 | | Any LDView users with quad-core machine? —Travis Cobbs
|
| | | I'm working on SMP support in LDView, and I'd like to have someone with a machine with 4 CPU cores test it to see if it works properly on machines with more than 2 CPU cores (my CPU is a dual-core). (SMP is symmetric multi processing: multiple CPUs, (...) (17 years ago, 11-Mar-08, to lugnet.cad.dev)

| | | | | (...) Hi Travis, Congratulations on getting SMP working in LDView. If you can run on Solaris, I have an 8 core with 8 hardware thread box in my office I could try things on. Maybe you'll only use 32 given the above algorithm. I have access to a two (...) (17 years ago, 12-Mar-08, to lugnet.cad.dev)

| | | | | | (...) Thanks. (...) Yowza! In theory it will run on Solaris as long as QT 3.3 is installed, but I'm not sure if anyone has tried that. Note also that it would have to be a 32 bit compile, which may or may not be easy on Solaris. The current source (...) (17 years ago, 12-Mar-08, to lugnet.cad.dev)

| | | | | | (...) Hi Travis, Qt 4 provides threads. It can tell you how many ideal threads there are (presumably the number of hardware strands). Yes, the instruction set is SPARC, with 64 bit integer registers (31 of those), plus the usual 32, 64, 128 bit (...) (17 years ago, 12-Mar-08, to lugnet.cad.dev)

|
| | | | | | (...) I actually saw the "ideal num threads" call in the QT 4 documentation when I was trying to figure out how to get the number of CPUs on a Linux box. However, even though the sysconf calls are in a QT-only section of LDView's code, I can't use (...) (17 years ago, 12-Mar-08, to lugnet.cad.dev)

| | | | | (...) I recently bought an AMD Phenom Quad core running vista 64 bit. I gladly do some tests if you want. I did some thread programming myself and discovered memory/disk bandwidth is the real bottleneck with modern cpu's, just can't get enough data (...) (17 years ago, 12-Mar-08, to lugnet.cad.dev)

| | | | (...) Thank you to those of you that responded to this here or via email; I now have some good feedback, and it appears to be working correctly on quad-core machines. If anyone has access to a quad-core (or more) Linux box or Mac, I'd still like to (...) (17 years ago, 14-Mar-08, to lugnet.cad.dev)
