MPI_Win_sync: Used to ensure the completion of copying the local memory to the shared memory
When two processors access a shared memory
segment, they must have some software and hardware synchronization protocol.
In this section, we describe a DSM architecture that supports shared memory
in a multigrain fashion, called a DSMP.
Further out IBM will offer LA ccNUMA as a way of providing conventional shared memory
interface, which is more familiar to developers, on a distributed memory or message passing system, with no special hardware support.
NumaConnect works with AMD Opteron-based servers connecting to HyperTransport and directly addressable, shared memory
can be up to 256TBytes.
The availability of this product allows us to augment our Linux cluster HPC market to address our customer's needs for large shared memory
HPC at a more affordable level than other solutions available.
The demonstrated simulator distributes a model over three Pentium III processors running RT-LAB under QNX--one executing the model at 50 microseconds sampling time and communicating through shared memory
, with a second processor managing NI PXI-6713 analog output and NI6602 timer I/O boards in order to test the controller.
FeffMPI can run on any parallel processing cluster that supports MPI, and these systems can use distributed or shared memory
, or even a mixture of distributed and shared memory
The first release of the appliance will contain an 8-socket UV system utilizing Intel Xeon E7 8890 v2 processors coupled with 6TB of shared memory
that is designed to scale to 32 sockets and 24TB of shared memory
as a single-node system.
Altix UV is expected to provide the ICR with a massively scalable shared memory
system to process its growing data requirements, including hundreds of terabytes of data for biological networks, MRI imaging, mass-spectrometry, phenotyping, genetics and deep-sequencing information across thousands of CPUs.
This single-system image consists of 512 processors attached to shared memory
and an input/output subsystem, all of which are connected by the robust IRIX operating system from SGI.
With a Dolphin Interconnect Solutions SCI switch that DG uses to create ccNUMA distributed shared memory
arrangements a 64-way system costs from $3.
