\o/ This is great news. This removes major barriers for the Research team's exploratory work and I highly appreciate it. You have our commitment for us to continue moving more and more of the computations to Spark/Hadoop.

Thank you!

Hi everybody,

stat1008 has 512G of RAM now, enjoy :)

Hi everybody,

Next Tuesday (Nov 17th) at 15:00 UTC we'll shutdown stat1008 to finally add the remaining 256G of RAM.

As always, please reach out to us in the task or via IRC (#wikimedia-analytics) for any issue.

Hi everybody,

We ordered new PSUs for stat1008 to get around the extra power consumption, I'll hopefully schedule another maintenance window to add +256G of ram during the next couple of weeks.

Hi again,

stat1008 is back with 256G of RAM (only +128G). We'll work on adding those extra 256G during the next few days, but it might take a bit :(

Hi everybody,

I am sorry if I mislead you before but the RAM expansion was to 512G on each node (stat1005/stat1008), I misremembered what was the agreed value ("Luca gives us false hopes! What a bad person!" Yes I agree 100%, sorry! :)

The work on stat1005 is already done, but stat1008 is having some problems (we don't have enough power in the PSU to fuel the GPU and the extra ram banks). We'll probably have to complete the maintenance during another day, I'll keep you posted.

Hi everybody,

on Monday 5th there will be some downtime of stat1005 and stat1008 (hopefully one hour max in total) to expand their RAM to 1.5TB (!!!!). The maintenance is scheduled to start around 16 CEST.

As always, please let us know if this impacts your work!
