I'm trying to do some work with java and the version keeps coming up as 1.4.2. Here is the output: java version "1.4.2" gij (GNU libgcj) version 4.1.2 20080704 (Red Hat 4.1.2-46) Is there anyway the latest version of java can be loaded up? It's my understanding that java 7 is geared to handle multicore development and I would like to look into that.
Hello IntelMTLteam / Mike,

This is the way I typically submit batch jobs:
qsub -l select=1:ncpus=40 rl-myjob
Ever since the Memorial Day weekend maintenance, jobs submitted this way have been running about 5 times slower than than they do on the login node. I traced the problem to ncpus values greater than 32. For example, on a small test that uses 64 threads and normally runs in under 30 seconds:
qsub -l select=1:ncpus=32 rl-myjob
# Finishes in about 24 seconds
qsub -l select=1:ncpus=33 rl-myjob
# Takes over 120 seconds
I can not find any information. On Friday, appeared in the console information about maintenance. When the lab will be running?
FYI, I have VNC and XMing working 100%. With the posts on the forum it's dead easy to set up. XMing is slow over long distances (I am in South Africa, even with 4mbps ADSL the latency makes X almost unbearable).
VNC is slightly faster because it only sends screen updates, and has the added advantage of persistent sessions - if the nodes aren't bounced while you are offline, your desktop will still be as you left it when you disconnected VNC. For the "purists", XMing does full XServer rendering on your remote PC, which is quite nice, but has no session persistence.
Newcomer to MTL here. My program runs fine on the Manycore Testing
Lab as long as it's singlethreaded. Whenever I enable multithreading the
performance gets worse on the same input. Starting more threads only
makes it slower.
At first I thought it was just poor design on my
part - too much contention for mutexes or something. However, now I'm
testing a program with NO synchronization between threads and
it's still happening. The performance is what one might expect from a single
MTL will be unavailable from: ~5pm PDT May 27th through 9am PDT May 31st 2011
Please plan accordingly.
Hello Team Intel Manycore Testing Lab,
Im starting a whole second thread on this topic because it is totally worth making sure the point is well understood in the Manycore Testing Lab community.
Applying for an Intel Microgrant is a very quick, very simple process. In fact, it can be as short as writing a single paragraph and submitting it. Folks, this is for money in your pocket to help you do work you are probably planning to do anyway.
