- Now Please start to prepare your directories on /work/ollie for transfer to Albedo!
- Delete data you do not need to keep,
- copy tarballs of valuable data to the tape archive (you should do this anyhow, /work has no backup),
- place a copy of data which you need continuously with fast access to /isibhv.
- We will not transfer data automatically from Ollie to Albedo!! This is a chance to clean up ;-)
- until April
NEC investigates if OmniPath is an alternative for Mellanox Infinband as the fast network in Albedo, because Infiniband would be delivered with a large delay - May
Albedo installed at AWI with "slow" Gigabit (10 Gb/s) networkand, if recommended by NEC, fast OmniPath (100 Gb/s) - June / July
Albedo open for power users
Start to copy data from Ollie to Albedo (Note: must be done by yourself, there is no automatic data migration!)
The more Albedo nodes are powered on, the more Ollie nodes have to be switched off. We have no schedule for this, but would decide depending on how useful Albedo already is for how many users. Of course, Albedo has a far better ratio of computing vs. electric power. - AugustJuly
Albedo open for all users - 30. June
Ollie hardware support ends. As a prolongation would cost approx. 200.000€, we keep Ollie running w/o support, but with the option to have basic components (file system, network) repaired in case of an emergency (maintenance on demand). So far, we have very good experiences with the service of MegWare and are confident that we found a solution that is cost efficient and sustainable. - (August Downtime to add Infiniband and - if we decide against OmniPath)
More details
Basically, all hardware is in place at NEC's technical center in Germany except the CPUs (expected end of March) and Mellanox Infiniband cables (expected end of July or even later). Concerning the CPUs, NEC is confident that the date of delivery is met, however, there can always be a bad surprise. For Mellanox, the situation is worse. As Mellanox now belongs to NVIDIA, all customers for NVIDIA's flagship DGX are served first. Therefor, NEC is currently investigating if OmniPath offers similar performance for our benchmarks and for the parallel filesystem GxFS (5PB work/scratch). Depending on the outcome, we would start with OmniPath in April, or with just Gigabit network and with a downtime in August to add Infiniband.
