Hi Michel,

Thank you for the new plugin

I've just tried the new maui plugin on a PPS site which has total 6 cpu slots
and one slot is always reserved to ops & dteam sam tests:
--------------------------------------------------------
SRCFG[sam] FLAGS=SPACEFLEX
SRCFG[sam] TASKCOUNT=1 RESOURCES=PROCS:1
SRCFG[sam] PERIOD=INFINITY
SRCFG[sam] GROUPLIST=ops,opssgm,dteam,dteamsgm,dteamprd
--------------------------------------------------------

And it indeed reports correctly for non ops & dteam VOs
--------------------------------------------------------
dn: GlueCEUniqueID=ce01-pps.bgu.ac.il:2119/blah-pbs-alice,mds-vo-name=local,o=grid
GlueCEInfoLRMSVersion: 2.1.6
GlueCEInfoTotalCPUs: 5
GlueCEStateFreeCPUs: 0
GlueCEPolicyMaxCPUTime: 2880
GlueCEPolicyMaxWallClockTime: 4320
GlueCEStateStatus: Production
--------------------------------------------------------
while with lcg-info-dynamic-pbs it was
--------------------------------------------------------
dn: GlueCEUniqueID=ce01-pps.bgu.ac.il:2119/blah-pbs-alice,mds-vo-name=local,o=grid
GlueCEInfoLRMSVersion: 2.1.6
GlueCEInfoTotalCPUs: 6
GlueCEStateFreeCPUs: 1
GlueCEPolicyMaxCPUTime: 2880
GlueCEPolicyMaxWallClockTime: 4320
GlueCEStateStatus: Production
--------------------------------------------------------

BUT for ops & dteam VOs it also reports:
GlueCEInfoTotalCPUs: 5
GlueCEStateFreeCPUs: 0
while for me is seems more correct output should be:
GlueCEInfoTotalCPUs: 6
GlueCEStateFreeCPUs: 1

I've changed the reservation to
--------------------------------------
SRCFG[ops] FLAGS=SPACEFLEX
SRCFG[ops] TASKCOUNT=1 RESOURCES=PROCS:1
SRCFG[ops] PERIOD=INFINITY
SRCFG[ops] OWNER=CLASS:ops
--------------------------------------
meaning that 1 cpu slot is reserved only for ops VO queue
so for ops VO GlueCEInfoTotalCPUs=6 should be reported
BUT still the same result
-------------------------------------
dn: GlueCEUniqueID=ce01-pps.bgu.ac.il:2119/blah-pbs-ops,mds-vo-name=local,o=grid
GlueCEInfoLRMSVersion: 2.1.6
GlueCEInfoTotalCPUs: 5
GlueCEStateFreeCPUs: 0
GlueCEPolicyMaxTotalJobs: 6
GlueCEPolicyMaxRunningJobs: 2
GlueCEPolicyMaxCPUTime: 30
GlueCEPolicyMaxWallClockTime: 180
GlueCEStateStatus: Production
-------------------------------------

  Another issue is performance, see time results of 3 sample runs:
----------------
for lcg-info-dynamic-pbs

real    0m0.215s
user    0m0.070s
sys     0m0.090s

real    0m0.204s
user    0m0.090s
sys     0m0.050s

real    0m0.318s
user    0m0.090s
sys     0m0.070s
----------------
for lcg-info-dynamic-maui

real    0m1.296s
user    0m0.390s
sys     0m0.150s

real    0m1.058s
user    0m0.440s
sys     0m0.110s

real    0m1.301s
