#mpi

Calling Modern Fortran & MPI fans/lawyers.
What happens if I call MPI_Send / MPI_Recv on a non-contiguous chunk of an array?

I have (where sbuf is a 2D send-buffer array):

MPI_Send(sbuf(ix:ix+nelems-1, :), nelems*ncolumns, ...)

And very similar for receiving. Is this:
legal? bad?

Common mechanisms of cell communication in developing embryos and ears

Every complex organism originates from a single cell that multiplies through countless cell divisions. Researchers #CIDBN & #MPI-DS @thegoecampus, & #Marburg discovered a way that embryonic cells coordinate their behaviour using molecular mechanisms previously only known from the process of hearing: https://www.uni-goettingen.de/en/3240.html?id=7848

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.

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.

Check out Michael Ferguson's new article in the Chapel Blog to learn about how Chapel's design gives it good memory safety properties. The article shows how C, C++, Rust, Python, OpenSHMEM, MPI, and Chapel respond to common programming errors.
