful to consider taring small files.
Access to /project is granted to all users.
Data and inode quotas are group based. The quota space allocated to each group is 10 TB and 100 000 inodes (both can be modified upon request).
You cannot submit jobs on CSCS HPC systems from /project because of the low performance.
To check your quota usage on /project use this command:
/usr/local/bin/quota.ksh
If this command is not available on the platform your are working on, please email to help(at)cscs.ch.
/project Policy
**
Note that data on /project filesystem is NOT backed up.
You are responsible for making your own copies of essential data on the archive.
**
No Backup
The /project file system is too large to carry out regular backups and therefore a copy of any essential data should also be placed on the archive.
The underlying filesystem and disk infrastructure are designed for redundancy and resilience, but data loss can never be ruled out.
**
For /project filesystem, it is vital that you make a copy of any important data.

Hardware description
Six Transtec servers are serving the gpfs filesystem. Each server has 2 sockets dual core with 8 GB of memory.
The servers are connected to two IBM DS4800 SAN storage through Fiber-channel 4 Gb/s. A total number of 384 disks are connected to both controllers, each disk has 1TB of capacity.
