AskHL: Semaphores and Interlocks and Shared Memory
Jim asks HoffmanLabs (AskHL) I'm coding in OpenVMS (TM) Alpha Version V7.3-2. I use semaphore in AIX & Linux in order to solve concurrent read/write of share memory(IPC). There's no semaphore function in OpenVMS v7.3-2, Is there any system service can do it??? I also need trigger/block function that like semaphore. Thanks for your reply~

I/O Tips: Spooled Printer Devices?
Spooling a printer or another device? Spooling places a disk in front of an output device in the device I/O path; this to allow sharing a device from several processes, and also to provide asynchronicity in the I/O processing; to disconnect the device processing from the application processing and to speed up the applications. The application output is written first to the disk, the application disconnects, and the data is then released to the target device. Spooling is an old technique, and dates back to how RSX-11 applications accessed printers and similar devices.
AskHL: Memory Channel?
dwz asks HoffmanLabs (AskHL) I'm trying to make a use of a "Compaq Memory Channel HUB 800/8 - CCMHB-AA" ... looking through various memory channel documentation. I'm not clear on what controllers and cables I need to purchase. I would like to ask you for clarification regarding controllers and cabling. The hub itself has got four line cards installed(it has been in use before), with wide SCSI-like connectors. Is it possible to take the two installed cards from the box and put them into an AlphaServer?! I have ES40 and DS20e machines ... providing that I buy the cabling ... or am I mistaken and I need to buy some other type of controller card to install into an AlphaServer?!
