Release 1.4 of MP-MPICH is now ready for download. |
| 11. | Jul | 04 | |
A new Release of mp-mpich is in preparation - stay tuned. |
| 26. | Jun | 02 | |
A patch release of MP-MPICH (version 1.3.0-a) is available on the download page.
All users of SCI-MPICH should upgrade to this version as it contains important
fixes and improved collective operations.
|
| 22. | Apr | 02 | |
Added a new SCI-MPICH related paper and the related presentation about
Exploiting Transparent Remote Memory Access for Non-Contiguous and One-Sided-Communication
from the Workshop for Communication Architecture in Clusters 2002 (CAC '02) to the SCI-MPICH papers section.
|
| 19. | Apr | 02 | |
We have developed a new, highly efficient broadcast technique for SCI-MPICH with
a nearly constant execution time for any number of processes involved.
|
| 04. | Mar | 02 | |
We made a new official release of MP-MPICH with version 1.3.0.
|
| 06. | Feb | 02 | |
Added an interesting paper (study thesis, see papers section)
of Andreas Gäer, a student I tutored, about highly efficient non-contiguous datatype
communication in SCI-MPICH.
|
| 15. | Nov | 01 | |
New tested beta snapshots are available.
The installation of a full-featured compilation should work fine now.
If you do not yet have an account for the beta-releases (but want one),
just drop us a mail
and we'll grant you access.
|
| 12. | Nov | 01 | |
SCI-MPICH offers highly optimized communication functions for non-contiguous
MPI datatypes. This is an unique feature for MPI libraries.
Also, the "what's cooking?" page has been updated
once again. Wow, the meal is nearly complete!
|
| 17. | Oct | 01 | |
The next release of SCI-MPICH will also include optimized reduction operations
for IA-32 platforms. These optimizations increase the performance especially
in conjunction with the fast SCI interconnect, as can be seen from the
comparison charts that we prepared.
|
| 05. | Oct | 01 | |
Some facts regarding new features of SCI-MPICH like true zero-copy, MPI-2 single-sided
communication and efficient transfer of non-contiguous datatypes can be found in a
presentation and a
paper, published
at the
SCI Summer School / SCI Europe 2001 Conference. All these features make use of SCI's
special characteristics of low-latency, high-bandwidth remote memory read and write accesses.
|
| 30. | Aug | 01 | |
SCI-MPICH now delivers more than 225 MB/s MPI buffer-to-buffer bandwith on a low-cost off-the-shelf
cluster, equipped with Dolphin's D330 SCI interconnect.
|
| 26. | Oct | 01 | |
New beta snapshots of SCI-MPICH & SMI are available.
To avoid excessive downloads that we had to observe recently, we had to
password-protect this page again. Anyone who wishs to download from there,
please drop us a mail and
we'll grant you access. BTW, it's the same password that we used before.
|
| 10. | Aug | 01 | |
The "what's cooking?" page has been updated to reflect
the current status, and the new features page describes the
most important features of SCI-MPICH.
|
| 09. | July | 01 | |
I finally arrived to update at least the Pingpong-benchmarks-results to reflect the current state of SCI-MPICH. The other benchmarks will hopefully be done soon.
|
| 04. | July | 01 | |
The next event in the SCI Europe conference series will be helt at Trinity College Dublin,
Oct. 1st-3rd. Look at the official website for more
information. Everyone interested in fast cluster interconnects,
especially SCI, should contribute or participate. This is also true
for the SCI Summer School , a joint event with
the SCI Europe, which will help to get to know the SCI technology - and have a really good time,
judging from last year's event.
|
| 29. | June | 01 | |
A new public beta release of SCI-MPICH (incl. the SMI library) is available;
Download the snapshot and report back.
