Dear colleagues,
one of our users calls within his R application an external program via
the system function very often (/home is a lustre file system):
for (i=0;i<10000;i++)
{
system("/home/user/bin/program arg0 arg1 ....");
}
The runtime for the external program is only a few seconds. With hundred
of these jobs running, the load on the meta data server goes up to 25
(2way quad core with lustre 1.8.3).
Is such a behavior known, if yes, how can I avoid it?
best regards,
Christian
