Blue Lion, by Arca Noae - Developer Interest

Arca Noae needs your help

In order to make the installation of Blue Lion as smooth and intuitive as possible, we need to update and maintain an extensive database of hardware we are likely to encounter during installation and the drivers associated with the various devices installed in current machines.

Luckily, during the installation of eComStation, a file is created: MACHINE.CFG, stored in <boot drive>\ecs\install\rsp. This file contains all of the relevant data we need to update our current database.

We are asking for community assistance to gather as many MACHINE.CFG files as possible. If you have installed eComStation systems, please attach the MACHINE.CFG file from each one to an email (you may attach multiple files to a single email or send separate ones) addressed to hardware-info at arcanoae dot com. This file should not contain any personally identifiable information, but to be sure, please review before attaching.

Many thanks from the Blue Lion Dev Team for your assistance!

Dramatically improve your virtual machine’s network performance

Current VirtualBox recommendations are to use the virtual Intel network cards for guest machines and to configure for bridged networking. Until now, the only choice for OS/2 was the older, IBM-supplied, Intel E1000 driver. The result? Performance just slightly better than the default AMD PCnet-FAST III virtual adapter.

Now, however, there is a choice. Arca Noae subscribers may use the all-new MultiMac Legacy EM driver (MMLEM). This driver is a breakthrough for virtual machines running under VirtualBox, with performance measured at more than twice the throughput of the older driver.

Some comparisons from netio 1.3 across a 1Gbps unmanaged switch, from an OS/2 VM running the latest 32-bit TCP/IP stack to a 64-bit Linux server running on bare metal1:

E1000:

TCP connection established.
Packet size  1k bytes:  15.04 MByte/s Tx,  9168.71 KByte/s Rx.
Packet size  2k bytes:  19.64 MByte/s Tx,  11.99 MByte/s Rx.
Packet size  4k bytes:  22.38 MByte/s Tx,  13.58 MByte/s Rx.
Packet size  8k bytes:  23.72 MByte/s Tx,  17.62 MByte/s Rx.
Packet size 16k bytes:  24.83 MByte/s Tx,  20.62 MByte/s Rx.
Packet size 32k bytes:  19.52 MByte/s Tx,  17.82 MByte/s Rx.
Done.

MMLEM:

TCP connection established.
Packet size  1k bytes:  13.19 MByte/s Tx,  9183.80 KByte/s Rx.
Packet size  2k bytes:  18.65 MByte/s Tx,  12.20 MByte/s Rx.
Packet size  4k bytes:  27.93 MByte/s Tx,  14.98 MByte/s Rx.
Packet size  8k bytes:  39.91 MByte/s Tx,  19.29 MByte/s Rx.
Packet size 16k bytes:  50.39 MByte/s Tx,  22.74 MByte/s Rx.
Packet size 32k bytes:  28.07 MByte/s Tx,  19.19 MByte/s Rx.
Done.

(Note that the falloff between 16 and 32k appears to be an issue within VirtualBox itself, as the same tests, when run against the host machine, actually report an improvement in throughput for the 32k packet size over the 16k one. A 32-bit Linux guest does not show this falloff.)

As you can see, peak transmit throughput, using 16k byte packets, went from 24.83MByte/s (198.64Mbps) to 50.39MByte/s (403.12Mbps). If you are transferring large files across your network to and from your OS/2 VM, this implies a possible reduction in the amount of time it takes for such transfers by more than one half2.

In addition, while the above tests were run using the Intel PRO/1000 MT Desktop (82540EM) virtual network card in the guest, the MMLEM driver also supports the Intel PRO/1000 T Server (82543GC) and Intel PRO/1000 MT Server (82545EM) virtual network card options available in VirtualBox 5.x, either of which may yield even better throughput (the older IBM-supplied driver does not support these server-class cards).

There are other benefits of the Arca Noae Drivers & Software subscription for virtualized users of OS/2, including full shut down and virtual power off of the VM when using Arca Noae’s ACPI PSD. So if you thought there wasn’t much value in subscribing just to run virtual machines, you might want to look again.

  1. Guest machine running eCS 2.1, configured with 2GB RAM, Intel PRO/1000 MT Desktop (82540EM) virtual network card, 32-bit TCP/IP stack, default sockets. Host machine running openSUSE LEAP 42.1 x64, 16GB RAM, single Intel 82567LF-2 onboard network adapter, and default adapter settings. NETIO target (host) machine running openSUSE 13.2 x64, 32GB RAM, dual Broadcom NetXtreme II BCM5708 onboard network adapters, in bonded active backup configuration, with default adapter settings for the physical bond slaves. Switch was Cisco SR2024 (unmanaged 10/100/1000).
  2. Many factors contribute to overall network throughput, including protocol, aggregate traffic, CPU activity, etc. These figures are meant as a guideline and not a guaranty of performance.

Arca Noae at Warpstock Europe 2016

Arca Noae principals David Azarewicz and Lewis Rosenthal will be on hand at this year’s Warpstock Europe event to discuss some of the great offerings from Arca Noae, including latest driver development and the upcoming Blue Lion release.

Expect more details in the coming days, and be sure to visit the event page for general information and the Arca Noae store to register and purchase your tickets.

Still running mature software? Arca Noae can help

There was some news made recently when Orly Airport in Paris, France suffered some apparent downtime of its Windows 3.1-based DECOR system which provides Runway Visual Range (RVR) information to pilots. Tech news media was abuzz with ridicule for any enterprise still running what it termed as such “antiquated” systems (referring to both DECOR and Windows 3.1, and in several instances, referring to Windows XP and “UNIX” as similarly antiquated (see here, here, and here for examples).

Unfortunately, what many of these news outlets don’t understand is that after all of the years in service, it simply may not make economic sense to replace a working system simply because there’s a new OS or application version available (likely with new and unknown flaws and potential pitfalls). Perhaps a newer version of a critical application did away with what is to that customer a must-have feature, or perhaps the application has been orphaned altogether, and nothing else currently available seems to be able to do as efficient a job as what is already in place.

Arca Noae understands the value of these systems. OS/2 still provides “a better DOS than DOS and a better [16-bit] Windows than Windows” due to its preemptive multitasking capabilities and crash protection, so multiple Windows 3.1 and/or DOS sessions may be started and run independently of one another, where a critical application is less likely to be brought down simply because some other application crashed in a different session.

If you have a need to run mature applications on OS/2, Windows 3.1, or DOS, Arca Noae can help extend the life of your investment in those platforms and those applications. Our OS/2 & eCS Drivers and Software package subscription – available now – can assist in running OS/2 or eComStation on newer hardware. Our upcoming OS/2 release, codenamed Blue Lion, is being designed to provide an installable solution to deploy new systems with an updated OS/2, fully capable of handling those mature DOS and Windows 3.1 applications, as well as native OS/2 applications and ported Linux applications on modern hardware or in a virtualized environment.

Perhaps you need expertise in handling such a transition or in maintaining your mature infrastructure. Arca Noae’s experienced engineers and consultants can provide those services, as well, practically anywhere in the world. Need us? Contact us.