No critical bugfixes, only some improvements (i.e. better usage of MPI-IO via PVFS).
|
| 18. | May | 01 | |
A new public beta release of SCI-MPICH (incl. the SMI library) is now available which should fix
many (maybe all?) known problems. It has been tested on Linux 2.2 together with the newest Dolphin drivers and D330 boards.Other configurations should work, too. Please download the snapshot and report back.
|
| 18. | Jan | 01 | |
SCI-MPICH can now also be used in a non-polling mode. This means that waiting
for new messages (i.e. calling MPI_Recv() with no matching message available) does not cost
CPU cycles. More information can be found on the non-polling mode page.
|
| 03. | Jan | 01 | |
The "what's cooking?" page has been updated to reflect
the current status.
|
| 22. | Dec | 00 | |
MP-MPICH 1.2.0-a, including the new version 2.1 of SCI-MPICH,
has been released.
First, please read the release notes. Then
you should download and test the new version (go to the download form if you are a new user, or use your bookmark of the download page).
This version of SCI-MPICH has also been tested with the new
Dolphin D330 PCI-SCI adapters
in systems with Supermicro motherboards which offer 64-bit/66MHz PCI. We will soon
publish first performance results for this high-performance, cost-effective cluster platform.
|
| 30. | Oct | 00 | |
All users of SCI-MPICH under Linux which experience performance problems should
disable write-combining for the remote SCI memory area (via the /proc/mtrr
interface). If you don't know how to manage this, mail us and we'll show you.
A new release of MP-MPICH will be available soon, including numerous enhancements
for SCI-MPICH.
|
| 4. | Sep | 00 | |
The paper and the presentation slides of the SCI Europe/Euro-Par 2000 talk
SCI-MPICH - The Second Generation are now available online in the
publications section.
The complete online proceedings of the SCI Europe 2000 will soon be
available on the SCI Europe 2000
web site.
|
| 19. | Jun | 00 | |
Even if you already know SCI, the
SCI Summer School 2000 might help to deepen your understanding. Additionally, many
people from the SCI community will be there, and we'll have time and opportunity to discuss
and even try out our ideas. Hope to see you in Dublin!
|
| 06. | Jun | 00 | |
A "What's cooking?" page is available which
gives you information on ongoing and upcoming development of SCI-MPICH.
|
| 23. | May | 00 | |
SCI-MPICH 2.0 is available. It has been extensively tested on Solaris x86
, and also Windows NT and Linux. Please read the release notes,
download it and test it!
|
| 31. | Mar | 00 | |

Fixed installation problems with the download archives. If you had problems to install
SCI-MPICH/ch_smi from the 1.99d archives, please download the archives again. Sorry.
|
| 30. | Mar | 00 | |
SCI-MPICH 1.99d is available. Please read the release notes,
download it and test it!
|
| 14. | Feb | 00 | |
It seems that the mmap() related problems some Linux-Users have when
running SCI-MIPCH on more than 2 nodes are related to the glibc-Version used.
We have made successful tests of SCI-MPICH for Linux on up to 8 nodes consisting
of out-of-the-box SuSE 6.2 and RedHat 6.1 distributions (only bigphysarea-patch
has been applied).
We will soon release a new pre-2.0 version - hopefully the last one!
|
| 03. | Jan | 00 | |
Yet another release (1.99c - read the release notes)
|
| 30. | Dec | 99 | |
Release 1.99b - minor bugfix of ch_smi. It seems that
only for our local Linux setup, everything runs at least "good". Linux is not Linux, this is becoming a problem.
|
| 28. | Dec | 99 | |
Release 1.99a of SCI-MPICH is available which fixes all known Linux problems.
Download both, the SMI library and the ch_smi device from the download page.
|
| 17. | Dec | 99 | |
Finally, a new SCI-MPICH release. I planned to call it 2.0 since
it is a major rework of the ch_smi device and the SMI library. But since there
are some known problems on the Linux platform, I called it 1.99. Look at the
release notes and
then proceed to the download page to retrieve the new
release. Don't forget to read the new documentation.
|
| 26. | Aug | 99 | |
updated the performance charts for the ch_smi release 1.1
|
| 23. | Aug | 99 | |
Major update of SCI-MPICH (ch_smi release 1.1) featuring:
more performance: bandwidth for large messages up to 74 MB/s
(see figures),
latency down to 6.3us
dynamic configuration: define the memory layout at startup
lots of bug fixes and improvements: out of beta state
improved mpirun-script and startup options
|
| 26. | Jul | 99 | |
First public beta release of SCI-MPICH
