Weather forecasting and climate modeling move closer together

However, current research questions, such as those concerning the regional impacts of anthropogenic #ClimateChange, require that the gap between #weather #forecasting and #climate modeling be gradually closed. This is made possible by modern #supercomputers, which can calculate longer time periods with high spatial resolution.

A team of researchers from the #MPI-M, the #DWD, and other partners has taken on this task and is bringing together what belongs together: the #ICON developments for numerical weather prediction and climate applications.

"Our project has benefited greatly from the fact that the components use the same model structure," says Wolfgang Müller, group leader at MPI-M and lead author of the recently published paper presenting first successes of the project.

Roland Potthast, head of the Department of Meteorological Analysis and Modeling at the DWD, highlights the societal relevance of the work: "The developments help us to take an integrated approach to weather and climate and to provide well-coordinated services ranging from high-resolution weather #forecasts to seasonal and decadal climate forecasts."

Glückwunsch an das GönomiX-Team! Wir freuen uns mit #UMG und #MPI-NAT über ein neues Graduiertenkolleg. Ziel ist es, unser Verständnis der Gene und ihrer Funktionen in der Evolution der Tierwelt zu erweitern.

Dafür werden die Forschenden erstmals vergleichbare Daten zur Genregulation von verschiedenen Tiergruppen wie Käfern, Ringelwürmern, Plattwürmern, Schnecken und Quallen sammeln und die Wirkungsweise ausgewählter Gene untersuchen. Dank an #DFG.

I made the new scalable sort routine for the Chapel standard library! Now it's possible to easily sort a distributed array just by calling the standard library 'sort'. It even outperforms the best distributed Chapel sort to date, and it performs competitively with the KaDiS AMS sort written in MPI. There are more details in the release announcement linked below.

@jamesb @0x47df nifty, but I would've expected something like a #Pi0 with #PoE+#Ethernet adaptors...

  • Cuz that'll be able to run #MPI loads.

Die Struktur und der Umfang der im Folgenden präsentierten Ergebnisse sind darüber hinaus ganz wesentlich durch die unerwartet geringe Anzahl belastbarer statistischer Zahlen determiniert.

Grund hierfür ist neben dem schon erwähnten förmlichen Beschluss der IMK, das vorliegende Projekt nicht zu unterstützen,113 eine in Teilen defizitäre behördliche Erfassungspraxis. (mpi) #Überwachung #Überwachungsgesamtrechnung #MPI

A friend of a friend in Cromwell has hosted an MPI fruit fly trap for 16 years without catching anything. Recently the trap captured its first fruit fly (a male), but we've yet to see an announcement from MPI.

Strange that.

Even worse, the MPI person who collected the trap said they've lost funding & will no longer be maintaining the traps, starting later this year.

What a dumb move. The Luxon government seems determined to save money in all the wrong places.

If you have any parallel applications written in Chapel or other MPI+X alternatives, consider submitting to PAW-ATM [(Parallel Applications Workshop, Alternatives to MPI+X)]. The deadline for submissions is July 24th.

Like last year, PAW-ATM has tracks for both full research papers with reproducibility artifacts and user experience abstracts that are shorter and lighter-weight.

Brought together our two #TitanComputers that used to support two different projects to set up a small #MPI / #OpenMP cluster (96 physical cores, 1TB DRAM, 40TB storage). We will probably drop a couple of GPUs inside them later on, but for now, they will support our EMR data analytics on the #CPU
