=> We are runing GM version 1.2pre16 on a SuSE 6.1 Linux distribution with
=> kernel 2.0.36 with PII processors.
=> 
=> When we test the Myrinet network with the gm_basic (or gm_allsize)
=> program we obtain good results but when it reaches 1k message size the
=> test usually fails (i.e. for gm_basic the first strcpy call fails). We
=> have also experienced the same problem for 2k message sizes. For higher
=> messages the system runs perfectly.
=> 
=> Is there any problem related to operating system virtual memory ? What
=> can be the problem? How can we fix that?

What happens when you run
host1: gm_allsize --slave --size=20
host2: gm_allsize -h host1 --size=20 -lat -b --min-len=1020 --max-len=1040

does the test complete?
